@ Jq1790 Uh, what does SP stand for? I'm gonna assume it's speed.
And for Rasetsu Fist, just build up your physical resistance. Since it bypasses defense, that's all you really have to do. In the case of Meiling, you really should be putting money into her physical affinity anyway, sub 100 is not cool for a bulky attacker/tank.
Tenshi's HP is probably too low to handle a Rasetsu Fist. Even with a lot of physical resistance.
Also, for the fight with the Blue Oni, I would really recommend debuffing. That way Rasetsu Fist is like a paper cut.
I'm remembering the first time I fought that boss, he wasn't that hard. I just had to go Hina modo and knock off his buffs with Tenshi. Give Komachi straight physical resistance, etc.
And remember that your bonus points can be changed around. You may have to take Youmu's atk bonus points and put it in her HP just for this boss fight. (That's something I always forget)
And just to clarify, this is LoT2 right? (Barely knows anything about LoT1)
