For Vantage and Wrath to activate you have to have less than half HP, that's at least 20 extra damage with Vengeance, and Sorcerers can use Ruin.
This exactly. +20 Crit at half HP, with a BASE crit of 50? Combine with always going first when attacked, and a MINIMUM of +20 damage, possibly up to +42 if you decide to be a goofball and equip HP+5 and stay at 1 HP?
Say your opponent has 80 HP. Your base stats are high enough to do 30 damage. +20 suddenly takes that up to 50. That isn't a laughing matter.
If someone can get Veng/Wrath/Vantage, DO IT.
