Welcome to Gumnut!
Loot!Thatâ€™s both an answer and an exhortation. Yes, 13th Age is all about the story and the awesome action, but weâ€™ve all got a treasure-hungry munchkin inside of us, and itâ€™s time to let that grubby-fingered kid out to play.
The Book of Loot is full of more magic items to be found, stolen, given as rewards or otherwise looted by the player characters. Weâ€™ve also thrown in a short chapter on ways to make mundane treasure more interesting, and a selection of new one-use magic items.
