Alright, so I've got something interesting; a bug that needs to be patched
IN, not out, specifically for Doubles/Triples.
Recently a new glitch was discovered on cart involving Symbiosis and Eject Button in Double/Triple Battles; if the Eject Button holder is hit by an attack that causes the item to activate while it has an ally with Symbiosis holding an item, the Pokémon switches out first, and is then given the item by its ally after it has switched out. For some reason, this causes the game to glitch, and whenever that Pokémon is switched back in, the item it was given has its effects
DOUBLED, (or in the case of Leftovers,
QUADRUPLED for some weird reason!) This glitch is shown off here:
Known effects of the glitch so far:
- Absorb Bulb activates twice (and presumably Cell Battery, Luminous Moss, and Snowball too)
- Berries that raise stats activate twice (eg. Liechi and Maranga)
- Berries that restore HP activate twice (even if the initial activation brings your HP out of the normal range for the Berry's activation)
- Black Sludge activates twice (both for Poison types and non-Poison types)
- Deep Sea Scale and Light Ball have double their effects (4x)
- Eviolite has double its effects (2.25x)
- Leftovers activates up to 4 times, as seen in the video
- Life Orb activates twice, which doubles the effect (1.69x) and doubles the recoil (10% twice)
- Rocky Helmet damages the attacker twice (R.I.P. Kanga)
- Type-boosting items (Silk Scarf and friends, plus Plates) have double the effect (1.44x)
- Weakness Policy activates twice
- Choice items and Assault Vest have double the effect (2.25x)
- Scope Lens has double the effect (+2 crit stages, or 50% crit rate on normal moves)
- Normal Gem does NOT activate twice, one of two exceptions known
- Float Stone doubles its effect (quartering weight)
- Shell Bell activates twice per attack
- Type-resist Berries double their effects (quartering damage taken)
- Leppa Berry does NOT activate twice, only other known exception
- Quick Claw does not have separate chances to activate, but shows the message twice when it does (HOW WILL THIS AFFECT THE META???)
- Starf Berry activates twice, and can roll a different stat the second time
Gimmicky and unviable as shit, but it's on cart and fun to screw around with, so it should probably be backported.
