Challenges
The five modes on the in-game Challenge hub, with every wave, boss, rule and reward read from the game's own data and checked against the live game.
Wilderness
Fixed boss runs, four chapters, each on Normal (Ordinary) and Hard (Difficulty). Clearing a chapter for the first time pays the chapter rewards; each wave also pays a first-clear reward.
Abyssal Trial
Co-op boss fights. Four trials in order; each has a weekly first-clear reward.
Brawl
A limited-time event with its own cup count, a shared hero pool and a separate battle pass (Battle Order).
Endless
Solo wave-survival tower; rewards come from the highest wave reached, with weekly modifiers.
Duo
Two-player co-op tower. The highest wave cleared determines the reward.
