Quas. Wex. Exort. The essence of a storm. The heart of a blizzard. The soul of a phoenix. After his people were broken and scattered to the corners of the earth, Kael was left with only the relics of his once great world. Thirsting for vengeance, he sold his own soul to Ner'Zhul, and in exchange acquired near limitless power. Taking on the mantle of the Blood Mages of old, the Invoker strode into war with nothing but the elements at his command. He can fuse the elements into deadly incantations, tearing apart the very heavens in his fury. His genius knows no bounds, and the Sentinel shall come to know the rage of the Invoker.

Let's start by looking at the Invoker's skills

Notice the weird thing about the Invoker? He has no stats at all, just skills that can be leveled up 7 times and an Ultimate that levels up 4 times. That is what is unique about him, what a normal hero would call 'spells' is in fact what the Invoker's Ultimate is for - Invoke.
Okay, to start, look at the spell description for Quas, Wex, or Exort. I'll start with Exort, what does it mean when it says 3 damage per level per instance?
It means one level of Exort deals 3 damage per level. If it's level one, that's 3 damage. The Invoker has 3 slots available for the "orbs" to go into as shown below.

Note that using hotkeys is very important to invoker. And now the effects...
-Quas (Q):0.75 Hp regeneration per second per instance
-Wex (W):2% attack speed and 1 % movement speed per level per instance
-Exort (E): +3 damage per level per instance
Here-s the mathematical formula for all you nerds out there. Exort will be used in the first example.
3 instances * 3 damage per instance * level of Exort = 9 bonus damage
So if you have all three exort reagents active at exort level 2,the bonus damage is 3*2*3 = 18 bonus damage. The same goes for Quas and Wex.
Here's a table to help you understand better.

Quas Wex Exort
Skill lvl 1 2.25 Hp 6As 3Ms +9
Skill lvl 2 4.5 Hp 12As 6Ms +18
Skill lvl 3 6.75 Hp 18As 9Ms +27
Skill lvl 4 9 Hp 24As 12Ms +36
Skill lvl 5 11.25 Hp 30As 15Ms +45
Skill lvl 6 13.5 Hp 36As 18Ms +54
Skill lvl 7 15.75 Hp 42As 21Ms +63

So at maxed level when you turn on Exort, you have +63 damage, which is quite impressive. When you turn on Quas you gain a totally imba 15.75 Hp per second! The attack and movement speed of Wex don�€™t seem that great, but combined with Boots of Speed, Boots of Travel, or even Phase Boots, you become one of the fastest heroes in the game.

I explained above that the Invoker has 3 "slots" open for his reagents, for example, if you activate Quas 3 times, it looks like this:

If you were to push the Invoke button, you will get an icon that looks like this:

So what is this? This is Cold Snap, one of the ten spells that invoke can give you.
Ok, time to get back on subject.

Pros
(+)Good Early game regen in certain situations
(+)Fast movement speed for escape/traveling
Cons
(-)Loses some farming capabilities
Spells used mainly in this build:

Skill Build (QW)
Get Invoke at level 2 and then whenever you can.
Level your reagents depending on the early situation, for example:
A harassed Invoker
1. Quas
2. Invoke
3. Wex
4. Quas
5. Quas
Etc.
If not:

Your Goals for Early Game
-Survive
-Farm
-Survive (in this order)
Laning Situations
1 Melee: This is cake for you, just peg him with your normal attack as harassment, deny and last hit like usual. Be sure to watch out for stuns/disables and you should do fine.

2 Melee: This one's a little harder, just watch out for stuns/disables and be very cautious, you can still harass with your normal attack.

1 Range: Make sure they aren't hitting you without you noticing, hit them when you have a chance but play on the cautious side.

2 Range: Call for a lane swap or tough it out. This one is a lot harder, keep your guard up and stay alert, you may need help from a teammate on this one.

1 of each: You can attack the Melee hero, just be careful for combos they may set up, again, don't get too close and you'll be just fine.
Note: An ally with a stun or disable will help you greatly in this section of the game

Advanced Early Lane techniques
Ok, so you're in the lane and you've hit level 3 and you just got your second Reagent; many options are open to you:
Option 1-Invoke Tornado (WWQ) and harass
Option 2-Invoke EMP (WWW) and harass
Option 3-Invoke Cold Snap (QQQ) and harass (not recommended)
Option 4-Invoke Ghostwalk (QQW) and escape (not recommended)
K, so for QW Invoker, these are your options.
Option 1 is decent compared to the others.
Why are the others bad?
They aren't necessarily bad but I'll show you why each one isn't suited for early game (They work better later in the game).
Cold Snap

This skill is placed on the enemy for up to 6 seconds based on Quas, which means in the early game stage, it won't hold them that long. The ministuns and increased damage may help if they have been stunned, but that's not likely the case. It's not good at all, don't even do it.

