I feel the infinity buff you can choose 1 (on infi2 you can choose 2) is pretty lackluster for the cost, on damage it's pretty good, most other stats are a downgrade tho, even on lvl 700 (cap)
Stage skip also works with 800+ points invested into it, but i do not understand why there is a downgrade for such a hard to gain buff (like crit dmg is a negative dps compared to not buffing it)
- so some info can be gained, but there is also alot of bugs, so the question is always, is this intended or is this bugged
