A wonder is an unusual spellcasting focus such as a sacred flower that never wilts, a prismatic crystalized skull, or a polished burl that whispers with the language of the trees. If you lose a wonder, you can replace it as a ritual that takes 10 minutes and requires 5 gold worth of rare materials. You must be able to cast ritual spells to restore a lost wonder in this way. When you do so, any previous wonders created this way are destroyed.

These large and imposing tomes can function both as a spellbook and as a spellcasting focus.

Focus tattoos draw on a bearer’s own magics, and must be attuned like a magic item in order to function and require an attunement slot (information on attunement is in Trials & Treasures). When you cast spells with a focus tattoo in this way, you must briefly touch your focus tattoo with your free hand.
