Stormvermin have two running attacks. One is a running swipe, the other is a running stab. Both attacks have the same hitbox.
Comparison of hitboxes recording:
The red boxes represent the hitboxes.
Image of the running stab hitbox (at 0:03 in the recording):
Image of the running swipe hitbox (at 0:10 in the recording):
This hitbox is appropriate for the running swipe, but not the running stab.
For reference, here’s the overhead hitbox (at 0:20 in the recording):
Note how the overhead’s hitbox is narrow, which is appropriate for the type of attack it is visually.
Attempting to dodge it, slightly too early timing with the Rapier + Charmed Life (1.45 dodge range) recording:
The attack is difficult to dodge even with a massive dodge range. I imagine it’s very annoying as a client.
The hitboxes were displayed with the melee weapon arcs mod.
