For some reason I always wanted to make a monk class for Searchers of the Unknown. At first I over-complicated the math, but after watching Kung Fu Panda 2, I had an idea.
When fighting without armour and weapons, the monk causes 1 to HD+1 damage with each hit, starting with 1d2 at first level.
Levels not reproducible with die rolls can be reproduced with the combination of two (or a simple addition of one).
Examples: HD6 = d6+1, HD14 = d12+d3
He or she starts at 2 attacks per round on first level, but otherwise advances in the described way (1 additional attack after every 4 additional HD).
The monk also reduces any damage inflicted on him or her by 1 for every odd level they possess. (-1 at level 1, -2 at level 3, etc.) This ability can be used up to as many times a round as attacks the character has (declare before damage is rolled). The DM can decide if the reduction can reach 0, or if 1 damage must always be inflicted (I suggest the former).
What do you guys think?
