I'm on Patch 1.3.1. Logan's Catalyst is in a chest that spawns at the same spot where Logan appears after freeing him from the Archives prison. The chest only spawns after Logan goes mad and leaves that spot. I believe that happens after getting Seath's items in the Crystal Cave (which were just lying in the boss room, since I'm doing the Havel questline). I also bought all his spells before going to the Cave, so I'm not sure if that is required.

After Logan goes mad, you can find and fight him in the beginning of the Crystal Cave, just after the first butterfly. Beware of his Crystal Soul Spear, it one-shotted me the first time I've met him.
