Great! Thanks for the response on this. You guys may beat me to it, but I was hoping to post the lists I came up with to hopefully contribute to the increasing of spells in general. I'll try to get as much done this week as I can and post the mod in the hopes that other folks can try it out and provide some balance comments.
One of the spells I would like to create is a tactical spell that modifies a tile to damage an enemy or friendly unit when the unit enters the tile. Anyone know if this is possible? Obviously we can tag effects to tiles, as the Rockslide spell in the Earth spellbook shows, but I haven't been able to figure out if a damaging effect is possible.
Has anyone tried making a tactical summon unit spell? I'm thinking along the lines of the MoM Phantom Warriors spell, that summoned a unit of magical troops for the duration of the tactical combat. I'm trying to work on a revamp of the spell lists for Fire, Air, Earth, and Water. Having tactical summons available would greatly increase the options.
