Random Idea #38: Gem Grenades · 5:12am Jan 25th, 2017
Possible this will eventually see use in Diary of the Dead. Crystal attached to small power source, lobbed at enemy, Golem appears, which will attack the designated target relentlessly until destroyed or its objective completed.
Hint: Steven Universe
Why? Because it amuses me.
I would claim that something similar exists in warcraft 3. Item is consumed to summon a golem to fight for you. Can't recall name atm.

Yes, but does that summom a dead-eye'd Crystal Gem to Terminator the shit out of everything around it?
