ToME: the Tales of Maj'Eyal

Pretty much what the title says.

I figured a proper way to clear house with Linalil and did it, but I did not get the achievement 'Now this is impressive' from it. I was playing on normal+adventure mode. I think it might be because I revived with the Blood of Life and was on my final life.

The achievement was added in 1.05, not 1.04.

You are not currently able to achieve it, unless you are playing the beta.
