Generic fantasy RPG wizards, not EGS wizards. Though I suppose an EGS wizard could learn such a spell. It's just not a given.
Thank you all for the questions! I have a few comics written already, but I'm still sorting through all the questions, and I'm sure some answers will raise further questions.
I wanted there to be enough clutter in the background that Amanda and Lisa would not appear to simply be in front of a wall with a pattern, so this wound up basically being a Skyrim dungeon in which you can just find potions, treasure chests, and sacks of potatoes in random corners.
