Sigil of bursting
I don’t know, and would like an answer as well. The Major Sigil is even worse because it says +5 Condition Damage +2 Vitality. I sold mine when I saw that. The Wiki at the time said Condition Duration, and so I went with that one over the Sigil of Malice because it was easier to craft. (bought the Malice) If it is 5% it is a big difference than just 5. Major Corruption gives 5 per stack up to 25 stacks or 125 at full stacks. If it does get fixed then I should probably replace the Sigil of Corruption. I suppose I could replace the Malice as well if they stack for a 10% damage increase. Condition Duration is more useful for non-damaging conditions like blind, weakness, cripple, vunerability etc. while the extra damage means you don’t have to wait as long for damaging conditions to work.
