The ring of the master cat is an artifact ring. It is the reward for the frustrating task of pleasing the cat lord — by killing no cats at all until you reach him. Whilst worn the ring increases PV by 5, Dexterity and speed by 16 each, and grants the Fate Smiles intrinsic. As of ADOM v. 1.2.0 it also grants an increased chance to land critical hits in melee when worn; this only occurs in earlier versions if the ring is actually wielded as a weapon, due to a bug[1].
