Collection categories
Stackmon Types and Elemental Affinities
The seven collection types are Fire, Aether, Water, Plant, Rock, Thunder and Neutral. Elemental affinities affect battle, but a complete strength-and-weakness chart is not available yet.
Player answer
Quick answer
The seven types are Fire, Aether, Water, Plant, Rock, Thunder and Neutral. Affinities affect combat, but do not assume a familiar elemental chart until the game shows the matchup.
- Use the field guide category shown by the current build.
- Read the affinity feedback shown during battle.
- Record both sides of a matchup before treating it as a rule.
For exact details: Use live battle feedback to test strengths, weaknesses and multipliers. Treat Soot as a medal and Rift term unless the game shows it as a creature type.

How to test an elemental matchup
Before battle, note both creatures, their visible types, the move and equipment. Watch the on-screen affinity feedback, then change one variable and repeat. A single large hit may come from level, equipment or an ability rather than type.
Stackmon you can browse now
Stackpedia currently includes Flowf for Plant, Gralit for Fire, Platy for Water, Waxindle for Aether, Pomball for Rock, and Frogow, Toadox, Cahopp and Pinpaca for Neutral. Thunder has no individual profile yet.
Why Soot is listed separately
Soot appears in the story, Rift achievements and a Soot Medal. Collection achievements use Neutral as the seventh creature type, so treat Soot as a separate game concept unless the current game explicitly labels a creature that way.
Use medals as goals, not matchup rules
A Fire or Water Medal tells you there is a related progression goal; it does not reveal the Scout Leader team, route or damage multiplier. Check the battle interface for the actual affinity response.
