Rotting Grey Robe
A pile of cloth lies on the floor, rotten and stinking of disease.
Armor class is 10-12. 'plague ' continuous Modifies strength by -2 continuous. Modifies mana by 70 continuous.
Apart from the penalty to strength, this robe also gives permenant plague. As its mana and AC are identical to both the Pitch-Black Robe and the Red Velvet Cape, it is much better to go for one of those - not to mention a lot easier to get either of them.
See Pestilence for more information.
