Battle Rewards

Before each wave of the invasion, you select a resource that you will be guaranteed as a battle reward if you defeat the wave. After each successful wave, you receive the reward you select, plus any prisoners you've captured during the battle. Events, upgrades, or defeating powerful heroes may provide additional rewards.

Equipment, Dark Origins, and Gold are all awarded immediately, while Abyss Materials are collected at the end of the run.

Treasure Chests
A treasure chest contains 1, 3, or 5 additional rewards. These rewards can be any normal battle reward, except the limited Abyss Materials. Additionally, treasure chests may contain combination items or legendary items.
