Damn 1000char limit... So letting everyone hover at a bit of missing hp till the Twister cast is done might give you that extra half second to clear the landmine. After Twister though, the healers would have to be ready to top off the tank to survive the Death Sentence that follows, but that shouldn't be too tough.

Just an idea, I doubt it's something this simple. Also would like to point out that in the video of them actually avoiding 3/4 of the Twisters, 2 of the survivors were not fully topped off at the start of the cast/after it was finished. The third survivor (Teloc Arioch) is however topped at the end of the cast and it would appear he was likely full at the start of the cast... what this means is that this theory is likely flawed or inconsistent. Meh, even though I'm skeptical about this being the case, figured I'd throw it out on a 'strategies' thread. Here's my throat.
