A note on location: In the early rounds the battle location is in the preferred habitat of the better-ranked combatant in the battle, and ecology can play a huge role in what happens. Once to the Elite Trait, the battle location is randomly determined among four ecologies: Dwarf/Elfin Forest, Seagrass Meadow, Semi-Arid Desert, or Freshwater Swamp Forest for the remaining battles. The location is announced right before the battle.
