I think it 100% makes sense for claw rune words in
- Crescent Moon
- Lawbringer
- Plague
I have been campaigning pretty hard for Plague to be shield, claw, and dagger.
I would be interesting to see what it would be like to include the most 2 and 3 rune weapons. Probably broken but here are some thoughts.
- Leaf - Simple to make, the sorc bonus is lost on the sin, but good uses for Fists of Fire and Dragon Tail. Probably broken for fire traps though.
- Black - Would for sure assassinate bosses.
- Edge - Would assassinate undead/demons
- Steel - I mean who cares either way on this one but still think claws would be fine.
- Zephyr - Would be fun early on
- Kings Grace
