Armed vs Unarmed Melee combat

[The Dark]

Another idea that popped into my head because the "MMA has no mods" was bothering me:

To develop a fictional or syncretic martial art style, roll 1d10 for each of Punch, Kick, Headbutt, Grapple, Block, Escape, Diving Blow, and Throw.

DM Modifiers:
Hard Style: +1 to Punch, Kick, Block, -1 to Grapple, Escape, Throw
Soft Style: +1 to Grapple, Escape, Throw, -1 to Punch, Kick, Block

Die roll result:
0: -3 to skill
1: -2 to skill
2-3: -1 to skill
4-7: no modifier
8-9: +1 to skill
10-11: +2 to skill

I deliberately did not put +3 to skill on the chart, so that these styles won't end up with better modifiers than existing styles.
