ToME: the Tales of Maj'Eyal

I've just found Forbidden Tome: "The Day It Come", but I'm unable to pass the third test.
I've been trying all three talents in multiple combinations, but still can't find how to pass my "death" on dummy.
Please help.

You need to get your health very low through entropic backlash, use Fatebreaker on the dummy, and then "kill" yourself with a Netherblast before it expires.

Thanks for your response Velorien, but it doesn't seem to work :/
I did the following:
1st turn
HP: 1/100
No active effects
Netherblast and Fatebreaker ready to be used
So I cast Fatebreaker on dummy.
2nd turn
HP: 1/100
Fatebreaker active
I cast Netherblast on same dummy.
And get an effect of losing 0 health to entropy.

When I tried using Fatebreaker in combination with healing infusion I got to a point where I got following message:
Hithre loses 14 health and is almost overcome by the entropy!

Is it a bug or am I definitely in a correct forum...

I cast Netherblast on same dummy.

That's the problem, you should cast it on yourself.

Entropy cannot kill you directly - see the last line of the first paragraph of Entropic Gift's description. You gotta blast yourself.

There was a text box in game that described the process - if you fail out of the book you can just go back in again and read it, I don't *think* there are any consequences to repeating it.

(Also, I'd like more training montages like this in the game. "If you can block a wrench with your face, you can Stone Warden!")

Got it!
Thanks, I'd try it now, but I got overconfident and got killed in the meantime
Seemed to me that playing writhing one on nightmare was easy as playing an oozemance, but just got killed inside different book despite having level 50...
