||This slimy entity appears as wet stone or sedimentary rock, allowing it to easily blend with natural surroundings. It resembles a puddle 30 cm (1 foot) wide and 1.5 metre (5 ft) long for every full 6 points of SIZ. The largest reaches SIZ 18. Regardless of length, the ooze is about 15-20 centimetres (6 to 8 inches) thick.
Grey ooze is also completely resistant to most offensive spells, including both cold and heat; however, it takes full damage from lightning. Weapons inflict only minimum possible damage, including that produced by the attacker’s Damage Modifier.
However, killing one of these creatures is difficult without electrical damage, since it constantly regenerates damage inflicted upon its goopy body by physical weapons, healing 1d3 points per Round.
Grey ooze is able to slowly flow across the ground, very slowly, so much so that adventures aware of its presence can usually circumvent it. They are able to digest all they are able to dissolve, and can sneak up on unaware victims using their near-silent mode of locomotion.
A grey ooze is highly corrosive, able to eat through steel and flesh in a matter of seconds. When attacking, a grey ooze strikes like an oily black snake and applies its acid damage to whatever location is struck.
*Onset time*: Instantaneous
*Duration*: Acid continues for 1 Round after contact ceases.
*Conditions*: As soon as the acid slime touches a victim or a piece of equipment, it begins to eat away at metal (Armour Points in the case of armour) and flesh at a rate of 1d6 points per Round. It does no damage to wood or stone, however. This damage is applied every Round the victim or their equipment is in contact with the acid, plus 1 Round thereafter. Therefore, striking the creature with a sword, for example, will cause the blade to take 1d6 damage in the Round it hits, plus another 1d6 damage on the following Round. Crushing weapons such as maces, clubs, etc., have a percentage chance of splashing their users equal to 5 times the damage rolled with each impact. This splash damage does 1 point of damage to 1d3 hit locations and functions as above.
*Antidote/Cure*: There is no known counter agent for the effects of the acid short of washing it off and healing any damage.
