Nope. It's a big problem. My level 2 mage was thrown in prison. In order to break out, he took on 4 level 4 Magisters. At this point, I'd noticed that the combination of rain & lightning was effective, but I underestimated how effective...
I cast rain, covered the ground with water and used my lightning staff to attack one who didn't have magical armour. He was stunned. This also electrified the entire pool, but the ones with magical armour were protected.
Then I retreated.
All of the ones who weren't stunned advanced through the electrified pool, taking damage with each step. Finally, their magical armour was depleted, and the stun effect kicked in.
The stun effect wore off each turn, but all I had to do was use my electric staff again to electrify the water and stun them again. Repeat until done.
