Abyssus for tanky character endgame

Hi. OP back after an absence, and nice to see my question started such an interesting and informative discussion. I enjoy learning more about the underlying mechanics of the game.

I have to deeply consider whether using Abyssus is a good idea or not, or maybe i will use it on the easier maps, or risk testing it out on the tougher ones, preferably right after a level-up (as i play softcore), to find out for myself.

Nothing to contribute myself here after I've tested more myself yet and gained a better understanding of the mechanics and math, but thanks to everyone who did.
