We know the whole crafting down fire crystals recipe and how it works, but we all seem to fall flat on the highest star level crystal, which are awfully rare.

My proposition would be to have a crafting recipe to level up your fire crystals, but also using a star equivalent orb of alchemy. Say the recipe costs 1,000 crowns, one orb of alchemy of the desired star level, and 30 fire crystals of the previous star level. This recipe would make 18 fire crystals of the star equivalent of the orb of alchemy used. (If not these values, use similar ratios of 5:3 until balanced)

These recipes would be randomly on Basil in the clockworks arcade, or reworked into mission rewards once we gain new missions. (Tier 3 boss)
