Basic tweaks and updated description.
Additional Monk Weapons
Add Quarterstaff and Shuriken to Flurry of Blows (counts as Monk weapon) since 3.5E adds this and it makes sense and makes them more versatile
Might review "Perfect Self" which is just +1/20 DR. Having it be +3/10 or +5/10 might be more useful at that stage.
Overhaul Description
Monks are versatile warriors skilled at fighting without weapons or armor. Good-aligned monks serve as protectors of the people, while evil monks make ideal spies and assassins. Though they don't cast spells, monks channel a subtle energy, called ki. This energy allows them to perform amazing feats, such as healing themselves, catching arrows in flight, and dodging blows with lightning speed. Their mundane and ki-based abilities grow with experience, granting them more power over themselves and their environment. Monks suffer unique penalties to their abilities if they wear armor, as doing so violates their rigid oaths. - Alignment Restrictions: Any lawful. - Hit Die: d8. - Proficiencies: Proficient with monk weapons. - Skill Points (*4 at 1st level): 4 + Int Modifier. - Class Skills: Concentration, Craft Armor, Craft Trap, Craft Weapon, Discipline, Heal, Hide, Listen, Lore, Move Silently, Parry, Persuade, Tumble. - Primary saving throw(s): Fortitude, Reflex, Will. - Base attack bonus: Medium (+3/4 per level). - Special: A monk wearing armor loses their Wisdom and level based armor class bonuses, their movement speed, and their additional unarmed attacks per round.
