just a little comment

1.I wont really say much about the pros.cons.when to pick.when not to pick.and good and bad enemies.. cause i believe that there's really no hero that cannot fight another hero even if you consider them to be the hero's weakness..JUST REMEBER WHAT MOST MATTERS IS NOT THE SKILLS NOR THE HERO BUY DEFINITELY THE ITEMS!!
I'll go straight to the point..

ITEMS.
1.The only sure thing that a mortred should have is TREADS!it's self explanatory I guess.

2.Nxt is..
It provides very nice lifesteal especially for your ultimate.. but dont forget to upgrade this to in late games or if your enemies got this is the only thing you can use as for you not to feel any damage from blademail.. tip= activate this once you started hitting the enemy AND the enemy activated his/her blademail! remember this!!
You might be asking...
Why not?You got the agility,maim,ms ,atack speed, some str ,and some damage It seems perfect right? but think again but with consideration from your skills you got phantom strike with +100 attack speed for 3 attacks this explains why you dont need much agi,ms,.. you got the dagger which is spammable and has a greater slow..this explains why you dont need the maim! if your gonna say about the little damage, I'll just say Shutup!

Why not? Well the Atack speed and the chain is sure usefull but just as what i said you got phantom strike that increases your attack speed for 3 attacks.. and about the chain lighting, it's better to get some higher damage givers rather than wasting gold for this.

Why not? sure the minus armor is great!! and it gives decent damage but what if your enemy got blademail?Your already as good as suiciding. Thinking vladimirs gonna help? Well ABSOLUTELY NOT!

Skadi? Uh-umm I dont think it's rather a good idea the slow? very useless just like sny.

diffusal? well i dont like this item cause it doesnt really give that much help unless you like to be magina?

3.Gives you str, damage, and of course bash! when the bash hits the enemy will get additional 25 damage,, but that isnt really the reason why i decided to get this item, it's pretty obius you need the stun.. so that the enemy wont get far enough pretty fast and is not that costly

4. Well the anti-gang bang item this thing is sure needed for it's stats and the enemy team will have most 20% chance in success for the gangbang if not 0%..

5.Damge.. True Strike . and mini bash with additional 100 damage every minibash SAY you got any problem with this item?

6.Here i leave you with a blank space.. Thinking im stupid like spongebob? or as Patrick? why leave a space?! It's for either gem if your enemies got lothars or invi.. or aegis of immortal.. or if the gangbang really hurts and u cant escape then just make a lothars although it's counterable by gem or dust the extra ms would sure save you through hard time situations!

WAIT! you might be asking.. why you don't I see a ? Well The price is not worth-it for 6k you get 30 damage 30 agi and 30% evasion and 30% attack speed.. 1st the evasion is not stackable with the blur and it can be countered by mkb..why waste.. 30 damage instead of 30 damage why dont you just make a divine 6200 and you get 250 damage.. 30 agi and 30% attack speed, yeah this sounds good but remember you should always use your skils! cool down for phantom strike is 5 seconds with 3 attacks that has 100 additional speed! and mortred's agility gain isn't very lousy at all.. so the best thing is just add 200 gold and you get a Divine! wich is much better for the last item..

SKILL BUILD.. I'll write the order of the skills and give a reasoning at the side
1.daggerl. WHY! i'm not gonna chace enemies at level 1! well at early game it seems to be uselss but remember mortred is all weak early. fragile, weak attack.. so this pure damage can make you last hit creeps while keeping distance and it's just 25 mana quite spammable even early game..
2.phantom strike.. just in case a sure kill or low hp enemy is running..
3.blur.. You think this is useless? well it can save you from uncountable times especially when just 1 hit and your dead and then it says miss!! when your enemy just thought he/she killed you it will surely go back and will probably notice when it's too late to chase anymore..
4.dagger.. to increase the chance of last hitting
5.phantom
6.either get the ultimate or dagger.. anyways even critical wont hurt during this time
7-14. just make sure you max phantom 1st then try to make sure the dagger and blur's level are always almost the same..
15-25 max the ultimate and stats.. duh!

For a 5v5 battle
Starting gold 602..
buy.. about 3-4 sets cause your gonna get haras early game.. just get that and your off! just comeback when your hp really is just a silver or you got items stack at your base..

I will recommend that you get (the items) what I wrote earlier in order.. especially 1-3.. the 4-5 may interchange depending on you..

Game play!
once you got a lifesteal don't be afraid to just go to the neutrals and farm don't get scared to have 1-2 levels gap cause your farming..

Early game..
JUst try to last hit as much as possible using dagger.. it's just that simple

MId..-Late.. game
Well at least you got treds,lifesteal, bash/linken.. you will own the game! just make sure you dont be a stupid player and be greedy! there's no way that a greedy player is a good player.. making them go back to their base is already good enough so that you'll have time to push a little!

I'm sorry i dont got any videos nor pic from the game cause it's so bothersome to printscreen while your seriusly playing

So.. There you got it that's my guide hope you like it but if you got anycontradictions try to place reacctions and i'll try to answer your questions so pls often check my guide thankyou O=)
