The Ice Prison, as an aura-type skill, doesn't deal high damage—only around 500 points per second. However, its real strength lies in the summons it creates and the continuous, mindless control it provides. As long as there's enough mana and the opponent lacks powerful anti-control skills, they'll be frozen continuously.
Orson's eyes flashed as he adjusted the range of the Ice Prison aura to two kilometers, with a precise mana consumption of around 1000 per second. While this wasn't the maximum output of the aura, for most players, just keeping it up for two seconds would drain their mana completely. But Orson had over 50,000 mana, and with the 2% mana regeneration from his [Power Sanctum Shoulder Plates], his consumption and regeneration were perfectly balanced.
Within that two-kilometer radius, Orson was the undisputed master of the domain. Coupled with his five-kilometer range, he was essentially a mobile, chaotic freezing turret.
