Found in Blighttown, at the scaffolding near the Valley of the Drakes. Reaching the catalyst requires crossing the trunk-like bridge guarded by Blowdart Sniper. The catalyst is found with the Crimson Set, on a corpse that is likely Yulva's.
The Tin Banishment Catalyst performs more poorly than the regular Sorcerer's Catalyst in terms of magic attack power, however, it also has a reasonably powerful spear-style physical attack - at least for the point in the game it is found - that can be used to attack enemies who get too close or finish them off without needing to cast a spell.
