Ostilli Host
A symbiotic organism fuses to the body over weeks, channeling magical feats through a bond that leaves its host weakened if torn away.
Uncommon
Ostillis are amorphous organisms that combine characteristics of both plants and animals. Typically found in subterranean environments, they can share a symbiotic arrangement with surkis. When a magic-gathering node on a surki’s body is damaged or absent, an ostilli is placed on it like a bandage, and after several weeks, the creature fully fuses with its host and becomes a makeshift node, accumulating the magical nourishment that the surki needs to survive. With training, surkis—and increasingly, members of other species—can direct these tiny symbiotes to a variety of magical feats.
If your ostilli is ever removed forcibly from your body (which requires a successful Medicine check against a hard DC of your level and 30 minutes of delicate surgery), you are fatigued and can’t use any of your ostilli’s actions until your ostilli is reattached. This requires you to hold your ostilli to the place from which it was detached for an uninterrupted hour. If the ostilli isn’t reattached within 24 hours, it dies.
