Defensive Support
This build would be focused on providing heals and shields, aiming to spread these amongst the team in the endgame via Community of Spirits.

Aggressive Support
This build focuses on helping allies to secure kills and make successful exchanges in lane.  Faceless Communion combined with Paralysis allows Vol'jin to follow up two Voodoo Lightning casts in quick succession to attempt to keep targets pinned and add damage, or buff an ally's movement speed via Jumping Juju once Paralysis has allowed them to gapclose.

Auto Attack Focused
This build focuses on maximising auto attack potential. Whilst the damage will not match that of other AA assassins, Vol'jin's attack speed will allow him to use abilities very quickly thanks to Darkspear Cunning, giving him flexibility.

Offensive Caster Hybrid
This build focuses on poking with empowered spell damage and basic attack DOTs through a Big Mojo/Hex of Weakness combo, weakening the target and leaving them open to being brought down by your serpent wards. A safer damage option than the AA build, and better at safe exchanges, cooldowns are focused primarily on dealing damage yourself, leaving you with less utility in teamfights.