EMP

Ok, so the description says it burns up to 400 mana based on Wex, this doesn't mean it will early game, especially when Wex is level 1 or 2. It takes 2-4 seconds based on Wex, again, enemies can easily walk out of the area in 4 seconds making it not viable for harassment. Its good for keeping the enemy away from the lane for a while. Again, if used with a stun, go for it, if not, be careful when using it. It does work well if you want the enemy to back out of a lane, denying them some experience. You'd hate to waste 125 mana if you miss.

Ghostwalk

This skill costs a whopping 300 MANA, thus not making it great for anything early game except for escaping. The other problem is that this skill slows you even more than your pathetic movement speed, you'll need boots to make this work.

Now for the other option:
Tornado

Tornado does damage based on Quas and Wex, so it doesn't matter which one you level. The equation for the damage Tornado does is like this:
Damage calculation: 120 base + 21.5 per level of Quas + 21.5 per level of Wex
So, at level 3, Tornado will do 120+21.5+21.5=163 damage
The best part is that the damage will only increase as you level Quas and Wex.

When you end early game, your items should be somewhere around here:

= + +
If you are going for
Than you should have


If not, then you should be close.

Mid Game (Lvls 11-15)

Your Goals for Mid Game
-Teamfights
-Farm
-Teamfights

Teamfights
A combo you should be aware of
EMP + Tornado

Since EMP takes a while to activate, cast it and then immediately cast Tornado to keep the enemies near EMP, they take damage from Tornado and lose mana from EMP.
As the QW Invoker, your role is to support your team. When your team enters the fight, help them out with the EMP + Tornado combo, from there, attack them until one of two situations occur.

Situation 1
Enemy team is running because your team outplayed them.
Actions to be taken by you
-Cast Tornado on the fleeing enemies to trap them and then destroy them with your team
Or
-Cast Ghostwalk on yourself to slow enemies allowing your team to catch them, if needed cast Tornado from here.

Situation 2
Your team is fleeing because the enemy outplayed you�Œ.
Actions to be taken by you
-You are not as important as your team carry, sacrifice yourself to save your carry
Or
-Cast Ghostwalk to slow your enemies to let your allies escape
Or
-Cast Tornado to slow enemies (can be done from Ghostwalk preferably)

End of Mid Game
You should have:

Late Game(16-25)

Goals for Late Game

-Level Wex and Quas to power up your Tornado like usual, get one level of Exort right before you get Scepter.
-This allows you to have all of Invoker�€™s Spells at your disposal.
-Once Quas and Wex are done, continue leveling Exort.
-Using the other spells will greatly increase your role as support
-Great combos open up for you such as:
-
-This will really hurt late game with Exort leveled.
-The trick is having fast fingers and memorization.
-Invoker is most powerful at level 25

Pros
(+)Good Early game regen in certain situations
(+)Great Farming capabilities early game
Cons
(-)Loses movement and attack speed (not a lot though)

Spells used mainly in this build:

Laning Situations
1 Melee: This is cake for you, just peg him with your normal attack as harassment, deny and last hit like usual. Be sure to watch out for stuns/disables and you should do fine. Forge Spirits make your job easier in this case due to more harassment

2 Melee: This one's a little harder, just watch out for stuns/disables and be very cautious, you can still harass with your normal attack. Same as above with Forge Spirits

1 Range: Make sure they aren't hitting you without you noticing, hit them when you have a chance but play on the cautious side.

2 Range: Call for a lane swap or tough it out. This one is a lot harder, keep your guard up and stay alert, you may need help from a teammate on this one.

Note: An ally with a stun or disable will help you greatly in this section of the game

Another Note: Forge Spirits award players with quite a bit of money and exp if killed, treat them like a hero and don't just throw them out.

Advanced Early Lane techniques
Ok, so you're in the lane and you've hit level 3 and you just got Invoke; many options are open to you:
Option 1-Invoke Sun Strike (EEE) and harass
Option 2-Invoke Forge Spirits (EEQ) and harass
Option 3-Invoke Ice Wall (QQE) and harass (not recommended)
Option 4-Invoke Cold Snap (QQQ) and harass (not recommended)
K, so for QE Invoker, these are your options.
Option 1 is decent, but Option 2 has a lot more bonuses.

Why are the others bad?
They aren't necessarily bad but I'll show you each one and why (They work better later in the game).

Cold Snap

This skill is placed on the enemy for up to 6 seconds based on Quas, which means in the early game stage, it won't hold them that long. The ministuns and increased damage may help if they have been stunned, but that's not likely the case. It's not good at all, don't even do it early game. This works great late game when your spirits are attacking the enemy hero, but that's not until mid or late game.

