Warrior
The warrior guild is based off of the dual strength of utter overpowering and pure thought. It is a guild based on the individual's strength, yet they stand together as a whole. The Supreme Bashar runs the guild as a general would an army. Their combined fighting force is a force to be reckoned with. The skill listing is slightly abbreviated to keep some guild secrets.

Other skills (not improvable)
Daggers
In addition to being an expert with their battle blade, warrior's can train themselves in the use of daggers.
There are 3 ways to train them:
1) throw - a quick throw at your opponent, you can do it every round.
2) stab - can't do it as often as throw, but it does more damage.
3) frenzy - unleash all your dagger skills by hitting your opponent with a myriad of daggers and normal hits.
