Code:
Syntax: blitz
 
Blitzkrieg, like other skills which fighters have, can be used during
combat to increase the damage done to their enemies.  It allows those
wielding a slashing type weapon to make a single attack against everyone
in the front row of the enemy formation.  The skill can be used but once
every few rounds.
As a mentor skill (which generally means class-defining, or highly necessary) for mercenaries, blitzkrieg is 
extremely under-used.  I've never seen it used IC or OOC, not once.  This could be due to player error/ignorance (or I've just missed out on a lot, over the past year), but that seems unlikely.  I don't have a lot of experience with mercs, but I have some thoughts on the matter.
* What kind of weapons most often have slashing damage?  Swords, most obviously, but what else?  Is this part of why it's never used?
* Does it deal reasonable damage?  Does it have too much lag?
* Is it just too limited in its use (as in, versus front row only)?  Should it be expanded or adapted to increase usefulness?
