Unmentioned in the patch notes, Grimoire of Sacrifice now adds a 25% DOT to Chaos Bolt. This DOT lasts 3 seconds, and refreshes back to maximum with multiple castings of Chaos Bolt. Refreshing this DOT wastes ticks and results in a DPS loss (important for Bloodlust times, for example).
Any idea if overall Chaos Bolt damage was reduced, or is this a pure buff?
