I'm trying to catch a Castform. My understanding is it only arrives as an SOS Pokémon when weather is active. So I've got a Smeargle built for chaining and I'm fighting on Route 17. I've been through about a dozen Fearow, and they've called in a couple of Goomy, which I killed immediately to keep the Fearow around. I'm trying to make sure I'm doing everything right. I can't find anywhere that seems to explain SOS clearly, so I'm trying to figure out which of 3 cases is true:
- I see chains are "broken" if a Pokémon not in the same family is summoned. Does that mean when Goomy was summoned, the chance of a Castform being summoned later vanished? (More Fearow have been summoned since then.)
- Whether Goomy or Castform appears is related to which Pokémon I'm fighting, and Fearow will not summon Castform.
- I'm waiting for a particular dice roll, and it hasn't favored me yet.
I'm assuming (3), but need to know if (1) or (2) is true so I'm not wasting my time.
I found a friend who was willing to trade for a Castform and moved on. When I was trying to catch a Vanillish, the first hail SOS was a Castform. Go figure. I think this does confirm there's nothing wrong with this process, but that Castform's a pain in the butt.
