If you feel like going through lots of ingredients (perhaps with a save-load cycle) mixing potions at random will reveal more effects than just eating raw samples.
Slave? You mean something beyond the normal daedric quests? Doesn't sound too tempting to become a slave. Especially of a Prince of Oblivion. The quests, at least the three I've tasted so far, are more involving and longer than those in Oblivion.Has anyone become a slave of a daedric god yet? I turned down my only offer so far. Had to kill two daedric minions, but then it wouldn't let me loot their armor.
