I'm not sure if I'm entirely happy yet with the power balance of this style, but I really wanted this flavour in the game since I've always been disappointed in B/X Staff as a weapon. So here goes:
Staff Master
Type: Advanced
+2 HP, +1 Attack Bonus
- Big Stick Energy: This person has mastered the use of the staff. They ignore the Slow quality when wielding a staff. They can use the staff as a Versatile weapon, either as a double weapon (D6/D6 damage); or as a reach weapon (10ft reach, D8 damage).
Suggested learning: A local mercenary called Shad is loudly extolling the virtues of the stick. Alternatively, get their ass kicked by an old man with a stick (he will use subdual damage as he's no killer).
