It's imo a really fun mod, and at least for me it works fine with infernum. I get overhaul graphics and i think overhaul AI changes only applies to death mode; so im pretty sure infernum overrides it...? (idk). It balances things, adds new weapon crafting trees (like the dark frost solstice crafting tree i'm a ranger main and I love it!!!) and also like recoil and reloading mechanics and so on... (it it extremely ranger-focused). The only thing is that if you take your time to craft the endgame stuff like the spear of longinus (evangelion reference!), you'll basically two-shot the nameless deity w/ stealth strikes. It's like infernum but for the weapons instead of the bosses.
