Los Karatecas

My latest DCC campaign is influenced by the Santo film, La Furia de los Karatecas. I wanted to include some type of monk (which DCC does not have), so I turned to the OSR Monk class from Venger Satanis' The Islands of Purple-Haunted Putrescence. There is a fairly basic monk there that would work for my purposes, but I also do not want two things to happen:

1. los karatecas should not be significantly cooler than characters
2. los karatecas are henchmen of the real bad guys, and should not outshine them

So, I am making them scalable.

• AC is 11 + 1/2 hit dice (level), rounded down
• Hit Dice: 1d6 per "level"
• No armor
• Simple weapons
• Los karatecas get a deed die, as a warrior of the same "level", which can be used as follows:
• Every round el karateca gets to concentrate on an opponent they roll a deed die; on four successes (3 or better) they have found a weakness they can exploit for
• double damage on next damage roll
• knock opponent prone
• reduce a physical ability by 1
• Alternately, they may (on a successful deed) distract opponents, allowing an ally advantage on their next attack, or an ally may flee combat freely
• Karatecas may "dual wield" as normal, but do not gain the below benefits.

Los Karatecas get the following per "level" with open hand attacks

1. d20 action die, 1d4 damage
2. d20 action die, 1d6 damage
3. d20 action die, 1d8, d14 action die, 1d4 damage
4. d20 action die, 1d10 damage, d14 action die, 1d6 damage
5. d20 action die, 1d12 damage, d16 action die, 1d6 damage
6. d20 action die, 2d6+1 damage, d16 action die, 1d8 damage
7. d20 action die, 2d4 damage, two attacks per round from here on
8. d20 action die, 2d6 damage, attacks count as magical
9. d20 action die, 2d8 damage, 1 in 6 chance of stunning for 1d4 rounds
10. d20 action die, 2d10 damage, 1 in 3 chance of stunning for 1d4 rounds
