skill simulator give you all skills in detail with damage and all

also if you dunno when to reset ur skill, put lvl like 80 then add skill and see if some left at end

The skill simulator is incorrect on some damage/effects (with Segnale anyways). It's still good for getting a rough idea of what to get though.
