Completely overhauls the civilized races, replacing all weapons with wrestlers, and buffing the stats of existing races.
-Increased dwarves strength.
-Made elves into monks, using Bo Staffs, and wearing robes.
-Made Humans into kung fu artists, using hands and feet.
-Made goblins into rival wrestlers.
-Replaced alot of things with a Mexican theme, so your soldiers can wear steel masks, adamantine ponchos, and of course, golden belts, and eat jalapenos.
-Doubled the thickness of humanoid skulls, so maybe fights don't instantly end with one punch.
-Kobolds now mostly scratch and bite, and also rage.

I highly recommend that you add [BABYSNATCHER] to the dwarves, so they are at war with everyone, but thats optional.
Military only defenses also recommended.
