When the magic is implemented, i would love to see any spell that had any effect on resources, since its a "farming game", some examples are ore generation (at high mana cost), overclock furnaces/forges/etc, a freezing ray (or smth like that) that could freeze water to make temporary bridges (mana regen should be a thing, because the player could softlock himself, like going to a island without enough wood to make bridges and without extra mana apart from the mana used to create the ice bridge, and waiting till the ice bridge is gone), spell for transmutate ores into gems, a spell that would give temporary speed to your pickaxe and hammer, etc.
