Wizard Spell - Summon Familiar

[Cirrial]

Can we make it so when they are killed they explode like a fireball does?

Sure I guess why not

Edit: With a bit more thought, I've decided (for my own plans to implement this) that a familiar will gain some sort of specific arcane nature (at random) that affects what familiar spells they get and what happens when they die. This arcane nature will also work as a tell for the critter, so if the wizard is running around polymorphing people the familiar can't just blend into the zoo crew. The idea is after casting a spell, during the cooldown, there'd be some sort of animation or particle effect going on around the critter until the spell cooldown finishes, whereupon they can try masquerading as an ordinary talking animal instead. what the hell did I just type

Current plans for arcane natures and spells currently undergoing some planning, but ideally the arcane natures would be something a little weirder than just your standard classical elements, as those are already well represented in the wizardly repetoire. For example, "life", "crystal", "spark", "plasma" (oh no), "vacuum/force", "machine", etc etc
