Before you go to the DLC3 new area after ending G try to farm out rare weapons/gear in the high-end stages of the Chaosdungeon. It will aid you greatly even if some stuff is % based instead of stats.
You can get the Moonlight Sword & a bunch of rare weapons from it.
Yeah, I highly recommend getting a bunch of weapons maxed out as well.
Some good weapons to max are:
Knight's sword, half damage taken + double hp buff
Bunker shield, 55% physical damage reduction
Han's machine gun, second highest spammable damage in the game, only behind the dlc 3 twin swords which take a long time to actually surpass this
Uchigatana, strong spammable aoe
Beasthunter saw, one of the strongest unavoidable attacks
Club, stun+break on hit
Greataxe, aoe fear
Anchor, +1 action buff
Andor, +1 action to start a fight
Demon catalyst/sorceror's staff if you like magic.
Gathering rings is good too, especially black rabbit rings and +3 rings, although you do get some +3 rings in dlc 3. There's also some gear that only drops in chaos dungeon, like mary's wand (unavoidable aoe dispel).
Can someone tell me how many endings there are in DLC3? or if there are multiple endings there at all and how to get them.
Just one ending but if you have
Prickett's ring in your inventory (doesn't need to be equipped) then it gets extended.
