98 SPARRING ROOM. Nine murmillones are practicing combat here. They are very careful to stay at least five feet away from the central pool, which is somewhat unpleasant smelling with rotting vegetation.
9 Murmillones (AC 7; MV 12”; F2; hp 12 each; #AT 1; D Short sword +1 due to strength; XP 71 each)
Each gladiator has 2d10 gold crescents. If the murmillones hear the bell from Room 95, seven will go there to help repel invaders, while the other two will alert other murnillones in other rooms.
The reason the gladiators avoid this pool is because it houses a shambling mound, which will form itself and attack anyone who comes within five feet of the pool edge.
Shambling Mound (AC 0; MV 6”; HD 9; hp 41; #AT 2; D 2-16/2-16; SA Suffocation; SD Partial magic and spell immunity; XP 2092)
The pool is ten feet deep and the water is very murky and choked with vegetation. At the bottom are 2673 copper pieces, 764 silver spanners, 964 gold crescents, and a chime of opening.
A reasonable supply of weapons found in the Player's Handbook can be found here, along with wooden mockups used for practice.
