Dagannoth fledgeling

Dagannoth Fledglings are found in the room with the Fremennik Bardur inside the Waterbirth Island dungeon, near the Dagannoth Kings.

Dagannoth Fledlings are great training as they won't attack players (they're too busy with Bardur) and they have high hitpoints. Their only downsides are they are located very deep inside Waterbirth Island and they provide no Slayer experience.

Dagannoth Fledglings exist near Bardur, whom will give you cooked Sharks for players Fremennik Shields, Fremennik Swords, and Fremennik Helms.
