Wolfe settled back into his chair after a quick meal and immersed himself in the study of all of the things that might go wrong with an improperly attuned advancement, as well as the side effects of having his Pentacles formed before he became a King.
The first list was exhaustive, with tens of thousands of examples through history, but the second was actually quite simple.
The advancement would have the same effect that the Witches' Saint Rank advancement had upon the Pentacles, only stronger with more mana flowing, and it would all be tinged with Wolfe's own particular mana signature.
Normally, that would make it hard for the Pentacles to absorb, and it could cause some aura damage, or even physical damage due to incompatibility after the Kings had adjusted themselves to better match the world.
However, Wolfe had already learned how to attune that mana to the Pentacles, so they could absorb it more smoothly.
