In Dark Souls, which ring increases the player's maximum equipment burden?

In Dark Souls, Havel’s Ring increases the player’s maximum equipment burden.

The ring is named after Havel the Rock, a powerful warrior associated with the Lord of Sunlight. It is found on a corpse behind a locked door in the tower beneath the Taurus Demon’s area, and the key to that door is obtained by defeating Havel the Rock.

Increasing equipment burden allows a character to carry heavier armor, weapons, and shields while preserving a desired movement speed. This makes the ring especially useful for heavily armored builds, although players must still manage their total load carefully.

Ring of Favor and Protection is a frequent wrong answer because it increases maximum health, stamina, and equipment burden together. However, it breaks permanently when removed, unlike Havel’s Ring.
