Hi! There may be a few spells mentioned by Kingsisle themselves, but we've still never seen them in-game. Below is an example of a spell we've never seen yet.
Bounceback. It is a spell. It is first mentioned by Professor Wu in the School of Life in Ravenwood. It is written on the chalk board by the magic chalk-stick. What an interesting spell it could be! It would probably be something like this:
Title: Bounceback
School:
Pip Cost: 5
Description: (This spell could either reflect the next damage spell back to caster, or convert next incoming damage to ) Or neither lol you decide.
What do you think? Is Bounceback a life spell you want to see in the spiral? If so, what do you think it will do? If there are more spells you've heard of that are not actually real spells yet, I'd like to know!
