I'm gathering that......
The splash damage is terrible, like I said I was peppering the entire area around the deathclaw in HIDDEN and they didn't even flinch. I think this one is going back in the cabinet at Novac......
With an Explosives skill of 50, I took Red Glare into Dead Wind cavern. It killed both Deathclaws outside the cavern, and consistently dealt enough splash damage to cripple all sorts of deathclaw legs within the cavern. However, it really wasn't effective enough for that character due to her non-explosives specialties.
I don't think there's anything wrong with the weapon...when it doesn't glitch.
