Moss Giants are large, humanoid creatures found in the Iorwerth Dungeon.

These variants of Moss giants are not very commonly trained on, since their Defence level is higher than other varieties, and they also use a magic attack. They are just as vulnerable to Fire spells as other moss giants, and safespotting is recommended as they only use their magic attack within melee range.

They can drop the mossy key, which is required to loot the chest defended by the moss giant boss Bryophyta, and do so at a higher rate than normal moss giants outside of the Wilderness.
