I'll just link the document and explain in more detail below. (https://docs.google.com/document/d/1JpZEjYeZ81HyKReR2xTPaD4bTQlYRQFH18K0TG3YPcM/edit)
So as many people know, Cloud Brand's unleash ignores defence. What is not really known is that this only affects enemies defined in the first of the two linked lists; it will have a flat 100% success rate if the target matches any enemy in that list, and a flat 0% if it does not. This essentially makes it a dragon/reptile killer!
It turns out that Trident's ability effect does the exact same thing, but for sea creatures (defined in the second list).
Keep these things in mind when hacking the game. Or playing hacks. :P
