Affinities

Arena battles turn on affinity. Each of the 8 affinities hits one affinity hard and one weakly, and takes extra damage from one and less from another, so pick a companion that counters your opponent.

Matchup chart

Toxic	Tropical	Frost	Radioactive	Desert	7 Toxic species
Mechanical	Desert	Anomalous	Tropical	Frost	9 Mechanical species
Anomalous	Radioactive	Fire	Mechanical	Tropical	8 Anomalous species
Desert	Toxic	Tropical	Fire	Mechanical	4 Desert species
Tropical	Anomalous	Mechanical	Desert	Toxic	10 Tropical species

Attack is the damage a creature deals: extra against its strong affinity, reduced against its weak one. Defense is the damage it takes: reduced from its strong affinity, extra from its weak one. The game shows both on each creature's Attack Profile and Defenses panels. Strong attacks run in one loop: Mechanical, Desert, Toxic, Tropical, Anomalous, Radioactive, Fire, Frost, then back to Mechanical.

Each affinity links to the species table, filtered to creatures with that affinity.
