Monster Manual III
Six squat, powerful legs support this stone automaton's thick, insectoid body, which is wider and lower to the ground than a horse's. The creature's stable bulk supports four serrated blade-arms that whirl around with vicious speed.
Slaughterstone eviscerators were originally built by dwarves to defend their strongholds; now, other underground races have started to build their own versions of this deadly construct. Made for war, a slaughterstone eviscerator has powerful blade-arms capable of tearing through hordes of foes.
A slaughterstone eviscerator's blades are of a size comparable to large greatswords.
Slaughterstone eviscerators cannot speak or make any vocal noise, nor do they have any distinguishable odor.
A slaughterstone eviscerator approaches combat with the uncaring and brutal precision that most constructs exhibit. When confronted with a large group of foes, an eviscerator uses its enhanced mobility to move toward the largest concentration of foes that it can reach and cut them down.
Lacking ranged attacks itself, a slaughterstone eviscerator is at the mercy of highly mobile groups with powerful ranged attacks. For this reason, dwarves and other races that employ slaughterstone eviscerators usually support them with a number of archers or spellcasters capable of striking down foes determined to fight from a distance.
Augment Critical (Ex): A slaughterstone eviscerator's adamantine blades are magically hardened and honed to a razor's edge. They threaten a critical hit on a natural attack roll of 18-20, dealing triple damage on a successful critical hit. The blades are not subject to effects such as keen edge that would further improve their threat range.
Enhanced Mobility (Ex): A slaughterstone eviscerator can move up to 15 feet in a round and still make a full attack.
Tunnel Fighting (Ex): A slaughterstone eviscerator has a limited ability to reshape its form to fir into a tight area. It does not take a penalty on attack rolls or to Armor Class when squeezing through a tight space. See page 29 of the Dungeon Master's Guide for more information on squeezing through tight spaces.
A slaughterstone eviscerator's body is chiseled from a single block of stone, much like the body of a stone golem. The eviscerator weighs at least 3,000 pounds. The stone must be of exceptional quality and costs 7,500 gp. Assembling the body requires a DC 20 Craft (sculpting) check or a DC 20 Craft (stonemasonry) check. Creating an eviscerator also requires four Large +2 adamantine greatswords. These swords are forever melded into the form of eviscerator and are destroyed if it is.
Cl 16th; Craft Construct, keen edge, geas/quest, haste, stoneskin, caster must be at least 16th level; Price 127,500 gp; Cost 67,500 gp + 4,800 XP.
Slaughterstone Constructs In Faerûn
Slaughterstone behemoths and slaughterstone eviscerators guard the kingdoms of the gold dwarves. The gray dwarves (duergar) build their own slaughterstone eviscerators and sometimes even ride them into battle.
