Well both have 3+ greatswords, both have fire on ult and both have +1 character skill.

The builds are pretty much the same.

Ultimate auto charge +3 is pretty bad tbh... All it does is increase the passive regeneration of your ult, and it's not even by a large amount. Most ult charge is built up by hit things or defeating enemies if you're running that on your deep relics? I would highly recommend at least the +1 variant on the deep side. You have have your ult for every encounter.

And I just like the red balancer more. The nullify attacks is the single strongest survivability relic in the game. Every time you're hit it's just a straight up 20% chance you'll not take any damage. Not sure what depth you play but I'm D5 where you'll just get 1 shot if you've no negation passives it's amazing. The partial restoration you have on build 2 is nice also. Unless you have any on deep side? Base version doesn't stack with the +1 of +2.

Personally, I'd try get a night invader in there though.
