So, back to the actual conditions. Mainly I'm looking at them from a balance perspective. I'm going to tone down the Placid one to remove the charm element; I'll just go with no aggressive actions.
I went with Infuriated in the end, but that sounds more like 'annoyed' than 'rage-filled'. The effect I'm after is somebody who bursts into a violent rage with little to no provocation, perhaps due to some kind of psychosis or psychic effect. Google tells me that "intermittent explosive disorder" is a thing, but that's not a great name for a condition. Plus I don't want to veer to close to actual psychology, as this is clearly fiction.@Morrus - Howabout Incensed for Vexed? Sounds more angry and less confused, IMO.
