Harp Isles creature and subspecies reference: recorded names, availability checks, and next steps for choosing an Avatar.
Harp Isles creature and subspecies reference: recorded names, availability checks, and next steps for choosing an Avatar.
Earlier launch observations recorded the names below. Current availability, unlock conditions, and stats have not been reverified. This is not a complete playable roster.
Naming correction (2026-09-16)
Two rows in earlier versions of this table were wrong. Community wiki sources list Spinus as a subspecies fork of Ecus' Laetus (written there as “Ecus' Laetus Spinus”), not as a standalone apex species — and we have found no official source that names Spinus as its own species. Separately, Ecus is not a different creature from Ecus' Laetus; “Ecus” is a shortened community spelling of the same creature. The table below reflects that reading unless the developer publishes an official roster.
| Name | Kind | Evidence status | Before choosing |
|---|---|---|---|
| Ecus' Laetus | Species | Recorded in earlier launch observations; current availability not reverified. Also written "Ecus" in community posts. | Check the live Avatar selection and any displayed unlock conditions. No current acquisition method is verified here. |
| Ecus' Laetus Spinus | Subspecies of Ecus' Laetus (community wiki) | Recorded in earlier launch observations; current availability not reverified. Earlier listed here as a standalone species. No official source names Spinus as its own species. | Check the live Avatar selection and any displayed unlock conditions. No current acquisition method is verified here. |
| Sentis' Areni | Species | Recorded in earlier launch observations; current availability not reverified. Has named variants; official event text names Sentis'Areni Fierus. | Check the live Avatar selection and any displayed unlock conditions. No current acquisition method is verified here. |
Event window closed (windows read 2026-10-04): Following the official Roblox experience build updates on 2026-09-05 15:48 UTC and 2026-09-06 05:05 UTC, the studio registered the “⭐NEW SUBSPECIES!⭐ / Sentis Attack Variant” event window, which opened on 2026-09-05 and closed on 2026-09-07. It is not running now, and no event has been registered for this universe since 2026-09-15. The Sentis subspecies joins the known creature catalog alongside baseline launch specimens (Ecus' Laetus — whose subspecies fork includes Spinus — and Sentis' Areni). Creator coverage of the September 6 build also reports console support, bug fixes, and stat changes; these are creator-reported until official patch notes appear.
Community naming (reported, not official): The Harp Isles community wiki on Fandom created a Sentis’ Areni Agrus page hours after the September 5 build (September 5, 18:08 UTC), and a creator video covering the update uses the same name — describing an attack-weighted profile (higher damage, lower health than base Sentis’ Areni). Separately, a Sentis’ Areni Arma page has existed since August 17 and describes a tanky, bleed-focused subspecies that community editors say was on the August 29 starting roster. Both community stat tables are unverified and sometimes inconsistent. The official Roblox event listing only says “Sentis Attack Variant” — confirm the exact in-game name on the Avatar selection screen before spending resources, and do not treat either community stat table as developer data. Community wiki trivia (edited September 7, 2026) additionally claims the variant released on September 5 and is purchasable in the shop for 2,000 DNA — a player-maintained price claim, not an official number, so verify the actual cost on the Avatar selection screen before spending currency. The same wiki separately documents Blorp — a small omnivore with a reported Sonic Screech stun ability — as one of the game's starting creatures; that roster claim also remains player-maintained and unverified.
Unlock & Playability Checks: Open the in-game Avatar selection screen to verify whether Sentis Attack Variant requires direct species unlocking, a mutation pathway from base Sentis Areni, or event participation. Exact base stats, sprint drain, and combat techtree prerequisites have not been published in formal developer patch notes; avoid trusting external sites promising instant unlock codes or fabricated stat tables.

Abilities on this page can also be swapped out by chip items — the chip list marks which ones replace your ability and which ones leave it alone. When a form is paid for rather than unlocked through an event, the currency behind it is on the Avatar Shards and Apex page.

Ecus, Ecus Laetus, and Spinus appear in earlier launch observations. Those records are not a current availability check or a complete roster. Confirm your available Avatars and any unlock requirements in the live game before planning around a specific creature.
The official game description identifies Techtrees as a way to improve Avatars. Check the nodes shown for your current Avatar before using the planner; a saved plan does not establish current costs, unlocks, or an optimal build.
The official description supports packing with other players, hunting, and fighting. It does not specify a required role composition or a universal best team. Agree on your group's task before choosing Avatars.
Wiki pages should point players toward the practical pages that explain what to claim, compare, build, or check next.
