Ok, now for the new spell ideas. I think the lack of any spells to change the nature of the battlefield in tactical combat is a glaring lack, much like the 0 level spells were. With that in mind I humbly submit my ideas for 4 spells to change that, the idea being one per element and having them be 3rd level spells. Please note the balancing on these will be rather important, getting the AI to use them intelligently will probably have to wait until we get the modding czar and see what they are doing with tactical combat. Right now creating high value content that we can add hooks to later seems the most efficient use of time to me, and in that spirit.
Battlefield Tacticus Magica:
