*Cave walls that are under the tile that is erupted will change into lava walls. This includes ore veins. These lava walls can be changed into regular cave walls with the freeze ability.
*The resulting lava tile above-ground and lava wall below-ground are not selectively separate from each other. One use of Using freeze above-ground will affect freeze both the above surface tile and lava wall below -ground tiles. However, using freeze on the lava wall will not freeze the lava's surface tile.
*You may not use the "Erupt" ability outside of your own kingdom.
