Moss giants are large giants, found in areas that are tied to nature. Moss giants are very commonly trained on, since their Defence level is rather low in comparison to other monsters of the same combat level, and they are vulnerable to Fire spells.

They can drop the mossy key, which is required to access the moss giant boss Bryophyta's lair for the first time, and loot her chest thereafter.

Stronger level 84 Moss Giants can be found in the Iorwerth Dungeon.

Now, for normal moss giants: If on task, including Wildy tasks, 1/75. Otherwise, if in the Wilderness, 1/100. Otherwise 1/150. ... but for the one in Prifddinas, the Slayer perk's roll (1/60) does stack with the normal roll (1/120), so you get something more like 1/40.",
