The Cave Fisher from Volo’s Guide to Monsters (pg. 130) has an action called Filament which says:
One creature grappled by the cave fisher’s adhesive filament must make a DC 13 Strength saving throw, provided that the target weighs 200 pounds or less. On a failure, the target is pulled into an unoccupied space within 5 feet of the cave fisher, and the cave fisher makes a claw attack against it as a bonus action.
Emphasis mine. I imagine its pretty uncommon for a medium sized PC’s bodyweight and carried equipment combine for a weight under 200 lbs. Does the Cave Fisher’s attack limitation include the weight of carried equipment?
