Combat and raids
Chaos Dungeon
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.
Rules and numbers
- dev note Needs Slay 20 and Delve 20. Waves are generated by the server: Feeble covers waves 1-20, then each tier gets 20 waves, and corruption keeps stacking past wave 100. A wipe counts as completion.Source: raids.json (chaos, _comment)
- dev note Special drops roll once per kill, with a chance that rises with wave depth. Bands unlock at T1 wave 1, T2 21, T3 41, T4 61, T5 81 and C6 101, and the C7 band from wave 121 pays C-tier tools.Source: RaidModal.js:57-66, 2103-2110
- dev note The developer comment gives a base special rate of 0.00004762 per mob with 5 mob rolls per wave; the exact ramp is server-side.Source: Constants.js:4738-4741
- confirmed The special pool is every special-slot family at T1-T5 and C, except Extender and Reducer (slay-counter effects).Source: Constants.js:5101-5107, 5645-5670; items.json (slot special)
- confirmed The C7 band pays the C-tier tools of the 10 combat skills plus Delve; Fortify's C tool is excluded because it is a Fortress rare.Source: Constants.js:1991-2000
- confirmed Materials roll separately at 1/5 of the band's special rate: Chaos components (blade, bowstring, core) from wave 101, and the God Gem and God components from wave 121.
materialRate = bandSpecialRate / 5 (CHAOS_RAID_MATERIAL_RATE_DIV)Source: Constants.js:5109-5120 - confirmed Milestones: a Tablet for reaching wave 20/40/60/80/100/120/140, and a Glyph for reaching it within 4:00 / 8:40 / 13:20 / 18:00 / 22:40 / 27:36 / 32:48.Source: raids.json (chaos.dropTable.milestone)
- confirmed Delve XP per damage uses the band's dungeon multiplier, then 1.75 from wave 101; there is no completion XP.Source: Constants.js:881-892
- confirmed The host can auto-reset on a wave (Endless, 21, 41 ... 141) or after 1-5 party deaths (default 2, clones count); run totals carry across resets, and dead players stop earning specials.Source: RaidModal.js:15-20, 1595-1652; LoginScreen.js:289 (patch note)
- dev note Section commons roll from each cleared tier's regular dungeon table.Source: raids.json (chaos _comment)
