Stay in your wolf form as often as you can, get out your chain heal often - but do not waste your mana, get your ult on chars what are ALMOST low hp, the heal needs some time to pop and if you wait to long, your ally is most of the times already dead when your heal almost pops

The focus of this build is on your lightning shield, use it as often as you can to deal dmg and get it on chars who deal dmg with autohits first
