To be fair, this stuff works a lot better when put together, rather than viewed as a separate thing. As you yourself listed, OP, you do not really go fully into the trait line. If you did, one thing you could do is take:
Bloodthirst, Vampiric, and Vampiric Precision.
Bloodthirst will be increasing the use of every heal you get, and if you have both of the Vampiric traits listed above, that means upon a critical hit you will be self-healing twice. That on top of the previously-mentioned usefulness of a 90% health regen makes things easier. Granted, the heals are usually not HUGE, but it’s designed that way for a reason. If it were significantly larger, it would no longer be attrition so much as “I dare you to try to kill me”, if that makes sense to you.
Oh, and as it wasn’t mentioned yet on this thread I believe, Vampiric Rituals will also work when dropping non-damaging Wells including the Well of Blood. I’m sure for some that may be seen as a “Well no duh”, but if it can help further at least one person’s understanding, may as well list it.
