Thoughts on Thoughtless Frenzy

A few tweaks to update the barbarian

Hey crawlers,

I've updated the Barbarian! Thoughtless Frenzy has received a tweak. It can only be used once per day, it lasts five rounds, and the mind-altering effect penalty has been changed to "half your level". I feel these simple, but noticeable edits will bring the Barbarian more in line with the author's vision for ShadowDark.
