Spirit Helpers are companion pets that provide an effect, or buff, to the player. They become more powerful along with the leveling of the player. They can be summoned by talking to NPC Summoner Shimizu. Karma is required for summoning. Spirit Helpers last 30 minutes. Multiple spirits can be bought at the same time, and can be switched be summoning without cost while the timer is still active. Similarly, logging out and logging in while within the timer will allow you to summon the spirit for the remainder of the time.
Spirit Helpers do not engage in direct combat.
