Well, current one is totally overused, so I support a model change for the effect. T-up.

With one comes an army. A force forged from despair, built for vengeance nonetheless. Avenged thy fallen kin with one strike that comes a thousand spears. Burn thy soul with diffusion, burn thy bodies with utter radiance, split once more and land a thousand strikes. Thou shall never fear, never alone, we strike to seize thy empire!
