I'm sure all warriors have cringed when using berserk on the undead just as your bless wears off or similar situations and you have to sit through 7 rounds of "your attack is ineffective!". With learning the final ranks of beserk would it be possible to learn how to immediately terminate a berserk with a large stamina cost? I would hope this could be worked into the guild but if that is too good, perhaps a new cman? If it goes the cman route I would suggest even more buffs be considered to justify the points...maybe something like:

Berserk mastery
Rank 1 - berserk out of RT
Rank 2 - terminate berserk
Rank 3 - use guild skills/warcries during berserk rounds

Obviously this part could change or have pre-reqs like griffins voice or mastered guild skills but I would prefer rolling the berserk cancelling aspects into existing systems and use our limited cman points elsewhere.

Used to be you could just try to "stop berserk" (I think that was the command) and there would be a skill check to see if you do so successfully.

"After nine rounds of berserking, you can stop by typing STOP BERSERK. When you stop berserking, you receive a 20% AS penalty for 20 seconds per round you spent berserking, minimum of three minutes." -- last paragraph, http://www.krakiipedia.org/wiki/Warrior_Guild_FAQ_(saved_post)#WHAT_AFFECTS_MY_SUCCESS_WITH_THESE_SKILLS.3F

probably not but it would at least be nice to automatically cast symbol of holiness or something I mean we have some forthought while berserking since we don't kill our friends
