Entry & Utility Items ​

From BossRush Wiki

BossRush Ticket ​

Your gateway to every mode. Consumed on arena entry.

  • Name in the shop: Boss Rush Ticket
  • Source: Base merchant / Stock: 10
  • Required for: Standard, Infinite Hell, From Scratch, Blood Hunt, Fate Echo

Adventurer's Journal ​

In-game Wiki. Use it to browse all mod content. Supports CN/EN, updated each version.

  • Source: Base merchant / Stock: 1 / Reusable

Duck King Codex ​

A Boss collection book that keeps its own ledger. Right-click to open the codex panel and see which Bosses you've personally put down.

  • Source: base merchant, stock 1, priced at 4000
  • Use: reusable, never consumed; does not stack

The book is not what starts the ledger. The codex has been logging since the day you installed the Mod - buying late costs you nothing. The "first entry" achievement alone returns 50,000, so it pays for itself almost immediately.

See the Duck King Codex page.

Affix Forge Stone ​

The material for rolling affixes onto gear. Spent when you pick "Affix Forging" at Dingdang.

  • Source: Dingdang's shop (unlocks at affinity Lv.2, up to 5 per restock); about 8% from arena Bosses, landing wherever that Boss's normal loot lands — the loot crate in standard arena and From Scratch, the ground in Infinite Hell, the body itself in Faction War and Blood Hunt
  • Cost: 1 stone per re-roll, 2 to lock a slot (unlocking is free)
  • Stack: up to 20

See the Affix Forging page.

Relic Egg ​

An egg of one Boss bloodline. Take it to the PetNest to hatch a cub that fights alongside you.

  • Source: about 4% direct drop from arena Bosses (lands under the same rule as forge stones, so it varies by mode); or condense one at the PetNest for 240 relic souls of that bloodline
  • Use: consumed on hatching
  • Stack: does not stack - each egg carries its own bloodline, and stacking would lose that

Keep eggs in the outer layer of your bag or stash. The hatch page can now find eggs tucked inside containers too, but the outer layer is easier to count.

See the PetNest page.

Achievement Medal ​

Opens the achievement panel (or press L directly). Free from the base merchant.

  • Stock: 1 / Reusable

Bloodhunt Transponder ​

Entry key for Blood Hunt. Carried naked + ticket to trigger the mode.

  • Source: Base merchant / Stock: 5 / Quality: Epic / Consumed on entry

Fate Echo Relic ​

The dedicated key for Fate Echo. It is designed for rematches rather than a one-way entry cost.

  • Source: Base merchant / Stock: 5
  • Price: 20,000
  • Consumed: after confirming Fate Echo entry
  • Returned: after a wave-9 victory

Bring your current loadout, a Ticket, and the Relic into BossRush map selection. The Fate Contract confirmation appears after the scene loads. Canceling costs nothing; death, defeat, and an aborted run do not return the consumed Relic. See Fate Echo for full rules.

Faction Banner (7 variants) ​

Determines your faction in Faction War. Consumed on entry.

  • Random → 1 of 5 NPC factions / Scav / USEC / BEAR / Lab / Wolf Pack → corresponding faction / My Banner → Lone Wolf (hostile to all)
  • Source: Base merchant / Stock: 5 per type

See Faction War for details.
