Murrdox said:The spell simply grants a -2 AC to anyone buried in the mud, no matter how deeply. Since someone buried up to her chest will have more cover than someone buried up to her legs, -2 can't include the cover, since there would be two different cover modifiers.
So, you're right, it is the latter. I don't have the book in front of me so I don't know the AC bonuses for cover, but if you use 3/4 cover for chest and 3/4 cover is a +4 AC, anyone stuck in the mud like that would effectively get a +2 bonus to AC. If 1/2 cover is +2, then anyone buried up to the hip would not change her AC.
And yes! Remember the dam is worked stone! Of course, that stone on either SIDE of the dam might not be worked...![]()
3/4 cover is +7 AC and +3 save (giveing a +5 if mud givng cover)
1/2 cover is +4 AC and +2 save (giveing a +2 if mud gives a cover)
I still believe mud (and water) gives Concealment as it is not a solid object. Forest gives Concealment not cover. A Tree gives Cover not Concealment.
Mud would NOT stop a bullet.
