seems like grit doesnt work on the crawling one final boss
I have nowhere to farm now, what should I do to win? kills me instantly
How many fully upgraded weapons do you have in your arsenal & how high are your stats? Is your speed high? Can you pull off a Machine Gun move or cheese with knifes?
Do you use all your buffs? Do you switch weapons inside of combat to upkeep all their unique buff/cooldown moves? As in King Knight Sword unique buff then switch to a different weapon etc.
Using the same weapon and going unga bunga brute force is a fatal mistake in BS2.
Unless its a specific gimmick boss like Fish God with shittons of HP.
Usually you go all out inside combat with all your weapons. Or just build the insane Crit/Lifesteal katanas.
You can only really go full monkey smash if you have high enough stats.
PS: If you arent softlocked at the current location & can still go to the Chaos Dungeon. Then go farm in the CD & try to get a bunch of good rings, weapons etc.
Mabel can give you Outer Souls for a stat boost in the bossroom.
