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 random among these four ecologies: Urban Park, Cloud Forest, Tinajas, Savanna Grassland for the remaining battles. The location is announced right before the battle.
