Tobyn's Codex of the Inner Earth

Spellbook, uncommon

This sturdy 6 lbs tome is made from interlocking brass plates with acid-etched High Dwarven text. Equal parts thaumaturgical treatise and practical spellbook, this book contains the foundational occult knowledge and spellcraft considered essential for Clan MakDruun’s arcanists, artisans, and priests. The final plate is a brief biography of author Tobyn Murn MakDruun, a noted wizard, wonder worker, theologian, and tutor to three generations of MakDruun Lord Intendants.

If you take 5 minutes to consult Tobyn’s Codex of the Inner Earth before making an Intelligence skill check to recall lore related to dwarf magic, dwarf crafting, or the elements of fire and earth, you gain advantage on that check.
