Like I said: the "armor" wouldn't be made to protect. In that case, we're not talking about the player or an NPC, but a hologram.
Slayer can throw man-shape hologram; so, what about a hologram of an "armed" gal? The hologram can be also an explosive; so, when demons are distracted by "her", BOOM, BABY! Very useful when you're in the middle of a deadly swarm.
