The purpose of this build is to use every piece of gear that i can find that has disadvantageous procs or effects, meaning effects that reduce my own stats and effectiveness.
That said, something that needs to be understood about this build is that you cant even try to compare it to standard builds in the meta, this is first and foremost a meme style build and an exceptionally janky one at that. The aim here will never involve Crucible or SR, so clear times are irrelevant, and with that understood, Harry actually kills surprisingly fast in the theater hes designed for (MC).
Trash mobs are trash mobs, and Harry melts through the majority of them which i count as a BIG win, considering what im stuck using. Some enemy heroes do take time to kill, but most arent too much trouble which is really surprising and again a huge win for me. Ive been really impressed with the fact that ive only died once so far in Ultimate, despite activating every shrine and totem ive come across. That feels like a milestone while wearing stupid Miss Gazerman, chains of anguish, and boots of unseen swiftness.
Trust me there are tons of better gear choices i could use on this guy that could improve him, even several better choices for dodge, but then id be losing gear thats crucial to his theme (disadvantageous procs/stats).
If you happen to know any other gear that debuffs the player, or is generally terrible for the player with stat decreases, id love to hear it.
EDIT: Whoops, my bad, i never anssered the question actually. He kills by using thermite mines, coating enemies in solaels component granted skill, tossing blackwater cocktails, all of which proc devotion abilities like eldritch fire, hungering void, etc. Trash typically disintegrates and im left bouncing around between heroes, which is really fast paced and exciting. It takes decent piloting to survive. Blast shields retal damage and ring of steel add some damage. Again this is a meme of memes, so it aint like clockwork, but it IS a thrilling experience!
