These empower the caster's allies, protecting them with sorcerous wards and magically enhancing their fighting prowess. The following applies to augment spells:
The target must be a friendly unit.
The target does not have to be within the Wizard's forward arc.
The Wizard does not need line of sight to their target.
The target must be within the spell's range.
Wizards can target spells at units engaged in close combat.
If a Wizard casts a spell that targets them and the unit they are with and then leaves the unit, it will only target them. If they subsequently join another unit, or rejoins the unit they have left, while the spell is still in play then they will benefit from the spell.
