Wisp

Appearing

After it is unlocked in the story, a Wisp can appear during a battle (not in online battles). Pinning it gives one bonus for that battle.

Chance

Chance at each check = level part + turn part.

Bonus

  • The game checks every sixth turn while no Wisp has appeared yet. Summon: “Will make Wisps appear more often.” multiplies the chance by 1.5.
  • Bonus: one of five with equal odds (only the first four if no enemy can be befriended; only the first three in some special battles). 10% of Wisps give the stronger version.

Befriending Wisp

  • Normal: +10% befriend chance for every enemy.
  • Strong: +100%, so every enemy that can be befriended wants to join. Only one Yo-kai joins per battle: the rarest one.

Befriending Wisp

The bonus depends on the enemy’s befriend class, so even the strong Wisp is not a sure befriend.
