So your idea is literally. "Oh yeah let's break crucible by running an aoe trace (your kinetic) a debuffing trace that makes a crit spot the size of a -blam!-ing vex hydra(divinity) and an add melting trace (prometheus lense) yeah..... no. Cool concept but it just doesnt work in game. That's what most weapon concepts from fans f-up on.
Doesn’t do any damage or crit enhancement until the explosion which requires charge time. This weapon would probably be awful in PvP and is meant for mobs in pve.
