From the entrance of 'The Sandy Grave', head right and navigate through the quicksand areas. You'll need to use your double jump and careful platforming to avoid falling into the pits. The 'Sanctuary' spell is located in a hidden room in the upper-left section of the painting. To reach it, you'll need to find a breakable wall near a large quicksand pit. Use Jonathan's Axe sub-weapon or Charlotte's offensive spells to reveal the path. Once inside, defeat the enemies and claim the 'Sanctuary' spell. This spell is crucial for removing curses, which will be important for an upcoming boss battle. Practice using it to understand its range and casting time.
