Obtainment
The Green Energy Crystal is found in Frigid Cavern on the left hand side of a cave near the second campsite. In it, you'll find a small fishing pond and an NPC named "???" sitting on a rock. It wears a black-ish blue hood and a black cape as it sits down next to some ice. After interacting with the NPC, the player will be given the Green Energy Crystal. The NPCs specific coordinates are (approximately): Although the Green Energy Crystal cannot be fished up, it appears in the Bestiary and can be appraised just like any other fish.
Dialogue
???: Wow, it's freezing up here! Player: You're right, I'm freezing cold!???: I can see that you're brave--climbing this mountain is not for everyone! Player: I'm fascinated by the mysteries this mountain holds.???: That's great! It's good to know that we have brave people around here. By the way, I found something interesting--I can give it to you if you'd like! Player: Of course, that would be great!???: Here it is--Make good use of it! I found it to be quite mysterious.
Notes
Despite the mysterious appearance of this NPC, they're able to talk more casually and with emotion compared to most of the Hikers on the mountain. Based on speculation, it's possible that this NPC could be a ghost or some kind of inhabitant of the mountain, which is eluded to when they say "That's great! It's good to know that we have brave people around here". This is not confirmed by the developers of Fisch. The NPC's eyes match the color of the, which could mean that they may have been exposed to or even have the power of the. Given that the most notable thing about their design is an entirely black body with glowing green eyes, it's speculated to be some kind of keeper of the. [THIS IS A BUG] It is possible to fish up the Green Energy Crystal, as from the Kraken Rod's passive "you may be able to fish up a legendary/mythical/exotic." Due to no documentation of this, we do not know the luck, or odds of this. This may be the only rod in the game to have this possibility. This also may be possible with the enchantment Wormhole, but the chances of that are significantly lower. This is considered a bug, and may be possible with the other, and.
