Odimasadra has weak loot for the monsters you fight. In total you fight 2 frost atronachs, 2 daedroth, and a storm atronach, all in a tight space with the final battle being both daedroth and a frost atronach all at once. In terms of loot, all you get besides a single exclusive potion is 2 very common books, a weak healing amulet, a single piece of gold, and a redware bowl. Compare to any other daedra filled location, like a ruin, and you usually get better stuff.
