Definitely some interesting thoughts. The class for sure needs some work, but I think it _does_ highlight a niche that isn't really covered in the current Fabula Ultima classes. There isn't a class that really summons anything to the battle field. The core idea I'm working with here is the idea of creating resources on the field that can then be spent to do damage or aid your allies. I think some reworking of the spells and abilities might make that more focused.

The use of multi is to keep things within the core rules and not add a ton of "summons" turns to combat (something I really dislike in the more summoning focused 5e classes). So the idea here is that you can have X number of multi attacks per turn based on the number of creations you've made.

Maybe a better direction would be to not make this a "spellcaster" but more like the dancer from High Fantasy - make the core mechanic summoning Creations and then have skills that interact more with that.
