Domain Skills

DOMAIN SKILLS

Halibut

Six skills unlocked by Tidal Domain tier

Overview

Section titled “Overview”

Domain skills unlock as Tidal Domain tiers rise. How tiers work, and how eyes toggle, is on Abyssal Domain. More open eyes mean more skills, a wider outer ring, and stronger water-pressure damage.

Abyssal Resurrection climb speed is tied to how many eyes are open. Higher tiers shorten some cooldowns. Tier 10 unlocks extra forms.

The six skills below follow unlock order. Names match in-game localization.

01

Tidal Domain

Unlock
From tier 1
Trigger
Domain Expansion
Cooldown
~0.25s between toggles

Toggle a multi-layer tidal field. Ring count follows open eyes in the Abyssal Domain panel

Mechanics

Press the domain keybind to open or close Tidal Domain around you. Tier equals the number of open eyes in the Abyssal Domain panel, from 1 to 10. That number sets how many concentric rings exist at once.

After opening, the field expands to full radius over about 2 seconds, then stays up. The center follows you. Fish swarms and some visuals fade while you move. Press again to close. The field collapses over about 1.5 seconds. About 0.25 seconds must pass between toggles.

Weak enemies are pulled toward the center and briefly held. Foes inside take water-pressure damage every 0.5 seconds. Damage rises with tier, scales extra against bosses and high-HP targets, and applies Wet.

At tier 10 with weapon level 14, holding left click starts Aura of Overwhelming Power. Superposition Strike then uses that same endgame damage pass.

Tips: Most domain skills need Tidal Domain already open. Tier also sets outer radius, pressure damage, and how many eyes System Crashed lets you keep open for free

02

Past Self Invasion

Unlock
From tier 1
Trigger
Halibut: Past Self Invasion
Cooldown
~0.2s toggle interval

Toggle echo selves that replay your movement and shots from seconds ago

Mechanics

Toggle skill. While active, spawns as many echo selves as your current domain tier (1 to 10) and continuously records your position and shots.

Clones replay the saved path and fire when you did. Damage scales slightly with weapon level and ammo type. The nearest clone trails by about 1 second; each additional one adds about 0.5 seconds.

Turning the skill off clears clones over about 0.8 seconds. Toggle cooldown is about 0.2 seconds.

Tips: Fight normally for a few seconds, then turn it on to stack older firepower. Higher tiers cover a longer replay window

03

Fish Teleport

Unlock
While Tidal Domain is open
Trigger
Domain Teleport
Cooldown
3 seconds

Blink to your cursor inside an open Tidal Domain; out-of-range targets clamp to the outer ring

Mechanics

Only works while Tidal Domain is open; the key does nothing otherwise.

Targets your cursor in world space. If the point lies beyond the current outer ring, you land on the boundary along that direction instead.

The blink takes about 0.8 seconds: you scatter with fish, vanish, then reform at the destination. The field center follows you more slowly during the jump.

3 second cooldown, independent of domain toggles.

Tips: Use it to reposition inside an open field. Aim your landing away from enemy fire

04

Causality Reset

Unlock
From tier 5; upgrades at tier 7
Trigger
Self-Restart
Cooldown
3 minutes

Personal wrap at tier 5; tide flood and rewind from tier 7

Mechanics

Available from tier 5. Press Self-Restart. Fish wrap you for about 2 seconds, then HP refills, every buff and debuff clears, and resurrection progress hits zero. A Siren Musical Box curse lifts with it.

From tier 7 the same key is labeled wide-area restart, and the effect changes. A tide rises from the bottom of the screen and swallows a circle the size of your current Tidal Domain outer ring. Players and most enemies inside are rewound about 10 seconds. The show lasts about 5 seconds. Anyone caught in it is invulnerable for the duration.

On resolve, the caster clears every buff and debuff, refills HP and mana, and zeroes resurrection. Other players in the circle only lose debuffs; their buffs stay. They also refill and zero resurrection. Split-and-rechain worms are not rewound, including the Eater of Worlds and the Devourer of Gods from the Calamity mod.

Afterward the Abyssal Domain panel locks for a while. Higher System Crashed shortens it, about 15 to 30 seconds. On death and respawn the lock is capped at 3 seconds. 3 minute cooldown. If a wide-area restart is already running, the key does nothing.

Tips: Tier 5 is a personal panic button. Tier 7 also rewinds enemies in the tide; do not press it just after you shoved a boss into a good spot

05

Superposition Strike

Unlock
From tier 7
Trigger
Halibut: Superposition
Cooldown
~15–30s (shorter at higher domain tier)

Echo selves converge from all sides, then seven Superposition Cannons volley fish behind your aim

Mechanics

Available from tier 7. After about 1 second of gathering and 0.75 seconds of collapse, seven Superposition Cannons deploy on the side opposite your aim. Collapse locks your cursor direction.

Each Superposition Cannon charges, then fires four volleys of ten fish each. One volley deals about weapon damage × (domain tier − 6) × 2.

Base cooldown is 30 seconds at tier 7, minus 5 seconds per tier above that (about 15 seconds at tier 10).

At tier 10 with Tidal Domain open, the volley uses the same endgame damage pass as Aura of Overwhelming Power.

Tips: Best after opening Tidal Domain and holding position. Point at the target before collapse locks aim

06

Aura of Overwhelming Power

Unlock
Tier 10 · weapon level 14
Trigger
Hold LMB (tier 10 domain open)
Cooldown
None (ends on release)

Tier 10 at max weapon level. Hold left-click to keep Superposition Strike, Causality Reset, and echo selves running

Mechanics

Requires tier 10 Tidal Domain open and Halibut at weapon level 14.

Hold left mouse to sustain the effect.

Echo selves and fish continuously converge from afar.

About every 0.9 seconds Superposition Strike refreshes behind you. About every 0.6 seconds Causality Reset triggers: max HP, clear all buffs and debuffs, reset resurrection progress.

Releasing left mouse ends the effect over about 1 second. No separate cooldown; uptime depends on meeting the requirements and holding the button.

Tips: Endgame cleanup tool. Causality Reset every 0.6 seconds makes you hard to kill, but resurrection progress keeps resetting
