Lost Stoneskin is such a cool spell and really fits the whole rock aesthetic of white mage. When I first saw it in Bozja I thought "oh wow this reminds me of white mage and conjurer". Which got me wondering, wouldn't it be cool if in 6.0 Stoneskin became a spell on white mage that they can use in any content? It fits the whole conjurer vibe where you're conjuring rocks and water and all that but the rock can also be used for protection instead of just damage!
