Eh, the artifacts are bad in execution because they're still a sizeable power increase, but there was nothing wrong with him getting them in concept.
I have a serious hatred for Luni so I won't even try to object to that part.
As for Val being unstoppable, as long as I didn't fail my init roll that I have a big lead on compared to Kanz (assuming I'm not providing him with my bonus in a combat situation, I have +8 on him), beating him in combat would be simple. Fly into range, IP, Hellfire Grasp, AP, Shock Spiral. I calculate a total average damage of 173 lightning and 10 fire/necrotic, easily enough to knock him to 0. Add in a Weapon of Speed Elemental Bolt and we're in probable-instant-kill territory (ie below negative bloodied).
