A few thoughts and ideas about Warrior Monks in combat.
Unarmed Monks obviously use their bodies as weapons. Standard unarmed combat damage is 1D6 +Personal Adds. Warriors get to add their level to their HPT. Monks use 1D6 per level + Adds + level to determine HPT in combat.
Monks using weapons get the Warriors benefit of adding their level to their HPT.
Monks wearing no armour can deflect 1D6 points of damage per level, this includes damage from magical attacks which would otherwise bypass armour and shields, but does not apply to Spite Damage. Monks take spite damage normally. Monks wearing light armour do not get the Warrior's doubling benefit, but may add their level to the Hits absorbed by the armour.
