*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 separate from each other, . One use of freeze will affect the above and must be frozen separately using two different uses of "Freeze"below ground tiles.
*You may not use the "Erupt" ability outside of your own kingdom.
