I think Skywrath Mage is a unique hero in sense he is an early game monster, but stillcan dish out good damage during lategame. He is similar to Tinker or Tiny, which is strong early, and if get many kills, still become monster late game

[TAB]Suggested skill build
Level 1: Concussive Shot
Level 2: Arcane Bolt
Level 3: Arcane Bolt
Level 4: StatsLevel 5: Arcane Bolt
Level 6: Mystic Flare
Level 7: Arcane Bolt
Level 8-10: Stats / Ancient Seal
Level 11: Mystic Flare
Level 12-22: Depend on what you need
Level 23-25: Concussive Shots
Concussive Shot is selected at level 1 because 4s slow is very useful. And also because level 1 arcane bolt is very weak.
Then, max Arcane Bolt first. After level 3 (Level 2 arcane Bolt). Start harassing enemy with Arcane Bolt until he run out mana. You should getting sobi mask for mana regen (and its surprisingly enough).
Repeat and Rinse until you get your early Core (which is Urn, Boots, and Void Stone/another Sobi.
Gank other lane whenever you see viable (for example, 1 or 2 enemy hero is pushing far from their tower.)
Predict when Big Clash will start (usually after minute 20). You should have maxed your Ancient Seal by that time. Use Concussive right after your initiator initiate the battle. Then Use Ancient Seal to the most dangerous caster (Lion, SD, even Obsidian). Then use ulti on stunned enemy, with constanty using arcane bolt. It need quick reflex, and thats why you don;t pick him if you cannot play quickly.
