There are five known catalysts:
- Dracon crystal
- Draconaeia oil
- Tukai stone
- Glaysker flower
- Seolarn weed
Dracon crystals are the most reactive of the five catalysts. You can make dracon powder yourself. First, follow the recipe to make draconaeia oil below. Next, dry the oil in a Wayerd pyramid to turn the oil to crystals. Once you have dracon crystals, crush them into dracon powder to be used in your potions. The ratio between oil and crystal is two to one (two parts oil dries into one part crystal). The maximum size of crystal you should make is 25 parts, any more and it won't fit into a mortar to crush.
You can make your own draconaeia oil from foraged draconaeia blossoms. Each draconaeia blossom has only one part to it, so to make draconaeia oil you need to forage a bunch of blossoms and combine them into one large piece. Then crush the combined blossom in your mortar to extract the oil. A 16 part blossom will crush into 14 parts oil. Draconaeia oil is not as reactive as dracon crystals.
Tukai is the second-most powerful catalyst. Available from Alchemy Shops or dropped in the treasure system.
Glaysker flowers can be foraged as well but are not widely spread throughout the realms.
As with healing herbs, the potency of the catalysts you can forage is related to your foraging skill. Catalysts are also improved by drying, just like the herbs. The catalyst must be crushed in a mortar before it can be mixed in a potion. The rule of thumb is dry first, crush second.
