I'm sorry, but the crystal came from SOMEWHERE.
I don't have a columi weapon, nor have I ever owned one.
You claim about research, yet I actually have the crystal, and it dropped from something outside a raid.
It was asked if anyone needed it, I said "it could be used in my legendary" and it was looted to me.
Unless of course I dreamed up the crystal, in which case maybe a GM could tell me where the hell it came from.
But it did not come from a columi weapon.
