Offlane Centaur, to be played fairly defensively at start, but as an aggressive tank/initiator when the laning phase is over.

Be sure to look out for that invis rune near your lane, is great for assisting mid kills - other than that, chill out and soak up XP whilst picking off some last hits when you're in position to.

As standard you want to be aiming for the following core items:

Tranq Boots
Blink Dagger
Hood of Defiance

From here the rest is situational
