However, in the Wilderness, moss giants there offer an improved drop rate of 1/60, making your key hunting significantly more efficient.
After obtaining your Mossy Key, your next destination is Bryophyta's Lair, hidden within the Varrock Sewers. Make your way to the northern section of the sewers, where moss giants typically roam. The entrance to Bryophyta's lair will be clearly visible. This is where you'll use the Mossy Key to gain access to the boss. Remember that each Mossy Key can only be used for a single attempt at Bryophyta, so it's wise to thoroughly prepare for the fight before using your key.
