Hi! I was messing around in the generator a little, and found that mermaid runes would go beautifully with my current breeding project! I couldn't find the philter to add the trait in the diamond shop, hence this post! What would be the best way to get some mermaid philters?

There isn't a philter, as it's an LG exclusive trait.
Although there is a plan to have a trait extractor for LG traits later on.
The best way to get Mermaid Runes currently, would be to breed with a Kelp that has them.

Well that's a bit of a bummer, I like the trait but I don't want to risk messing up the project's colors! Hopefully the extraction, however it's done once it's part of the game, works better for the project!
