Using void smite, around 1/6 of casts release a purple nova from the target that seems to do around half the damage of the primary hit. I can’t figure out why this is happening - does anyone know where this nova comes from?
That sounds like the Fissure node which has a 0.5s cooldown.
Ah, it’s actually void rift procced from forgotten knight amulet. Void rifts haven’t appeared in the game for any skill for me the last couple of days (since I started the character), so I didn’t know what they looked like.
