Cast Sight doesn't stack with Augmentation
 

Cast Sight (Enchanter lvl 34) doesn't stack with Augmentation (Enchanter lvl 29). My best guess is that the stamina drain effect on Cast Sight is in the wrong slot, causing it to conflict with Augmentation.

According to Lucy's spell history for Cast Sight (and the similar spells, Shifting Sight (Enchanter lvl 20) and Bind Sight (Enchanter lvl 8) ), the stamina drain effect was in slot 2, and Augmentation's stamina increase effect was in slot 4.

Based on the different slots, I'd expect Augmentation to stack with any of these 3 Sight spells. Currently on p99, Augmentation stacks with Bind Sight and Shifting Sight, but not Cast Sight. So, if nothing else, something seems inconsistent between the Sight spells.
