Air Dome

[Agema]

Mm. I think stacking air domes would have its uses (were it not an exploit).

When facing an air dome, fire cheap chaff 2-gem spells at the same time as a few big damage spells. 3 Murdering winters would cost about 100 gems and have just over 50% chance of no effect. However, cast two MWs and 15 chaff. That's still spending about 100 gems, but there's a very good chance the 2-gem spells will destroy the air dome before either MW hits.
