Three words.Sage Soul Degeneration.
Sage summer sprint is really useful tbh, like the times you get blood vow/amp/hf (any annoying debuff really). Also, when a sin freezes you so you can't run, I've died a few times as Demon because stuck like that with nothing left. Sage soul degeneration then amp is idol. I've switched between sage and demon wf atleast 7 times because both versions are so fun.
