It is invincible as well, and shields are ignored. I might suggest adding in a Parallel Universe, even though you'd have to use it before you quint. It's better than using another vamp, adren, and momentum when you could just do it once, then PU and quint the second one. It'd be a bit more aether heavy though, so I'd suggest replacing 2-3 of those shields with either 2 PUs of 1 Pillar and 2 PUs, since it defeats the healing aspect of the vampires when the opponent can't damage you.
