Though Frost coughed up 30,000DP for the assassin prisoners and an additional 20,000DP for other who had been patiently waiting to serve their new lord and master he still felt it was worth it.
With a flick of his hand one of the scrolls transferred over by Agar appeared before him. The parchment was made from sturdy beast leather and the runic inscriptions made from the blackest of inks, the thing radiated death energy.
3rd circle spell [create undead] by imbuing the scroll with mana Frost could cast a spell not of the ice element though with less potency than an actual necromancer. If used on a peak C-rank corpse a mid or upper D-rank undead monster could be created. Definitely not worth 6200DP but at least the created monster like those individually summoned had the capabilities to rise through the ranks plus the main objective was to ensure he got the most out of his prisoners pathetic lives and deaths.
