Summoning Orb (Invading)

Name: Summoning Orb (Invading)
Appearance:

The Orb:

Backstory: This item fell when you won a fight against a strange opponent.

Ryo Value: -

Health: -
Trait: This orb's ability is activated by you crushing it and sacrificing 25 HP to summon an Invading S-Rank NPC that you won against. The NPC lasts for only the thread in which it is summoned, cannot teach any of its jutsu/skills/abilities to the user nor give any items in their inventory (including organs).

Unlike Stationary NPCs, Invading NPCs are feral and will not heed orders from the user or anyone else: They will attack every other player or creature in the thread besides their summoner autonomously.

These Invading NPCs can stay in a thread for up to 6 posts before they vanish entirely, and all jutsu they cast- if not dismissed already- last 1 post after the NPC's exit.
