Blessed

Collect all 45 Charms, then buy Salubra's Blessing - the special charm she only offers once you own every other one. A full-completion hunt: charms are bought, found, won from bosses and handed out for quest/Grub rewards. A few are DLC-gated - notably Grimmchild from the Grimm Troupe questline (see Grand Performance / Ritual) and Carefree Melody if you Banishment instead. Grab the lot, then visit Salubra for the blessing. Contributes to Pure Completion.
