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. The sources describe her as the announcer; the added entity is the threat. 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 → stay out of the fire patches it leaves; its fire damage ignores 50% of armor (Official 0.7.0a).
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 floors on Hard Mode can suddenly gain a dangerous-tier extra entity. Which one is random from the pool above; we have no published roll table. Bring:

• General awareness from beginner guide stealth rules even when you “only” wanted floor 2 practice.
• Revive knowledge from how to revive: revives are capped at two per run, so do not spend them on Floor 2.

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.

Sources and verification

• DevForum information thread — Hard Mode Eris bullet (2026-10-09).
• Wiki Eris + Events pages — spawn list and bonus cadence (CC BY-NC-SA, paraphrased).
• Roblox badge text: There’s one More! reads “Meet Eris.” (checked 2026-11-09), which confirms she is a real in-game encounter but gives no rules.
• Illustration frames from a public gameplay video (event UI only). A frame that showed a different, common-tier entity was removed because it was wrongly captioned as Eris.
