All Isaac Quests In Roblox Abyss

To start Isaac’s questline, you need to reach Spirit Roots and locate him at the center Safety Area. Interacting with him will trigger Quest 1 immediately.
Isaac Quest 1
For Quest 1, you need to bring specific Pacific Fanfish and Moss.
| Objective | Requirement |
|---|---|
| Pacific Fanfish | Bring 7 |
| Spirit-Mutated Pacific Fanfish | Bring 3 |
| Moss | Bring 2 |
You have to keep all required fish in your inventory. Spirit-Mutated variants appear randomly, so you will farm multiple spawns. Moss drops from treasure chests, and you need to open several treasures to collect enough.
Isaac Quest 2
To progress further, you need to complete Quest 2 after turning in the first mission.
| Objective | Requirement |
|---|---|
| Jellyfish | Bring 7 |
| Fairy-Mutated Jellyfish | Bring 3 |
| Pacific Fanfish | Bring 5 |
| Moss | Bring 4 |
Fairy-Mutated Jellyfish glow brighter than normal ones, making them easier to identify. You should double-check mutations before delivering them to Isaac.

| Objective | Requirement |
|---|---|
| Napoleon Fish | Bring 8 |
