This is so op. You can also use a grim curse instead, but it's rarer. Glyph of stone on armor compensates the low level for scroll dumping the ring (it was originally a Ring of Wealth)
I love a good broken OP combo. This one looks fun.
Armor isn't so important when you one shot all the things.
A memorable OP run I've had was with a +17 Vampiric Runic Sword with duelist the other day. Ascended with only a +2 plate.
I'd take tons of damage but it'd heal for 100-150 when using it as a weapon ability.