Sun Strike

From the description, you basically get the idea, it does 75-450 damage based on Exort which is spread over all enemy units within its 200 AoE. For example: If there are 3 units that are hit by a 450 damage Sun Strike, it will do:
450/3 = 150 damage to each unit. As opposed to: 450/1 = 450 damage to one unit
It's up to you to decide if its worth it. You'd hate to waste 175 mana if it doesn't do what you want

Ice Wall

Description: Generates a wall of solid ice directly in front of Invoker for up to 12 seconds. The bitter cold emanating from it greatly slows nearby enemies based on Quas and deals up to 42 damage each second based on Exort.
Lets look at the numbers first:
Effect of Quas level:
-- slow: 20% / 30% / 40% / 50% / 60% / 70% / 80%
-- duration: 3 / 4.5 / 6 / 7.5 / 9 / 10.5 / 12
-Effect of Exort level:
-- damage per second: 6 / 12 / 18 / 24 / 30 / 36 / 42
You can tell by these stats that Ice Wall isn�€™t good early game, it should be used late game when it deals a lot of damage and slows really well
Now for the other option:

Forge Spirits

The stats of the spirits change depending on Quas and Exort, so it doesn�€™t matter which one you level. The stats for each spirit works like this:
If both Quas and Exort are level 4 or higher, 2 spirits are summoned.
-Forged Spirits have an autocast orb attack which reduces enemy's armor by 1 per hit and costs 40 mana.
-Effect of Quas level:
-- duration: 20 / 30 / 40 / 50 / 60 / 70 / 80 seconds
-- armor: 2 / 3 / 4 / 5 / 6 / 7 / 8
-- mana: 100 / 150 / 200 / 250 / 300 / 350 / 400
-Effect of Exort level:
-- damage: 29 / 38 / 47 / 56 / 65 / 74 / 83
-- attack range: 300 / 400 / 500 / 600 / 700 / 800 / 900
-- life: 300 / 400 / 500 / 600 / 700 / 800 / 900
So, this spell stacks well late game. Two spirits having 8 armor, 400 mana, 83 damage, 900 attack range, and 900 health is not something to joke around with. With the right combos, these things are dangerous, even lethal. But as far as early game works, use the spirits to harass the enemy or even kill them.

When you end early game, your items should be somewhere around here:

Teamfights
A combo you should be aware of
Ice Wall + Forge Spirits

This combo works great on single enemies as well as groups. If you can surprise them and lock them into Ice Wall, summon the Forge Spirits and kill them.
As the QE Invoker, your role is to push down towers as well as be a Semi-DPSer(this role is served much better by many other heroes).
Note: Kelen�€™s Dagger is a must for team fights to catch the enemy team off guard.
Situation 1
Enemy team is running because your team outplayed them�Š.
Actions to be taken by you
�€� Blink in front of the enemy team and slow them with Ice Wall. Proceed to destroy the enemy team.
Situation 2
Your team is fleeing because the enemy outplayed you�Œ.
Actions to be taken by you
�€� You are not as important as your team carry, sacrifice yourself to save your carry
Or
�€� Cast Ice Wall to slow your enemies
Or
�€� Blink away to save yourself (this can be done after Ice Wall)
Or

Luxury Items for QE Invoker

Desolater stacks well with the Forged Spirits armor burn, as well as adding extra damage to your attack. This is about as close to a DPSer as you�€™re gonna get. The game is usually over by the time you get this, it is a must if the game is really lasting this long.
Note: Invoker is not a DPSer, he is a pseudo DPSer, he may feel like one, but he isn�€™t, let the carry�€™s do it for you.

Bloodstone works great to keep you pumped with more health and mana.

Option 2-Invoke Chaos Meteor (EEW) and harass
Option 3-Invoke Alacrity (WEE) and harass
K, so for WE Invoker, these are your options.
All of the options are viable
Sun Strike

From the description, you basically get the idea, it does 75-450 damage based on Exort which is spread over all enemy units within its 200 AoE. For example: If there are 3 units that are hit by a 450 damage Sun Strike, it will do:
450/3 = 150 damage to each unit. As opposed to: 450/1 = 450 damage to one unit
It�€™s up to you to decide if its worth it. You�€™d hate to waste 175 mana if it doesn�€™t do what you want

Chaos Meteor

Ok, so the meteor deals up to 260 damage per sec based on Exort and up to 1550 range based on Wex. Deals minor residual damage to units that get hit.

The first think you need to know about meteor is the way it works:
1. It rolls the direction you are facing:

2. Crosses unpathable terrain
This spell takes a little practice in order to perfect. Learning how to aim the meteor is a great thing to figure out and is vital to play as Invoker.
Alacrity

This is a situational spell that can completely change the outcome in seconds. 90% attack speed and 80 damage. That�€™s no laughing matter.
Example:
You are being attacked by a tank in your lane and are passed the creep wave, you both have about equal health. Cast Alacrity on yourself, you can turn the battle completely around in seconds and perhaps even kill the enemy.
Using this spell on your team carry will seriously give you a great advantage. It gives the carry double the DPS for 9 seconds! Activate it and watch the carry pwn everyone.
Note: the carry should already be attacking when you activate it. It works great on other heroes when tackling Roshan as well.
