“Why won’t you attack me like you mean it?! Are you making fun of me? Lava Swamp!”
“Freeze! Fire Resist! Owww, that’s hot…! I don’t want to destroy you any more than I want to quit my job! Liches are very good at resisting magic! I’ll endure anything you can throw at me until you have no choice but to give up!”
The rocks around Wiz’s feet had turned into a molten swamp; she chilled it with Freeze, then used another spell to heighten her resistance to fire and help her escape.
