Scarlet Rot Contagion Sharp-Edged Dice

Easy there, tarnished.  It looks like you've spent a little too much time in Caelid.  Even your dice have taken on the effects of the Scarlet Rot.  I can see that there are 9-dice in your set, and that extra D20 bears the insignia of Red Star Dice.  No worries.  I'm sure I've a potion that can cure that right up.
