Borrow an Arcane Spell

Concentrate Exploration 
Source Core Rulebook pg. 241 4.0
If you’re an arcane spellcaster who prepares from a spellbook, you can attempt to prepare a spell from someone else’s spellbook. The GM sets the DC for the check based on the spell’s level and rarity; it’s typically a bit easier than Learning the Spell.

Success You prepare the borrowed spell as part of your normal spell preparation.
Failure You fail to prepare the spell, but the spell slot remains available for you to prepare a different spell. You can’t try to prepare this spell until the next time you prepare spells.
