Viego's abilities

Passive, spells and ultimate

Sovereign's Domination (P)

Enemies who fall before Viego become wraiths. By attacking a wraith, Viego temporarily seizes control of the dead enemy's body, healing for a percentage of his target's max health and gaining access to their basic abilities and items. He replaces their Ultimate with a free cast of his own.

Playing against Viego

How to counter and exploit weaknesses

1

Don't group your kills on your side: Viego can possess each body and reset his HP/spells.

2

Burst him when he exits a possession: there's a short window of vulnerability.

3

His W mist has a limited duration and he's detectable by Control Wards.

4

Focus the real Viego, not the possessed body — he'll return to his original body after possession.
