Locking Spellbook

Dalelands Wares
The wise wizard keeps a copy of all their spells safely tucked away in case of disaster. We supplement our spellbook with a trusty lock secure enough to dissuade curious goblins.
This 100-page leather-bound tome can be used as a Spellbook. It is closed with a lock that comes with a key. As a Utilize action, a creature can try to pick the lock using Thieves' Tools, doing so with a successful DC 15 Dexterity (Sleight of Hand) check.
