Just finished this part, and I have to say: it literally took me, I swear, at the very least 40 reloads, possibly closer to 50, since I either missed the getting everybody properly aligned, on all 4 supports when I used the aard (and you have to hit every one to knock the little critters back or else they'll swarm you -- though sometimes they do anyhow and then it's Game Over.... again), or else once I've collapsed the support: I found a bunch of little kikimores blocking my path and thus was unable to proceed -- even by dodging -- and could only fight them until the Queen came along and killed me.It's situations like this, in CRPG's, that make me think how nearly impossible the protagonist's situation is. In this case: I can only conclude that for Geralt -- not the player -- it's next to impossible for him to get through this. He'd have to be extraordinarily lucky. Which bothers me because, in my eyes, this means a flaw in the writing.As for strategy, based on what I've discovered in my 40-50 attempts:1: You cannot kill the Queen. Don't even try. With one swipe of her leg she'll kill you.2: When you use the aard on the first support: the Queen has to be positioned precisely in the emergent position -- in other words, underneath the supports and just emerging from them. The aard will push her back -- hopefully as well as the small kikimores nagging you from behind, thus clearing the way for you to proceed -- and collapse the supports. You have to be far enough away so you don't get crushed, but not so far as to not be able to hit it. In other words: near the back wall and just slightly to the side. Once you've cast the aard: don't wait to see the results. IMMEDIATELY turn and RUN.NOTE: Despite any suggestion to the contrary: if you zap the supports before the Queen gets there, the supports will not wait for the Queen to arrive. It doesn't work. The aard will fail to topple the supports, and the Queen will come through and kill you. She needs to be right under the supports and just coming out from them.NOTE: This will be the only point where you'll have the luxury of waiting. Remember: every time you zap the supports: RUN.Also: the first supports are the only ones where you'll have to wait until she's emerging. On the others: hit the supports when she's under them or just getting under them. A little later and it'll be too late.3: On your way, DO NOT ATTACK ANY KIKIMORES. Unless somehow the Queen gets stuck -- a rarity -- she'll come after you at lightning speed and kill you. You have to get past the next support as fast as you can, turn, you'll see her approaching, when she's just under the support, zap the support and move on.4. Next supports are just at the entrance of the large gallery with all the support poles. Make sure you don't miss it. Turn and hit these, then move on.4. You'll have to position yourself just beyond the middle of the final three poles, about as far away as you were from the first. Too close and you'll be covered in rubble. Too far and the aard won't work. Essentially: O O O X...If I remember correctly (I didn't get to this point often) I think there's a crack there and you should stay just beyond it, no further.FINAL NOTE: Once you cast the aard on the final support: RUN RUN RUN! Or you'll be crushed.
