New items introduced in Legends. The categories are Survival, Tempting, and Warding. Survival Charms help the player endure more hits before dying which is why they are useful in Noble boss fights. You can get them in Jublife Village from an NPC named Charm Lady LucilleArcanine's the only one that gave me actual trouble. I lost ot Electrode the first time by dodging the wrong way but Arcanine's lighting the arena on fire was difficult to deal with since it tends to strand you exactly where it's going to charge at. The others I all beat on the first try. Haven't gotten to Arceus itself yet though.
And, uh, sorry if this sounds dumb, but what's a charm?
