Fisch: How to Catch Photic Terrosunder and Awaken the Terrosunder

The Photic Terrosunder is a Secret, luck-favoring fish that lives in the Drylands, the region added to Fisch in Version 1.91.0. It only appears inside its own encounter, the Photic Terrosunder Hunt, and it is one of the toughest reels in the game thanks to extreme resilience and locked progress.

Quick answer: Fish inside the Photic Terrosunder Hunt in the Drylands during clear weather, in Summer, in the daytime, using Cacti Pulp bait. Reaching that encounter starts with a dust storm and the giant scorpion that awakens the Terrosunder.

Catch requirements for Photic Terrosunder

The Photic Terrosunder favors a specific set of conditions. Matching all of them raises your odds of hooking it instead of a common Drylands fish. Lock these in before you cast.

Requirement	Value
Location	Drylands
Sub-location	Photic Terrosunder Hunt
Bait	Cacti Pulp
Weather	Clear
Season	Summer
Time	Day
Rarity	Secret (Luck-favoring)

Tip: Because it is luck-favoring, higher luck stacking on top of the correct bait, weather, season, and time gives the biggest boost to your chance of a hook.

Awaken the Terrosunder with a dust storm

The encounter is tied to the giant scorpion event in the Drylands. You wake the Terrosunder by fishing behind that scorpion during a dust storm, and only one player can land the catch that triggers it.

Travel to the Drylands and wait for a dust storm to roll in. The dust storm weather only appears in the Drylands, shown by the three-wavy-line icon in the weather corner.

Once the storm is active, search the sand for the giant scorpion. Its large, sand-colored tail and body stand out against the desert.

Move behind the scorpion and cast your line into the sand right behind its tail. Reel using the standard click-and-hold minigame.

When a player lands the catch behind the scorpion, the on-screen alert reads “THE TERROSUNDER HAS AWOKEN!?!?!” and the giant red creature erupts from the sand.

Note: Only one person gets the awakening catch per scorpion. If another player pulls it first, you cannot claim that same trigger, so speed and positioning behind the scorpion matter.

Value, weight, and sizes

The Photic Terrosunder pays out 30,000 XP and sells at 0.833 C$ per kilogram, which scales into a large sum because of its massive weight. Values by weight tier are below.

Measure	Weight	Value

Average	69,000kg	57,500 C$
Base	78,000kg	65,000 C$
Maximum	163,800kg	136,500 C$

Size ratings are based on weight thresholds. A catch under 30,000kg reads as Tiny, under 59,400kg as Small, over 78,000kg as Big, and over 155,220kg as Giant.

Line up the dust storm, hook the awakening behind the scorpion, then settle in for the Photic Terrosunder Hunt with Cacti Pulp during clear Summer daytime. Once the fish is on your line, hold through the locked progress until one of those catch lines confirms the Secret is yours.
