Tales of the Valiant Players Guide (pg. 127)
Choose one of the eight schools of magic: abjuration, conjuration, divination, enchantment, evocation, illusion, necromancy, or transmutation. You gain these benefits:
• When you cast spells of your chosen school, your spell attack bonus and spell save DC are both increased by 1.
• If you use a spellbook to cast your spells, the gold and time you must spend copying a spell of that school into your spellbook is halved.
• When you spend two or more sorcery points while casting a spell of that school, you regain 1 sorcery point at the end of your turn. You can select this talent multiple times, selecting a different school of magic each time.
