[Pyro]

Thing is, basic attacking most of the time NEEDS those three attacks a round to remotely be worthwhile. Just by the case you've stated,you effectively screw your opponent out of 3M a turn constantly just by having an enchantment/torso slot.

Said person using the torso can also play around the aforementioned solutions rather easily -not only magic gap closers such as crescent rook are rare to not say class exclusive, that one can be played around rather easily (see, don't stand right in front of the opponent)

Low-momentum movement options like backflip, quick slide, and crane hop would easily allow you to counter it. It does nothing to ranged. Things like throwing daggers will also counter it. However, it does help against things like Cutthroat.

Momentum control is valuable but if you're reliant on getting three attacks in a round, then this is no worse than boneheart. In circumstances where it applies, it has potential to be decent. Where it doesn't, it does nothing. Most classes this affects has ways to get around it, like sidecut or magical attacks.

The most dangerous classes wearing this will be ranged users. But even then, it doesn't change much about their tactics.
