When used from the Bag during battle, makes wild Pokémon more likely to call allies for help in an SOS Battle. In Pokémon Ultra Sun and Ultra Moon, wild Pokémon will only call an ally once per battle unless the player uses an Adrenaline Orb. It is consumed after use, and can only be used once per battle. If used repeatedly, Adrenaline Orb will fail and will not be consumed.
If the holder is affected by Intimidate, it consumes the Adrenaline Orb and its Speed is increased by one stage. It is not consumed if the holder already has +6 Speed stat stages (unless its Ability is Contrary, in which case it won't activate if the holder has -6 Speed stat stages). It is consumed even if the holder is not affected by Intimidate due to its Ability (e.g. Hyper Cutter) or Mist, but will not activate if the holder is not affected because it already has -6 Attack stat stages (or +6 in the case of Contrary).
If multiple Pokémon each holding an Adrenaline Orb are affected by Intimidate, each Pokémon will be affected by Intimidate and consume their Adrenaline Orb before Symbiosis transfers any item (including Adrenaline Orbs).
