The stuff I have are Eto, Noro, and tatara, which should I replace? im using tatara to fight, eto to maybe grind or just chill, and noro is just bosses, Im seeing if Kosshi is good for fighting or Grinding, I need levels and people are targetting me, what should I do?

Tbh you should stay with Noro due to it's health insane regen and it's life steal it makes a great way to farm bosses in just one single run (Pro tip get sacrifice for your special when using Noro. When you attack the object you made you can heal attack it. It's a really great way to heal quickly..)
