Nope ... just steam. Youl have to electrify it later ...
Question tho: Was anyone inside that fire/rain? And if so ... what artefacts they were wearing?
Got electrocuted as I moved party across the fire to the left of the burning inn. Created a water surface, moved Shadowheart (wearing her standard mail) myself (sorc) , Gale and Wyll across. All got electrocuted. No character was wearing anything that should auto-electrify water surfaces. Hasn't only happened once, though. Has happened in multiple playthroughs.
