Tom’s ability to find an accursed master on the mortal plane and open a portal for a demon to go their under no wards at any time or place will likely be in great demand. Frankly their is little a demon would enjoy more than an option for that. Look at what Tizzy or any demon other than Tom does when they run into their master whom is unprotected and unmolested. They mess them up. That is a skill that could be used greatly for demonic profit as it lets one kill the master and loot their stuff. Wizards tend to be rich.
