Hey there! Thanks so much for bringing this to my attention! I’m looking into Gerard's kit/damage math right now to track down what’s causing that NaN HP issue and will have a fix out as soon as I can. Really appreciate you bringing this up! <3☀️
There was a phantom calculation in Gerard's Ultimate code that was corrupting his HP stat whenever he used it...WHOOPS! But I've pushed an update, and now he should be working like a dream!
