The Oolacile Catalyst is a catalyst in Dark Souls.

In-Game Description

Sorcery catalyst of the lost land of Oolacile. Formed by enchanted whitebark branches.
Boosts sorcery adjustment, but lost land sorceries are not offensive, and attacks are not affected by intelligence.


Rare drop from Bloathead Sorcerers in the Oolacile Township and Chasm of the Abyss.


The Oolacile Catalyst is similar to the Oolacile Ivory Catalyst in that it has a flat magic adjust of 180 once the Intelligence requirement has been met. This makes it the best catalyst to use between intelligence levels 10 and 12, while tying with the Oolacile Ivory Catalyst for being the best catalyst to use between intelligence levels 12 and 28.

It has the advantage of having a lower intelligence requirement than the Oolacile Ivory Catalyst as well as being poisonous, having an auxiliary effect of 180 and a buildup of 30 per strike. Unfortunately, it is also four times heavier.

Its Poison deals 3 damage per second over a period of 3 minutes once inflicted.
