The spears were struck on the ground forming a defence line. Many low levels of undead were afraid to move towards it and were instantly brunt as they came near it.
The spears persisted for some time before disappearing.
The undead who were Epic rank and above were affected a bit even so they braced themselves trying to breach through it.
For them, Alex summoned the swords of light and passed them to the guards and asked them to use swords against the undead.
Seeing their sceptical look Alex spoke"I am going to be a Holy son soon. The light sword contains sacred blessings of light granted to me by Goddess Rebecca. It will persist for three minutes but if you pour your mana into the sword, it can last quite longer"
Alex's words brought them some relief and as they wielded the sword of light, the undead became restless as the light could erode a part of them.
As the guards poured mana into the sword, it glowed more vibrantly.
