The spell component recharging on rest is a really cool update. Spell components have long been tedious and annoying (before someone chimes in and points out how much worse mundanes have it, I would agree with you, but that's not what this thread is about!)
My feedback is that I think Pale Masters got overlooked in this update. Pale Masters can cast Epic Spells once they reach level 15, even if they have limited other casting abilities (such as the case with bard/PMs for example); they even get two epic spells for free. Therefore, I suggest they should qualify for the "Arcane spell casters who can cast 7th circle spells and above" requirement, but currently, they do not receive spell component charge refreshes.
If the goal of this update was to lessen the tedium of playing spell-component-consuming classes, then I believe this is an oversight worthy of correcting, as since each of the Pale Master's signature spells costs a whole component to cast (Mummy Dust, Epic Dragon Knight, and (usually) Epic Mage Armor), this class can chew through components pretty quickly. Because Pale Master is a prestige class and rarely taken in multiples of 9, I would also put forward they should add their base arcane class to their total level in regards to this perk.
Thanks for your consideration.
