power > 500, fast and risky and skill > 40 are important ones. others will lead you to dead end, differnet dialogue or not give u upper hand. memory sequnce ( when u had to choose some concepts or nothing) will give u stat buffs at the end, nothing choice will give u corrpution and skill too if u picked it 3 times. also, if power > 525, theres an interesting dead end if u want to make ascend, ressurection and eyes choice.
