Mermaid gems can be weaponised!
Each colour represents an element.
I.e blue = frost
Green = venom
Red = fire.
You can destroy the gem and use its power on a weapon.
So you could use a red gem to imbue your sword with a fire burning effect.
Or frost gem in your pistol that not only damages but slows their movement speed down i.e freeze.
Whenever a weapon is charged it has so many hits until the effect wears off. Until its depleted you can enjoy a nice visual effect on your sword or weapon. of choice.
The weapon you use and which effect is up to you.
Its balanced because you need to find a gem to use and the trade of is..losing said gem as a sellable loot.
Turns it into a kind of arm-able resource like a keg but not as devastating.
Using blue gem to slow people down with your sword or venom shooting people with a sniper.
Heck, even set a ship on fire with a sniper if you use the red gem.
You have a limited amount of hits before the wffect wears off but there isnt a time limit, so you can save these hits and shots for when they matter.
For balance purposes, using fire effect on a ship will deplete quicker than using on a player but its still possible.
