Acid

Caustomancy is a dangerous spell school. An artificially made school born from its Hydromancy brother. Caustomancy is made to speed the process of degradation, and corrode any defenses; a strong but dangerous power.

__

Learning Acid While a caster is studying as a down time activity, they can replace the Ice, Fire or Lightning schools they know with these schools.

__

Corroded Status. Corroded is an effect that stacks the more the effect is used on a target.

__

Chemical Reactions. Acid can easily fuse with other elements for devastating effects! If Eroded Ground and other similar effects interact with fire, the corrode explodes! The damage of the Fire spell is spread. If Ice is hit, it turns into ice and is difficult terrain, if lightning is hit, the area is Charged.
