Trying to transform Saintess Charlette's two hands into the sun is not an easy task.
With Mohe's current abilities, without reclaiming the essential part of alchemy, her actual alchemical skills are quite limited. Charlette's hands can't be considered top-tier material, as Charlette can regenerate such arms at any time, but their symbolic meaning is entirely different.
In divine art, there is something known as the "Silver Hand," said to "heal all things in the world." This skill is the most commonly used among high-level priests, and thus, their arms are imbued with this healing trait, possessing a portion of "divinity." Of course, they rarely use this divinity themselves. It can be said that most priests cannot even realize this aspect of divinity, Charlette being an exception, naturally.
