Octimi is of a acid-like substance that can't survive on its own within two days of being sustained in sunlight, or outside period.

How does a octimi survive:

An octimi feeds off a human and or animal host. It first creates a acid like coding upon the skin or fur and burn its way into the body until it's absorbed inside. (Think of it like a sponge, when you feel it with water the droplets of water slowly aink into the holes of the sponge)

Who invented octimi:

Lol. Sorry, can't spoil that yet.

Does it multipli:

Yes, the maximum it can increase is by eight and even then it most take over the animal or human host it has.

(Lol, hope that was inetrsing and fun!)
