Making auras into castable spells (TFT)

I've been trying to make custom spells using the TFT ability editor but my ideas never seem to be possible. I realize I might have to get into trigger editing for some of them, but it seems like a lot of work for what could be a relatively easy thing to create. For example, I wanted a spell that boosted the movement speed and attack rate of units significantly for short amount of time and costed mana. I tried basing this off endurance aura but I don't know how to change it to be castable instead of just an aura. I changed duration, mana cost, and other stats but it's always an aura. Is this possible?

yes, but it requires triggers.


u would make 3 different spells for each level and use triggers to give them and take them away

the problem with using auras as castables is that the spell coding for an aura is hardcoded, the game code cant be overwritten for you to do this without triggers to support what you are trying to do.
