To Damian, slight temperature changes barely bothered him anymore with his endurance stats being through the roof.
Without him being present to see the runic circle forming, when civilians activated the runic replica spell device with their own mana, the IDs could not be collected. What if he.. just collected liquid mana from everyone and made environmental mana using replica spell runic devices?
That would exclude him from the basic ground-level procedure of registering an individual in Sanctum's database. Not just the mundanes—Damian could use the aura extracting spell for all people; both mundane and Pathfinders.
The shelf life of liquid mana was not too long though; the denser the aura, the longer it lasted. But he couldn't expect mundane people—especially little children and elderly people—to be able to give more than a little aura at a time. Converted into liquid mana, he could expect the worst shelf life of around seven to ten days.
