Depth Spelunking Eris Guide — Bonus Entity Events (v0.7.0b)

Eris is not a DPS check boss like Echovore or a stare puzzle like Mannequins. She is a bonus entity event: spooky copy on your HUD, then an extra lethal guest until you ride the elevator down. This guide explains when the roll happens, what 0.7.0b changed in Hard Mode, and how to choose your response once you see her name.

What should you do when Eris triggers?

Short answer: Pause tasks, identify which dangerous entity she added, and run that entity’s counter—Eris herself will not chase you. On Hard Mode after 0.7.0b, expect her as early as floor 2, so have a generic “extra threat” plan before you are geared. If you cannot handle the spawn, skip optional loot and rush elevator power.

Read hard mode guide before stacking modifiers that also increase event rates (wiki mentions “Oh Fiddlesticks!” style modifiers—not fully verified here).

How the event plays out

1. Roll succeeds — the game picks a bonus entity event; if it is Eris, you hear/see her VO line.
2. Announcement — treat it like an air-raid siren; mark which teammate is mid-task.
3. Spawn — a danger-tier monster joins the floor’s spawn pool until departure.
4. Counter — switch to that monster’s tactics:
   • Channel-type beam steal → do not chug buffs to escape (see entities hub for that elite).
   • Apollyon → pick up consumables before he eats them (see wiki paraphrase in entities hub).
   • Jack-O-Bomber → respect fire patches with armor caps from priority/fear.
5. Extract — finish required tasks only; do not hero-clear the whole map with a doubled threat.

Wiki-listed examples of entities she can inject: Apollyon, Bullseye, Channel, The Dealer, Jack-O-Bomber, The Twins (paraphrased list, not a guaranteed roll table).

Hard Mode differences (0.7.0b)

Official changelog (Hard Mode subsection):

• Eris more common.
• Can appear starting floor 2 instead of waiting for deep floors.

That means early-level economy runs can suddenly gain a floor-30 predator. Bring:

• General awareness from beginner guide stealth rules even when you “only” wanted floor 2 practice.
• Revive knowledge from how to revive—two free meta revives still obey Recode limits.

Common mistakes

Solo vs co-op

What changed in v0.7.0b?

Only the Hard Mode frequency and minimum floor are in the published DevForum bullet list. Standard-mode floor 10+ behavior comes from wiki Events documentation, which already aligned with pre-recode design—still, always check patch notes 0.7 after Discord-only micro-patches.
