The Thulecite Suit is an Armor that is crafted using Thulecite which is found in Ruins. It has the best durability of any armor in the game and protects from 90% of incoming damage. When worn it increases sanity at a rate equal to the Dapper Vest which makes it ideal for characters with sanity problems such as Wolfgang. Aside from crafting it the suit also has a 33% chance to be found in the Large Ornate Chest that spawns after killing the Ancient Guardian.



Using the armor to regain sanity will not decrease its durability like other clothing items, allowing infinite sanity regen as long as the wearer stays out of a combat heavy situation.
