I am quite happy to see Summoner Minion reforges... For AGES they were cursed with the universal and magic reforges that had nearly no effect on them: this was the reason why Ruthless was always the best reforge for a minion, because speed, crit chance (lmao) and mana cost reduction did literally nothing for those weapons. Knockback had effect, but that's too minor to be significant.
I would also like it Fabled, the reforge that seems to be the best reforge for these weapons, was obtainable on every minion. Pretty sure it'll give knockback too... In that case, we don't get to have fun with a Fabled Blade Staff.
