My argument about all SoD effects.
I figured that would come up.
Hrm, my character, in order to be targeted by a cdg attack, needs to be either:
a) rendered completely helpless magically
b) beaten unconcious through non-lethal damage
c) asleep
Now, is it good encounter design to have an invisible thief sneak into the character's room, without any warning, and cdg him in his sleep?
Because that's what putting a medusa on a random encounter table basically works out to.
Now, I know you can manipulate the situation so that the player always has the ability to know that the SoD encounter is coming and can react accordingly, but, to me, that's too heavy handed. It's pretty obvious what's going on when every stranger I meet suddenly goes out of his way to mention that there is a specific kind of creature in that area. Never mind the fifteen other kinds of creatures there. They might or might not get mentioned. But every SoD creature will always be known.
Me, I'd rather just lower the lethality and then treat SoD creatures just like any other creature. Much less work for me as a DM, much better encounter design, and a much better designed monster that is no longer a one trick pony.
Makes me perfectly happy.
