I just started UHVM on Maya at 52. Got my Axton to pass me a 50 slag rubi, but any rubi will do with ruin.
If your getting low on health, equip her and hit the enemy with ruin and Bing your back on full health. I cannot recommend it enough for UHVM.
I have ruin, nothing in harmony tree and 3 points into sub-sequence. Once i have SS 5/5 i will start on sweet release , as I reckon in UHVM i will be about 58 and will need healing a bit more by then
