Eldrian was actually surprised by this, thus far he had not really felt that magic was all that strong. Sure it was very useful for him, a High Elf. He could actually control his spells, unlike all the other mages he had met. If not for this, he felt that magic was simply too limited, especially at the start. The spells were generally weak and had little adaptability.
Seeing the effects of just a Tier 3 mage against the undead, Eldrian realized that it might ramp up faster than he had expected. Having only felt Tier 5 and above would really be able to use their magic effectively in combat. As had been his experience this far, and was shown with the mage being nearly hopeless if not being defended.
Then again, it might just be due to the enemy. Undead were naturally magic born, and as such, they might be weaker against magic. Something that held true this far.
"Thanks for the save." The mage said as soon as he and Eldrian finished of the last undead.
