Fixing skills is not my thing...
http://trac.assembla.com/FreyaWorld/changeset/111
It is custom...
but skill now has a 3 minute duration, making it dificult to re-enter pailaka for just getting the buff (exploit)
and Obliteration Storm is not counting charges, but it is usable and consumes the Critical Up buff.
If anyone has a better fix, please don't be shy
