==Effect==
===In battle===
If a Pokémon with Symbiosis has a held item, immediately after an ally's item is consumed, the Pokémon with Symbiosis will pass its item to that ally. Symbiosis may pass an item to a non-adjacent ally in a Triple Battle. 
Symbiosis triggers any time an ally Pokémon consumes its item, whether directly or through the use of or . If a Pokémon eats another Pokémon's Berry with or and is not holding an item, its ally's Symbiosis will be triggered and give an item to the Pokémon that used that move. An Air Balloon popping will trigger Symbiosis. If multiple Pokémon on the same side of a Triple Battle or Horde Encounter have Symbiosis, then Symbiosis will trigger on the faster Pokémon (even while is in effect).
Symbiosis will not trigger if an ally's item is moved to a different Pokémon (such as due to or Symbiosis itself), destroyed by , or knocked off by .
If a is consumed in response to an attack, Symbiosis will not activate until after the damage is received. If an item is consumed using Fling or Natural Gift, Symbiosis will not activate until after the move deals damage.
Symbiosis cannot transfer a Z-Crystal. It cannot transfer a Griseous Orb if either Pokémon is , a Plate if either Pokémon is , a memory if either Pokémon is , a Drive if either Pokémon is , a Mega Stone if either Pokémon can Mega Evolve using it, a Blue Orb if either Pokémon is , a Red Orb if either Pokémon is , a Booster Energy if either Pokémon is a Paradox Pokémon (except , , , , and ), or a Mask (Cornerstone Mask, Hearthflame Mask or Wellspring Mask) if either Pokémon is .
====Generation VI====
If the ally of a Pokémon with Symbiosis consumes a Gem by using a move, Symbiosis activates immediately. If the item would normally affect the power of the triggering move, then the new item's effect will be applied immediately; if a consumable item (except another Gem) is received that can currently be activated, it will immediately do so. However, if a Plate or Drive is given to a Pokémon using or after it has consumed a Gem, the move's type will not change; likewise, if the Pokémon receives another Gem via Symbiosis due to consuming a Gem, it will not also consume the new Gem.
In Generation VI, if an ally's Eject Button is consumed, Symbiosis will activate and transfer an item to that ally after it switches out but before its replacement is sent out. When this Pokémon has switched in again, the Pokémon's item will be affected by the Symbiosis Eject Button glitch, which causes certain items to apply their effect twice.
====Generation VII====
If the ally of a Pokémon with Symbiosis consumes a Gem by using a move, Symbiosis does not activate until after the move is executed.
The Eject Button activating does not trigger Symbiosis.
===Outside of battle===
Symbiosis has no effect outside of battle.
