Sword Whip seems...

It's really cool, but I feel like the damage on it should be higher given how difficult Iga's boss fight is.

I think it's in a good spot. Its hitbox is giant and it can hit twice in one swing with good timing with a slightly slower attack speed compared to regular swords/maces, plus it counts as both pierce and slash damage for enemies that are weak to one or the other. Hell the range alone is balance enough for the lower damage, the thing's long enough to hit things from the next time zone.

It has almost no lag time when you swing it midair, not as insane as the not-Crissaegrim but still impressive. Recovery on ground is pretty harsh but the range while holding makes up for it.
So it's not the best weapon but still is very powerful.

Maybe I'll give it another look, then.

try using it while ducking. it has the usual attack delay when standing up, but it doesn't have an attack delay when ducking. you can make quick work of most bosses with the right equipment.
