Haha, no, I understand what you're saying; I know how Vorpal works. But its effects only activate on a roll of 20; the other two things are passive and work regardless of what you roll (unless you miss, of course). I'm just not a fan of (relying on..) RNG effects, really. I'm more in to passive effects that I can easily see a difference in, rather than "oh, that just happened. okay, next mob". Don't get me wrong, a passive Vorpal effect is nothing to laugh at considering the wraps I'd be using (Antipode, or something crafted perhaps), I just don't like the RNG involved is all.
However, I will admit that the Phantasmal Killer effect of the Traraak Wraps happens frequently. I believe I've actually noticed it activating from offhand and/or Doublestrikes, and I've had it, somehow, kill two targets at once, which is neat. And it can be negated by a save.. Vorpal cannot.
But with the advent of considering dropping CON to about 10 in my next life, I could get both Overwhelming Critical and Vorpal Strikes. If I had to pick between the two, though, I'd choose Overwhelming Critical and make the build work around it.
But now I'm curious.. as to how the person above is achieving a bit over 900 HP at L28, with GMoF active, with only 9 CON. My L16 Monk has 21 CON currently and wouldn't have anywhere near that with GMoF active, unless there's something I'm missing. I won't be able to stack Yugo pots either, considering my Monk never got to run ToD before I took a long break from the game. So assuming a Health +10 item (19), Earth Stance (23), ship buffs (25), probably exceptional bonuses in there somewhere (<=28).. I'm curious of how such a high number is happening. Unless Yugo pot stacking is exactly how it's happening.. which, if that's the case, makes me a little sad.. to have to rely on those pots to achieve certain thresholds. (This isn't taking in to account things like GFL, Vitality, etc.)
