The last circle
The enemies camping on the floor above , were wizards , hence charging head on would only mean being bombarded with a ton of spells.
Nero asked Rudra , if he should send up a swarm of undead to take the brunt of the damage , while he and Neatwit could charge in later , to take the enemy down.
However Rudra did not want to use such means , the mana recovery potions in the national battleground were far and few. And the team only had access to one intermediate recovery potion . summoning the undead would surely drain Nero ' s mana by a significant margin.
Instead Rudra wanted to try something else , something creative to handle this problem.
He instructed Neatwit to rush in from the stairs , exactly 3 seconds after he heard the window breaking.
