I have a question that I need of your thoughts on. If my magus turnes pices of stone that where recently a part of a mountain into water with muto magic. And then pour it into a mould, what would happed when the spell wore off. Will it turn back into pices of stone or would it form into a solid block of stone. The question is some what related to the essential nature of the stone and how it relates to muto magic. Muto magic canÂ´t after all make some lasting changes without the use of raw vis.
Either result would give interesting opportunities for a crafty magus or maga (read Verditius magus). If the pices of stone turnes into a solid block then the spell could be used to create exelent quality building blocks for a covenants house building or for sale, thus increasing the covenants profits.
If the stone turnes back into its original shape a remains as pices of stone then they could be used in mining. Use perdo magic to create a long thin hole and pour some liquid stone into it. When the water turns back into stone the mountain whould crack. The effect would be the same a the traditional mining method of heating with fire and cooling fast so the stone cracks. With this incresed speed mining method the covenant would rapidly increase it profits, less cost for fuel and less risks.
Awaiting your thoughts
