So I understand that in 2.2, Philosophy tomes will be removed from the game, like the interview says:
Tomes

No more Philosophy after 2.2
Myth will take Philosophy's place
There will be an NPC around to trade Phil for Myth.
What I don't understand is how the Philosophy Items and the Radz-at-Han Quenching Oil will be handled without Philosophy. My assumption is that Radz-at-Han Quenching Oil and items will be either moved up to Myth or dropped like DL will be from dungeons. Can anyone guess what will happen?

Also, Thavnairian Mist, will that get moved up as well?
