Tomorrow I'm going to try not to TPK the party with an ambush scenario involving draconic sorcerers.
The scenario will hopefully unfold something like this: the PCs walk into an ambush, four 10th-level Draconic Sorcerers invisibly hidden in the trees around a path through the forest. One casts stinking cloud, another casts black tentacles, and the last two unleash a 10d6 acid breath weapon.
My question is this: Assuming the black tentacles' grapple check surpasses the CMD of each player, do they get a reflex save to dodge the breath weapon if they are nauseated and also grappled? Even if the grapple fails, do they get a save?
