Vapor Eruptio

Synopsis
This spell uses water, fire and wind in that order to compress boiling water into a small orb-like mass that in a few moments will make steam and water burst forth with extremely high pressure.

How it's Done
The user creates water, then uses fire magic to heat it up, then uses wind magic to gather it and compress it at high speed. their are two methods to achieve this, do it as stated before but this requires lots of magical power and concentration however it is less complicated. Using alchemy achieves the same spell however it has less power but allows you to conserve power and use the spell repeatedly.
