Nebulism
From Unusual Haunts
Nebulism is the art of calling the mists around Penwick Gorge to you, to help or harm. There are several ways of doing this:
Solomon Scott's Mist-Calling Experiments: Once per event, you can call up a field of mist in a 5-metre radius around yourself; within that field, other nebulism abilities can be re-used once every 10 seconds. If you leave the field, it dissipates; you can create another by opening a jar of mist.
