How to Get Gorebyss in HeartGold & SoulSilver

A trade step sits in Gorebyss's 2-stage line from Clamperl. The step cards below map each stage with catch locations and evolution methods. Clamperl shows up at solid rates, so the starting catch is the easy part.

Wild Gorebyss may be holding when caught:

Deep Sea Scale (5% chance) An item to be held by CLAMPERL. A scale that shines a faint pink, it raises the Sp. Def stat.

Catch Clamperl at any of these 1 spot to eventually evolve into Gorebyss.

2 Methods
Fastest Path

The best route is Masuda Method, about 1 in 1,639 on each try.

Step 1 · Encounter Method2 in HeartGold & SoulSilver

Masuda Method: Breed with a parent from a different-language game. Works on any breedable line.

Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.

How many you have done, or plan to do.

10%lucky few173----
25%one in four472----
50%coin flip1,136----
90%very likely3,773----
How is this calculated?

Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.

chance after N tries = 1 − (1 − p)^N,  where  p = 1 / odds per try

Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.

The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.

These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.

Where these shiny odds come from: Read our full methodology

Planning a longer hunt? Set up Gorebyss in the HeartGold & SoulSilver Shiny Odds Calculator to compare every method side by side.

Gorebyss Weakness

Gorebyss is weak to Electric and Grass. The Water typing picks up 4 resistances to work with. Gorebyss's physical bulk (base 105 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Pokemon HeartGold / Pokemon SoulSilver

Gorebyss HeartGold & SoulSilver Guide

  • Gorebyss is obtained by trade-evolving Clamperl. Catch a Clamperl first, then trade. The Deep Sea Scale must be held during the trade. Bring one over from a sibling Gen 3 game if needed.

  • Yes. Gorebyss is not available during the main story. It can only be obtained after entering the Hall of Fame. Gorebyss becomes available after the main story is complete in HeartGold & SoulSilver.

Game Availability

Since Ruby & Sapphire, Gorebyss has been in 13 games. Requiring a trade evolution to obtain means it's consistently available but requires more effort than simply catching it in the wild.
