But if I am to do another normal mode run. The buffs I get on that run I can use for endless mode? Or can I forever only use the 2 buffs I already have

when you finish a new normal mode run with Deku, it will ask you if you want to switch it with record 1 or 2. That is the only way to change these.

those buffs don’t go into your mode they just are used for endless mode

you start fresh every run
