Systems ​

A run in the arena is only the beginning. What you get afterwards, how you reshape your gear, how you raise a hatchling, how the story moves on — BossRush keeps a whole second layer of systems back at base. This page groups them by what you want to do; the full card index is at the bottom.

Where the loot comes from ​

• Loot & Rewards — Read this first: crates, cash pools and strict rewards, mode by mode
• Death Wraith — Turns one death into a rematch you have to win back
• Random Events — Supply drops, blood moons and worse: everything that can happen mid-run
• Mutator System — 28 mutators rolled at the start of a run that rewrite its rules

Reshaping your gear ​

• Reforge System — Reroll a piece's numbers at Dingdang's, lock the affixes you want with quench fluid
• Affix Forging — Reforging changes numbers; forging changes behaviour by adding affixes

Things to build and raise at base ​

• StarWish Fountain — A buildable wishing fountain for your base
• PetNest — Pick up eggs from bosses, hatch them at base, take the hatchling to war
• Arena Backyard — Farm, display trophies, pick your battle anthem; unlocked chapter by chapter through the campaign
• The Duckov Daily — One issue per in-game day, reporting on what you did yesterday
• Duck King Codex — A boss collection book that keeps its own records

Story and relationships ​

• Duck King Campaign — Six story contracts that string every existing mode together
• Affinity & Marriage — Ten affinity tiers, gifts and dates, all the way to a wedding

Tuning the mod ​

• Boss Filter — Ctrl+F10 to ban a boss or tune its weight in Infinite Hell
• Configuration — Every tunable knob and how hot-reload works
