When fighting the 3 copies of Tropdoy, 2 of them stood close to each other in the water. I cast a lightning spell on them. The water was electrified and they were not stunned (they had no magic armor, but maybe they are immun). After beating all 3 of them the water remains electrified forever, at least until I remove it with battle stomp.
After combat I cast the same spell on another pool of water. This time electricity disappears after 3 turns, as it should be.
PS: When Trompdoy appeared the first time at the entrance, I attacked him before doing enything with the environment (like touching those crates). His skin became blue and his armor recovered after the hit, but combat did not start and he did not do anything until I killed him and got 2450exp (not sure about the value, not sure if this is intended.)
