Just a though how about making ss unattainable if u have certain boon. Like u
got str boon, u cannot take any str from ss, u got wis boon, u cannot get any
wis from ss. This could bring balance to the issue.
Mabbe super cha would just take out part of the ss, like u could get max
affect but could get few, but with super cha and str u could no longer get any
str from ss. And sugar on top for those low booned members of bat how about
adding spr to ss too (only for those with less then lets say 2 boons).
