- Primals work by sending out the base forme and they instantly transform on the field if they hold the Orb (similar animation to Power Construct) while in battle (they detransform if you end a trainer battle or make it come back to the ball after a Wild battle). Regarding Desolate Land:
- They have no special interaction with the Mega Gauge (doesn't consume them over time, but also don't have perma Plus moves)
- Primals work by sending out the base forme and they instantly transform on the field if they hold the Orb (similar animation to Power Construct) while in battle (they detransform if you end a trainer battle or make it come back to the ball after a Wild battle). Regarding Desolate Land:
The Primal Groudon boss battle is immune to Water, but I'm not sure about the playable one (there's no message about Desolate Land when it's out, so I assume it's not).
