I was skimming through AD&D Ruins of Undermountain, just to see how it compares with 5E Dungeon of the Mad Mage, and I stumbled upon this:
Old Xoblob’s shopThe shop is named for the stuffed, eyeless beholder that hangs from the ceiling inside. Aside from being a curiosity in itself, the beholder conceals a hired wizard who can fire a wand of paralysis out of the dust-covered eye tyrant’s mouth.
I chuckled to myself when I read this. Just picture the poor guy, hidden in a stuffed beholder, twiddling his thumbs ALL DAY LONG!
Adventurers won’t steal from Xoblob’s shop so easily.
Dandalus will trade with whoever comes through the gate. He makes no enemies, he merely charges more for services to those attackers or doublecrossers. Dandalus always takes the following precautions: he wears a ring of spell turning, a ring of free action, and a greenstone amulet; he always carries two potions of extra-healing, an elixir of health, two iron bands of Bilarro spheres, and six beads of force in his pockets.
The shopkeeper will charge more for services to attackers…
A magic shop, a wizard bored out of his mind and a shopkeeper that EXPECTS to be assaulted by his usual clients…
