ToME: the Tales of Maj'Eyal

Aehter Permeation:

1) "In effect all your resistances are equal to 66% of your arcane resistance."

Does this mean that the prodigy will actually lower any resistances that would've been higher than 66% of my arcane resistance? For example if I have 60% fire resistance and 60% arcane resistance and then take the Aether Permeation prodigy, will it reduce my fire resistance to 40%?

2) Does it check my arcane resistance before or after adjusting for resistance cap? For example if I get 90% arcane resistance from my Disruption Shield and my cap for arcane resistance is 70%, will Aether Permeation give me 60% resist all (66% of 90) or 47% resist all (66% of 70)?

3) Can you even get this if you aren't an Archmage? In order to avoid spoilers a simple yes or no will suffice.

Revisionist History:

1) If I understand the description correctly, this allows me to essentially save the game and then in the next 10 turns I can use it again to load the save I just made. Is this correct?

2) The thing in "D" counts as time travel, right? (Being vague to avoid spoilers.)

Aether Permeation
1, yes
2, yes
3, yes
Revisionist History:
1, yes
2, no, time travel means split the timeline. 'D' things is for Temoral Form

Thank you very much for the answers. Although the second questions was a "before or after" question, not a "yes or no" question. Can you please clarify whether you meant "yes, it applies before cap" or "yes, it applies after cap"?

I also have a follow-up question about getting Aether Premeation as a non-archmage. Will it become clear how to get exposed to the void of space by just winning the game? Or is there a trick in an optional area?

The trick is entering a random event area or selectable path to the end of the game.

Aether Permeation checks your res cap, so if you have 100% arcane resistance, but your arcane resistance cap is 75%, then your other resistance will be set to 50%

Thank you both for the answers.
