Protein

You can get protein by killing players and other things. You can get it by Robux as well.

It is used to buy ants castes, such as majors or alates.

You lose 1 protein for dying to another player

You gain 1 Protein for killing ants, ant larva, larvae bugs, and spiders

Note: Protein and food are separate resources (Protein is currency)

Some good ways to farm protein as Carpenter Alate is to go and find a crazy ant colony and raid it by your self, Yellow Crazy Ants are pretty weak and you should have no problem taking them down. Another good way is to find a abandoned colony with Ant Larvae. This works because Abandoned Colonys with ant larvae have little to no defense. Or just find a colony and kill all the larvae.

Castes you buy with protein save but paying for spider or Spiderling is a one life.
