Prior set with Netherite Healing Wand results in a Healing Power of 6, but the Priest set with the same wand results in a Healing Power of 7. Considering the Prior set requires some rarer materials, this seems unintential. It's easy enough to configure though.

Hi,
While this is not great, it isn't a huge problem. Wands aren't meant to be primarily used weapons, their main purpose is to teach players in general how basic spell casting works, and serve as early game weapon options.

Armor pieces can be reconfigured give different bonuses, for example +2 Healing instead of +25% in case you prefer that.
Also Prior armor set does have additional valuable stat bonuses (as the default config).
