P3’s an oddity, it’s all about attack speed but most of his champs ram into artificial caps well before the max benefit of the prestige.
Because of that Taldarin and Mojo are pretty much the only ones to really take advantage of it, but body blocking is a huge concern for Taldarin.
Soo, best I could figure out is an army comp of Kaldalis and some Legionnaire mixed with Mojo and mass Scouts is probably best. Maybe with a half dozen Immortals as well.
Never gonna be as good as the other three prestige choices though…
