Tip overview

If Grohk uses Spirit's Domain, his lightning doesn't hit through allies, but his Shock Pulse does. He may try to stay in the front if they group to get some damage in, so use that opportunity to burst him down.

Grohk relies on totem healing to keep himself alive (most of the time). Cauterize should be first priority.

Grohk can deal massive amount of damage if he can track you properly, move randomly to set his aim off

Shock Pulse will not bounce if it hits a shield. Take advantage of this if you can as a front liner.

Shock Pulse will bounce if it hits a deployable like Ying's Illusions or Barik's Turrets. If you are playing competitive and he is picked early, avoid using these two to make Shock Pulse more difficult to use.
