How does the lack of milestones affect the Artificer, whose Arcane Empowerment ability starts with one use, and gains more with each passing milestone in a day?
For the special AP option, it says you spend one AP forever. Does this mean that each day you start with one AP instead of the normal two? This essentially means that characters can only gain a max of 2 AP per day, no matter how many encounters there are in a day. Of course, the same goes as normal, meaning a character can only gain a max of 3, so if there's the chance of more than 3 encounters, we need to be extra careful of whether we spend AP in a given encounter. Not that I'm in any place to complain, but that seems fairly restrictive.
Can an Innate magic enchantment be Disenchanted from a person, as normal for a magic item, resulting in 1/5 the effect's value in Residuum?
Also, I'm sure you're getting around to it, but who in your world would be considered the prevailing god of magic and the arcane? I imagine that would be the primary deity of Il Sanaria, and my character's deity as such. However, being that magic isn't as prevalent in the world, is there a god of magic at all?
