Adjust recipe for fewell, or make materials more common
Right now fewell orbs are not worth making or buying unless you have capped Alchemy and can HQ it at a good rate, and even then it's only a slight improvement. The high cost of fewell makes most "useful" recipes not as worth it as they should be. I can understand the NPC cost being high, but fewell orbs should be easier to get than they are now. Crystals are not a good option as they're usually more expensive than the NPC cost.
I think one of two things should be done:
-Remove slime oil from the recipe, or make it more common, or replace it with something else
-Make colored rocks more common from sources other than the goldsmith guild, or lower the goldsmith guild price.
