[Solved] Stuck in Surgical Strike (spoilers)

[Joramun]

Hehe, I finally found the three topaz keys,
which enabled me to have the four master keys.

Now, I'm in Venom, and though I have tried a lot
of different potions, I'm not sure I grasp the full
meaning of "Open Your Mind, Open Your Way".

Maybe it's not about drinking something, but then
I'm quite confused about what I should do.
( I also ate some herbs, but there's no way to smoke it )
(I even tried the see-through walls spell..)

[Trantor]

I remember being stuck at exactly that point. You actually have the correct idea with the herbs, but as you said, you can't smoke them. Maybe someone already did that for you and left just the smoke?

[Joramun]

For some reason i always forget that such an item can have attack
methods... Nice effects anyway.

I'll have to figure out the ven spawning chambers, now

[Joramun]

Finished !

(not without hints) 56km and 6h of game time.

I got only two endings, though. (with and without hellion)

[Trantor]

Congratulations! And yes, putting the needed item in my action hand was about the one thing I didn't try out. *sigh*

I should try that dungeon again. I think I found all endings, but certainly not all secrets... Something like 9/17 or so...

I never got to see the DDR section!

[Joramun]

I got 12/17, but I did not push the search very far,
and I didn't bother completing the secrets games.

(finding the 3rd topaz key was already a big job).
