Examples of what would happen with your summon after casting a spell.
Miasma/Bio II - Summon's next attack get's + x potency/enmity(for titan)
Bio - Summon uses x defensive ability
Miasma II - Summon uses x aoe ability
Ruin/Ruin II - Summon gains + x potency for 2 seconds, stackable up to 10 times
Shadow Flare - Shadow Flare gives summon X stat while inside of the effect of Shadow Flare.

And for the love of god, if you aren't going to give us our iconic summons, and decide to stay with these elementals, at least make them larger.
