What Doors We Open

What Doors We Open is the culmination of Aravashnial's research. Before he was captured, he performed a 1-minute ritual to erase his spells from this book and then hid it at his campsite to prevent his demonic foes from learning too many of his secrets. A spellcaster can transfer their own spells to this grimoire using a similar 1-minute ritual. When a spellcaster prepares their spells from it, they gain the ability to Activate the grimoire until their next daily preparations and gain a +2 item bonus to checks made to Recall Knowledge about demons. A grimoire's benefits apply only to spells cast via spell slots. No one can use more than one grimoire per day, nor can a grimoire be used by more than one person per day.

The inside back cover of What Doors We Open features a realistic depiction of a bejeweled door set in a stone wall. When you Open the Door Within, you open that door to reveal an extradimensional space that otherwise functions identically to a Spacious Pouch (Type II).
