Gravecreeper

The Gravecreeper (whose name is Atlus Creeper) is a Dungeoneering boss monster that can be fought on the Occult floors of Daemonheim, requiring a Dungeoneering level of 71 to encounter and fight. It is a zombie, so it has high constitution and is weak to slash attacks. It is also weak to magic attacks, especially fire spells.

The battle
Be sure to turn auto-retaliate off when fighting with melee during this battle. This will avoid that you get killed by his special attack.

Normal attacks
It appears that the Gravecreeper's main attack is ranged, however it is only partially blocked with a protect from missiles prayer. It uses a combination of ranged and melee when a player is in melee range. This attack can drain your prayer by 1.

It sometimes shouts "Buuurrnnnn!", followed by 3x3 square puddles of purple liquid(somewhat like the portals summoned by Har'Lakk the Riftsplitter) appearing around the Gravecreeper, damaging players and disabling their prayers temporarily if they stand on them. A good way to defeat the Gravecreeper is to attack from a distance to avoid the purple liquid. If you step on the purple liquid you will lose 2 prayer points per every time you are hit.

Special attack
The Gravecreeper's main special ability is to dig himself into a plinth (shouting "Burrrrrry", "Digggggg", or "Brrainnns" just before); then, a number of the plinths in the room start to glow with a purple colour, and a few purple clouds appear. After a few seconds, all of the glowing plinths become surrounded with the purple liquid, and will remain that way for quite some time (if not cleansed).The clouds will not disappear, and act like the Corporal Beast's attack, which shoots out and splits. This can be avoided by running away from them, or teleporting out via gatestone. You can also choose to cleanse the tombs that turn purple. However this costs prayer points, but immediately brings him out from under the plinth and prevents purple plinths from turning into the puddles of purple liquid. It is best to do this, because it takes out unneeded damage to get to him while traveling on the purple liquid.

Be careful the moment after he appears again. Most of the time the room is still completely filled with purple liquid. He'll be standing in the middle of this most of the time. If he attacks you then and you are meleeing with auto retaliate on, he'll cause you to run through the purple liquid, causing massive damage (and most of the time instant death).

Trivia

 * The graves on his room, when examined, show text on "deceased" Jagex Moderators, including Mod Trick, Mod Nexus, Mod Liono, Mod Benny, Mod Hulme, Mod Reese, and Mod Chris L:
 * "Her..lies .od B.nny.."
 * "M.d Nex.s..is n. more."
 * "Rest.in p.ace, ..od Tri.k."
 * "Re.t.in peace, Mo. Ree.e."
 * "H.re..lies M.d.Hulm.."
 * "..od Li.no died h..re."

 * The music track's unlock hint originally read "This track unlocks default info", however this was patched by Jagex in a hidden update a week after its release. It now reads "This track unlocks during Dungeoneering".
 * When performing the Dungeoneering master cape emote, the player casts Fire Surge to kill a Gravecreeper in one hit.
 * After defeating a Gravecreeper in a dungeon, your Adventurer's log reads: "I killed a boss monster called: Grave Creeper in Daemonheim." However, the boss' name is spelled wrong, as "Grave Creeper" is the name for the tier 10 tree found inside Daemonheim.
