Endless Grimoire

When opened, this grimoire has unlimited
pages and eagerly transcribes spells. It has no
limit to the number of spells it can contain.
You gain a +1 item bonus to checks to Learn
a Spell when transcribing into the grimoire.
During daily preparations, if you can prepare
spells of the appropriate level, you can prepare
an additional 1st-level spell due to the
grimoire's nature.
