As the title says, I am looking for a mod that would add spells that utilize Earth and Water elements. I don't recall if Midas Magic adds such spells, but I am also looking for other spell mods that accomplish this, and if they do other stuff(Like revamp the magic system) that's fine too.

I know Midas Magic adds quite a few water spells. Not sure about earth ones. I'm not sure if you're familiar with Midas, but there's a whole plane dedicated to water, so I'd check that out.

what exactly do you mean by earth? terraforming? or just earthy/woodsy themes? for the former, i can't think of one; however, i know LAME adds a variety of earth-themed summons like rock, glass, gold, and ebony golems.

Yeah I am very familiar with Midas, I mustn't of paid as much attention to the sea realm last time I played it.
And using the earth to harm opponents, from propelling rocks, to an earthquake.

Midas has both of those... an Earthquake spell and several that that attack with rocks. I find the Midas Crushing Stones spell really useful because it does trap damage rather than magic damage. It's a life saver for a mage character going up against an enemy with high magic resistance/reflection.

Yeah Midas definitely sounds like the way to go here. It includes spells for all of those things.

Yeah Midas is your best bet. The water spells are a little on the meh side (except for the burst) but the earth related spells are excellent and quite powerful too.
