“Variants for Weapons” are what I’d give the name to different weapons that are of the same type(sword & cutlass are both bladed weapons, however the cutlass has a deviation from the sword stat-wise, having 1 power, 0.9 size, 1.1 speed), these variants exist on the Bladed Weapons(sword, cutlass), Polearm Weapons(spear, trident), and Dual Bladed Weapons(dual swords, dual katanas).
Now, these are just simple concepts, they would not reflect the final stats.
Longsword - Long Bladed, 1 power, 1.1 size, 0.9 speed - Come on, this one just makes sense, when you hear “long bladed” you think longsword.
Bident - Polearm, 1.05 power, 0.925 size, 1 speed - A trident, but lighter(thus not having reduced speed), but smaller(thus having reduced size), a very simple idea.
Dual Cutlasses - Dual Bladed, 1 power, 0.9 size, 1.1 speed - just like a regular cutlass, the dual cutlasses would have similar stats, they would also mirror the dual katanas, which have 1.1 size and 0.9 speed.
These would all have old, regular, and silver(Knight’s Longsword, Knight’s Bident, Captain’s Dual Cutlasses) variants.
