Crystal Spear

Obtaining

 * Found in a chest in Sellia Hideaway (Caelid).
 * From the Sellia Hideaway site of grace, progress north through the cavern while staying on the top level and continue into a tunnel past the Stake of Marika. Once you reach another section overgrown with crystals, look north for a corpse behind the crystals holding three Preserving Boluses. Strike the illusory wall next to it to reveal the chest.
