>>29867051- You can continue to bring in reinforcements even if you defeat the original pokemon you encountered at the start of battle, as reinforcements that are left alone will become the new summoner and keep the chain going;
- However, the pokemon remaining MUST be of the same family as the original. If a pokemon summons something from another species, you defeat the summoner and only that different reinforcement is left standing, the chain breaks. Evolved mons of the same family seem to be able to keep the chain going, but e.g. if a Miltank summons a Tauros and you defeat the Miltank, the Tauros won't summon anything.
- Summons provide EVs, so you use this method to just keep knocking down reinforcements and you also get a free turn for switches if you need. Also good for grinding, you could potentially chain pokemon like Chansey for Exp.
- There's a gap between reinforcements arriving so you need to be able to waste a turn with something non-damaging
- Not all reinforcements are friendly, some will actually attack the pokemon that called for help.
What we don't know:
- If there is actually a "chain", whether there actually are increasing odds for each addition - and if there's a limit to how much the probability of better stats/abilities/shiny chance.
- If there is a chain, whether it still continues with reinforcements, or simply refreshes with a reinforcement and starts a new one inside the same battle.
- If abilities such as Synchronise or Cute Charm can work on reinforcements, or if it's only for originals.
- If other, or new, out-of-battle effects can influence the reinforcement process
- It seems the Chain can be broken by other factors like paralyis, so what else can cancel reinforcements?
Basically yeah, you can get shinies and HAs any time you want in the main game, you just have to be persistent.
You get Shiny Charm if you complete Alolan Pokedex. Not sure how it works with Legendaries and Ultra Beasts in terms of being shiny locked.
