I do feel bummed when I shatter and a phantasm or two is in the mix.
To get the most out of the abilities available without feeling like I’m losing something each time I shatter, I’d personally go with 2 separate limits. Have 3 circles for clones, 3 for phantasms.
Only clones and IP count to shatter mechanics, lower the damage of clones and phantasms OR give them a time limit of existence.
Would be pretty awesome having 5-6 illusions around me during a fight >.<
