Catalysts are used in the creating of Celestine Ward Armor.
A catalyst is used together with the same tiers of Ancient Tattered Light Armor, Ancient Ragged Medium Armor, Ancient Rusted Heavy Armor, an Ancient Ritual Candle, an Ancient Ritual Rune and an Ancient Ritual Tome
Depending on the requirements of the armor piece you want to create, different candles, runes and tomes are combined together at the Ancient Ritual Stone.
They can be obtained from Thorian Glowban for free, provided you have the right amount of faction (see the specific catalyst for faction requirements.)
Opposed to Ancient Ritual Candle, Ancient Ritual Rune and Ancient Ritual Tome they come in four tiers. However, the last tier is only gained once the quest, Ancient Weapons of Leth Verael, has been completed.
Tier 1 Catalyst is:
- Bubbling Catalyst which is a vial with a red substance.
Tier 2 Catalyst is:
- Coagulated Catalyst which is a vial with a blue substance.
Tier 3 Catalyst is:
- Foaming Catalyst which is a vial with a green substance.
Tier 4 Catalyst is:
- Purified Catalyst missing info.
