We need a level 1 scouting spell.
Scout units are terrible and level 1 spells are underwhelming at the moment. But we want to keep them somewhat weak in combat to prevent sovereigns from being overpowering. I propose a level 1 scouting spell for Air. Something that lets you pick an area and then bling you can see what's there. The air sphere could use some help as it is anyways.
As a secondary, related idea, water might get a higher up spell related to scouting out the water. Perhaps, revealing all water tiles on the map, which would be useful just to get a general lay of the land.
