It seems like one of the only builds that can do the 1000 dp/turn that you need to beat the 10th boss. If you got enough webbing you could theoretically do it with the Arakh, but I think your damage would accelerate too fast and you would end up facing the final boss without enough webbing to consistently deal 1000+ (you need 10 contiguous webs+arakh), or you would accelerate too slow and die on an earlier boss.
