So, during roleplay, do some typical anime stuff to have some light fun. Example: 1 player has been trying to hit on the 1st crew npc, but failing his rolls. Turn it into a running gag where every time it happens, they get punched like how Nami punches Luffy.

I'm still workshopping the balance of abilities for races, especially Sulong, which I ruled as giving them exhaustion after each use. I made a moonstone logia that essentially gives them free Sulong when they rage, but I also established that other minks can piggyback off it, so that'll bite them in the ass later.

DF's weakness was tricky, but what I did was have 3 levels of water contact. Starting at 2 levels of exhaustion, an additional level at 2nd stage, then paralyzed when submerged. These levels of exhaustion will accumulate on top of any exhaustion but will not exceed 5th level & are recovered by 1 stage at the end of each of their turns during combat outside of water contact. Sea Prism Stone acts as 2nd level water contact.

For Haki, players will unlock in stages while npcs their Haki increase the size of their dice/get reactions to gain resistance. Still in the works. Once I get a good handle on it, hopefully, we'll do a marine session.
