The Mage’s Toothache

It was the ancient mage’s last tooth. And it hurt like hell.
The toothache remedy potion bottle was empty, and all of the pain spells had verbal components.
His apprentice, not yet skilled in the art of Relief enchantments, was drunk at the pub when a party of adventurers overheard him complaining to the bartender.
“We can raid the tower and free this town of evil,” whispered the paladin.
The cleric and thief agreed, and made their way up the mountain.
Unfortunately for them, the mage’s wands were all point-and-shoot.
He left the cleric alive long enough to heal him.
