Limit Break Dancing (He/They)
But does a weapon have to be mechanically distinct in order to be included in the weapon list? I would argue No, it doesn't need to be.Indeed, the trident has symbolic meaning, and was included for that reason, like the sickle. But mechanically there is no way to differentiate it from a spear (which is what it was - a fishing spear).
I don't think there is anything wrong with some (or many) weapons having only cosmetic differences between them.
And by "cosmetic" I mean the shape and appearance but also the cost and weight. The weight difference between these "otherwise identical" weapons is usually only a pound or three, which is negligible even if your table is one of the rare ones that actually tracks encumbrance. Same for cost: with all of the arguments about "useless gold" in these forums, it seems most folks wouldn't notice a cost difference of 2-20gp. Tempest in a teapot.
