Legend
The book generally seems written more true to 5E spell mechanics than previous books, with Spirit Guardians, Concentration, Divine Smite, Dissonant Whispers and Augery all really matching their DND mechanics in ways I don't remember previous books doing.
Spell use is rare but previous books they used things like stoneskin and haste which were consistent with the game descriptions.
The young elf girl he spared on his raid in homeland used a spell combo to try and kill him later.
