There's something seriously wrong...

[Fermouth]

Both of my characters are able to crit for over 400 damage in one hit naked.
Their max normal hits are over 90.

And this is without any gear or spells.

Now during normal combat I use several spells.
My mystic uses way of the tiger and way of the monk.
My priest casts profane link, hellfire shield, and unholy fanaticism.

That's it.  So yeah.  Might want to look into this.

This has been fixed.  It was caused by stacking of abils which could be accomplished in parties.
