Osric lost more than half of the forces he took with him. Apart from that, he also lost the dummies who agreed to come. Even if Layla had agreed to let him take those dummies, it was because she believed he would take good care of them. Now that they were destroyed, Osric was truly mad.
They only had a couple of hundreds of those dummies, yet more than twenty of them were already destroyed.
Truly, the result of this battle was such a disgrace to Osric. He was a Legendary mage, yet he failed to prevent such a thing to happen— not to mention, he actually fell to Kyran's trap and could not free himself from the latter's Containment Array.
This was truly a disgrace!
Still, although Osric thought this, others would disagree. His loss might be disgraceful if his opponent had been a normal mage and not the new Dark Sage. Frankly, the result could be considered predictable given Kyran's seemingly omnipotent Void magic.
