[Shadow Stranger]

I have not checked that the Valkyrie actually attains the normal hit points, spells and skills when she gains levels. I believe she should, unless that is stored in the town record that I altered.
Edit:
I have just checked whether the Valkyrie seems to gain the usual spells and skills, as far as I could tell, she got all her usual spells and skills. Once the Valkyrie ascension is complete you may need to cancel the original Warlock training, the latter may still be running. Cancellation is quick and simple.
Only the Brimloch Roon Temple Warlock ascension is affected. If you are a member of the Priest Guild you can still do the Warlock ascension at the other two towns.

Monk ascension could be fixed too, about time. Maybe hack the Paladin ascension quest in one of the temples... Ishad N'ha comes to mind. You could hack the ascension there. As it is a hack of the Paladin ascension, you become a Monk immediately when you report back after praying at the Altar.

On second thoughts, the Monk ascension code is a bit different:
4, Ranger, 35, 255, 255, 1, 0, 0, 2, 0, 40, 4, 0, 0, 1, 0, 41, 0, 4, 0, 42
5, Bard, 35, 255, 255, 2, 0, 0, 2, 0, 40, 5, 0, 0, 1, 0, 41, 0, 5, 0, 42
6, Samurai, 35, 255, 255, 4, 0, 0, 2, 0, 40, 6, 0, 0, 1, 0, 41, 0, 6, 0, 42
7, Paladin, 35, 255, 255, 6, 0, 0, 2, 0, 40, 7, 0, 0, 1, 0, 41, 0, 7, 0, 42
8, Barbarian, 35, 255, 255, 8, 0, 0, 2, 0, 40, 8, 0, 0, 1, 0, 41, 0, 8, 0, 45, 0, 0, 42
9, Monk, 35, 255, 255, 9, 0, 0, 2, 0, 40, 9, 0, 0, 1, 0, 44, 0, 0, 41, 0, 9, 0, 42
9, Monk, 35, 255, 255, 9, 0, 0, 2, 0, 40, 9, 0, 0, 1, 0, 41, 0, 9, 0, 42
10, Ninja, 35, 255, 255, 11, 0, 0, 2, 0, 40, 10, 0, 0, 1, 0, 41, 0, 10, 0, 42
11, Warlock, 35, 255, 255, 13, 0, 0, 2, 0, 40, 11, 0, 0, 1, 0, 41, 0, 11, 0, 42
12, Assassin, 13, 236, 0, 40, 12, 0, 0, 1, 0, 41, 0, 12, 0, 42
13, Zenmaster, 35, 255, 255, 18, 0, 0, 1, 0, 40, 13, 0, 0, 1, 0, 41, 0, 13, 0, 42
14, Valkyrie, 35, 255, 255, 21, 0, 0, 2, 0, 40, 14, 0, 0, 1, 0, 41, 0, 14, 0, 42

I don't know if the extra 44,0,0 is needed or not. What I can do is make the "No" choice in "Do you want to cancel your Monk training? Yes/No" link to the start of the Monk ascension code. This also means that I don't have to hack the Paladin ascension.

Edit:
"13, 236, 0," means: remove item 236, the Assassin's Dagger. So the real function to enact the Role Ascension would be "40, 12, 0, 0, 1, 0, 41, 0, 12, 0, 42"?
The " 35, 255, 255," may be related to setting a quest as completed.
