Thancred's Handicap Solution

[Jandor]

Garlean gunblades don't even use cereleum anyway, as they are basically just guns with a greatly elongated bayonet built into the barrel, that use gunpowder or a similar explosive to fire a solid charge or bullet out the barrel (cereleum instead is used in vehicles and machines like airships and juggernauts for fuel).

Hrothgar gunblades however use cartridges of aether to instead trigger a blast of aetheric energy along the blade and don't actually fire anything solid, hence are more like swords with an aether-powered rumble pack attached, so using cereleum in them would be a very bad idea - it would blow the gunblade to pieces if you tried to do so. Not surprisingly the hrothgar regarded Garlean gunblades as a cheap knockoff to the real thing.

I feel the Hrothgar may be more than a little biased in their assessment. The Garlean gunblade is more range focused than the Hrothgar original, but we've seen it in action enough to see it's clearly got a bit more going on than just being a gun with an elongated bayonet attached. You can't carve big magical X shaped projectiles into the air with a gun.

That said though, I also don't really a point in using ceruleum in our gunblades, we can already create all the ammo we need using either our own or a friends ability to enchant the cartridges.
