Damian kept 150-plus mana threads attached to the ten steel pillars as he flew towards other Legendary-class monsters which had closed in. The thick mana spreading into the atmosphere had powered up all the cannons placed atop the giant Ice Wall.

Realizing what had happened, Maelor and Alex left their three laser cannons and shouted orders for the pigmen soldiers to spread out and occupy one cannon per pigman. There was a lever built in the middle of each laser cannon, powered by Damian's mana cloud.
At first, they had all questioned the extra step Damian had taken to add it to every cannon he built. It simply launched the laser burst spell when the inscribed runic circles fully gathered the environment's mana. For multiple pigmen powering it, there was no use for a lever—they had to activate the spell directly.
