Forgotten Vault of the Lost Arcanist

After navigating a series of complex mechanical traps and twisting corridors deep within the dungeon, the party discovers a long-sealed vault once belonging to a reclusive arcanist. Though no monsters guarded this chamber, the vault contains carefully preserved remnants of the arcanist's research and personal collection — items that speak to a life dedicated to magical experimentation and arcane craftsmanship. Treasure here is balanced to suit a level 4 party, offering useful crafting materials, minor magical reagents, and small but valuable gemstones that any adventurer could easily trade or use to craft enhancements.
