AD&D Advanced Dungeons & Dragons L1 The Secret of Bone Hill - TSR 1981

You find yourself in a tavern along the shore of the eastern bay. An aged Tabaxi beckons you to his table. "Good morrow! Care to peruse my wares, friend?" He pulls his cloak aside, revealing a vest with 100 pockets. You roll an investigation check. Natural 20! The pockets are impossibly deep, containing the Tabaxi's collection of tomes, parchments and scrolls. Each is quite old, sometimes smelling of must, mold or just stale air. "Ah, yes, these were left within a bag of holding for quite a long time, pardon the condition. Do please look closely if you wish to purchase." You roll an insight check. Another natural 20! The Tabaxi clearly wants to be upfront and wishes only for his customers to understand the condition of his wares. "And do inquire about bartering if you find interest in multiple items. This old adventurer has deals if you have coin."
