My partner and I have been playing a pair of characters in online multiplayer. Originally both had a occult damage concept.

Recently she respecced to make an oracle of the trinity concept caster with a heavy emphasis on DOT damage and reduced direct damage.

After she made this switch I noticed I was getting 12 stacks of shocked and burning intermittently while doing expeditions. No, I am not running fatal pact on my character where I would somehow be giving myself ailments.

She does not seem to be getting any kind of unusual ailments on herself.

Often the magnitude of these double stacked ailments is so severe my character just degens to death during expeditions.

With some further investigation and testing we found that this no longer occured if she disabled the reprisal rune for thunderstrike.

This would suggest reprisal is somehow striking or spreading ailments to allies in mutliplayer.
