>>29801422nigger, do you even know what you are talking about?
against normal wild pokemon, there is a random chance at the end of each turn that they will summon an ally
the consumable guarantees summons at the end of each turn
each summoned ally has a slightly higher chance of improved stats and shininess, likely the same scaling as the old pokeradar
if you are shiny chaining, this is literally what you want, as you won't even have to exit battles, you can simply stay in the same one until it summons a shiny ally.
