Earth Magic

Could increase mana regeneration from 1 to 2
Create water spells and fix the earth ultimate (you can't see the skill working in practice)

You could make a whirlpool, rain, throw water, create a sphere of water that traps enemies and drowns them, a wave... There are several possibilities for magic with WATER alone that can cause damage and interact with the environment, flooding, putting out fires and petrifying magma like water does.

Please do water magic. It would be amazing if they were well made and just water (no ice)

this is actually cool you should stick to this with only one item you can use all the skills but can you just make it that the magic book gets stronger when leveling up cuz if too op in early game

a function for infinite mana would be cool
