This spell is very useful and it is advised to keep it on the skillbar. When there is big need in energy for the mage, Inspiration should be used. Energy can run out pretty quickly by using high-cost abilities, particularly group attacks. Although it can replenish the entire mana pool in 3 turns, it is not advised to do so, as the mage is comparably slow and each skipped turn may be detrimental to the group.
