Drop odds

Drop odds calculator

Enter a 1-in-N rate and a number of attempts to see the chance of at least one drop, two or three, and how many hours that takes at your pace.

Every solo-combat encounter has a weighted common loot table and a list of 1-in-N rare drops. Rares roll on slay-task kills, and all combat now runs through slay tasks, so every kill rolls them. How it works: Mob drops

Collection log: mob rare drops

Every rare drop of 74 mobs in the game files.

Fortress, Chaos Dungeon and dungeon rares

Tiered collectibles rolled once per cleared Fortress wave. Higher tiers unlock deeper into the run, and each owned piece is a permanent account bonus. How it works: Fortress rares

An endless combat raid that steps through each mob tier every 20 waves, then keeps stacking corruption. Special gear, Chaos tools and weapon materials drop per kill from wave bands. How it works: Chaos Dungeon

Five-player combat raids from Feeble to Ancient: a fixed set of waves, a corrupted wave and a boss. Each completed run rolls once for that dungeon's 16 rare unlocks and pays Delve XP. How it works: Dungeons (tiered raids)

Chests, relics and pets

A completed treasure scroll becomes a chest of the same tier. Opening it pays Discover XP and several loot rolls, each of which can also hit tools, unlocks and specials; gear rolls once per chest. How it works: Treasure chests

Once-per-character relics that drop from task completions and auto-select one of a new row's 3 options by a rule (Luck, Quest, Highest Tier, Highest Quantity, Has Materials, Distance). Telescopes are passive relics from the same drop family. How it works: Task automaters and relics

Per-skill pets (normal and shiny) rolled from XP gains, plus an all-skills pet. Each is a permanent action source. How it works: Pets
