>>108588209I make these sheets by making as close to a circle between canonical lore and mechanical accuracy. The system I use, Pathfinder 1e, has Werecrocodiles, and Kairyu has shown (mostly through a chibi form but still) the ability to turn into a full croc form, which is what I took as the justification for the creature type. As for the bulletproof skin, that's easily justified by the DR/10, otherwise called Damage Reduction, which for the average handgun (usually calculated at a d6 damage die) will completely negate it by reducing that damage by up to 10 points.
The rest of the build was basically built on the assumption that she does the standard crocodile maneuver of pulling someone into the water and then thrashing them about until they're dead, which this build does with frightening efficiency. So long as she's in a swampy environment, she'd be a truly fearsome foe to encounter for a low-to-mid-level party.
>>108588216I do REALLY want to do something for Henya, the problem is that outside of her canonically being, quote, "a genius", unquote, she doesn't have a whole lot going on with what she can DO. I mean I can very easily just whip up a sheet of a character with as high of an Int score as I can legally make, but like, what else? It would feel a bit empty without more to go on.
