I got this idea from when me and my friend casted storm sharks and i fizzled but his hit but was reduced by a shield.
This idea is that when 2 people cast the same spell they can combine the spells to make a new type of attack. like for example storm sharks. 2 people cast the same one and the same enemy and combines them to make a shark frenzy that does like 375-435 + 375-435 damage (or whatever storm shark does).
Plz tell me your idea of this even if you dont really understand what this is saying reply on what you do understand :D
