The Pokemon Sun and Moon SOS Battle Chaining is one of the new features of the game which lets a Wild Pokemon to call an extra Pokemon to help during a battle. So, if the gamers leave the original Wild Pokemon stand and endure to defeat the Ally Pokemon, they will keep on spawning open-endedly.

According to SegmentNext, the SOS Battle Chaining is a new feature introduced in Pokemon Sun and Moon. To take the lead of this system, the gamers will have to involve a Wild Pokemon and get it to below 50% HP. With this scenario, the Wild Pokemon will be forced to call upon an Ally Pokemon to help in the battle.

Nevertheless, gamers should keep in mind that not all Pokemon have the same frequency of calling Ally Pokemon. Also, there are particular Pokemon that do not demand Ally Pokemon at all. Most often, the Wild Pokemon will call its Ally Pokemon of the similar species, but this is not a hard and fast rule.

The users could also get an item called an Adrenaline Orb from any Pokemon Centre that will increase the chances of a Wild Pokemon to call back-up. Also, it is noteworthy to mention that gamers could only use a single Adrenaline Orb in one battle.

Furthermore, iDigitalTimes noted that for Pokemon with Hidden Abilities, users will have to obtain chain to at least 30. And then they could use a Pokémon that has the Skill Swap or Entrainment attacks to perceive what capability the wild Pokémon has.

It was also noted that 30 Pokemon chain also pledges a certain number of max Individual Values (IVs). After 30, each new Pokemon is assured to obtain at least four max IVs. When it comes to Shiny Pokemon, SOS Chaining guide assures the supreme chance to bump into one of these rare Pokemon occurs after 70 Pokemon appear.

The said guide also indicated that Pokemon with the Intimidate, Unnerve or Pressure Abilities active and by instantly using super effective moves on new allies will intensify the chances of a Pokemon calling for help. Also, Pokemon has different "call" rates which will aid trainers to force a call from Pokemon that have a small call rate.

As of the moment, Absol and Weavile are the only Pokemon that is equipped with afore-mentioned aptitudes and can be knowledgeable with False Swipe. Hopefully, as the Pokemon Bank update for Pokemon Sun and Moon launches, the Pokemon with these abilities will increase.
