Dagannoth guardian

Dagannoth guardians are level 148 Dagannoth that lurk in the southern caverns of Waterbirth Island leading to the Dagannoth Mother (Blood Runs Deep). Compared to other Dagannoth inhabiting Waterbirth Island, they are relatively inaccurate. Like all Dagannoth, they are weak against Balmung making them good for slayer tasks and even training because of the high life points and high slayer xp.

They seem to be aggressive to all players and do not become tolerant after a certain amount of time. Like Goraks, they will always attempt to attack whether or not the player is already under attack, even though the area is not multi-combat.

Dagannoth guardians do not drop charms.

If you use your Protect from Melee prayer/Deflect Melee curse, the Dagannoth guardian will use its ranged attack until it dies or until you put a Missile prayer on, at that point, it will go back to its melee attack.

You should also note, that you cannot use a dwarven multicannon in the dungeon. You'll get a warning that it's too dark to work properly.
