I\'d like to be able to create new spells, maybe even on the fly. Spell modding / combining could be used for this so the spells can\'t become too powerful. Like have a _huge_ list of elements / options / effects that can be chosen from for the new spell. Mana cost and spell complexity will be calculated from this.
Also, I\'d like to see all spells (and skills) work on everything. I hate mugs or trees that are totally immune to acid or fire spells or something. I\'d like to be able to drill holes into walls / mugs / whatever at random places. Or freeze the torch on said wall with an \"ice\" spell. Things like this. Use the \"push\" spell to break the bar that supports the roof of the building, making it at least unstable. Or use a \"float\" spell on one or more plank(s) to get accross a canyon.
