Invasive Monsters Combat Mechanic
Collect and Follow Clues from Invasive Monster Tracks
Unlike regular battles, players cannot deplete the health of invasive monsters. Instead, they need to collect Invasive Monster Tracks before the battle so that Rudy can provide the conditions needed in order for it to retreat.
These conditions, in some cases, will require you to switch up your roster and perform specific combat mechanics.
