Supermassive (25 player)

Black Holes are formed when Collapsing Stars die, unleashing an explosion (10/25). They have a void zone type effect and are used to port out to escape the Big Bang (10/25).

This achievement seems to refer to the closing of Black Holes by kiting the Living Constellations into them - the kiting seems to be easily done by a mobile healer (e.g. tree druid).

JUST A WARNING:

You must NOT be inside a Black Hole when Algalon is killed/does his speech or you WILL NOT get credit for this achievement nor this

Learned this the past lockout, a friend submitted a ticket and the GM response was "Too bad, do it again."

To clear up a few issues that people tend to gloss over.

1. "Kill collapsing stars as close as possible to each other" - these stars spawn randomly pretty spread out, and slowly wander around. If you get two let alone three fairly close to each other that is pretty lucky. More likely you'll get two kinda close to each other and the others pretty far out. There is simply not much you can do about it as you only have the time until you get four stacks to hope they get closer.

2. "Kite living constellations over the black holes" - again, this sounds so simple, but it's not. The constellations spawn from the ceiling and head towards you, but it's not good enough for them to simply pass over the black holes. They have to be basically at ground level, otherwise they simply float over the black holes doing nothing. Really really annoying as you have so little time to kite.

3. The living constellations spawn at four stacks, and the fight resets at five stacks. Do the math, that means you have the time between four and five stacks to figure out where the constellations are coming from, get to the other side of black holes, hope they collide with the black hole instead of floating over, then run around to another black hole and repeat. If you do get it, it will be a split second before the fight resets.

4. Kill Algalon the Observer on the toon before attempting this achievement. Many reports of people that it's bugging out if you are trying to do this achieve on your first kill. If you've already killed him, then you will get the toast popup the instance you have three collapses. It's not obvious at all with all the visual stuff going on.

5. It is nearly impossible to do this with most classes, but with a Hunter or Brewmaster you can pretty much ignore the phase mechanics and get it in a couple of tries. Either use a pet on passive or an ox statue to sit on the boss AND the constellations. Yes, if you are reasonably lucky with the constellation spawns you can get them to stick to your pet/statue. Then you wait for several groups of black holes to form. This is not really possible if you are directly fighting Algalon, but because the pet/statue doesn't get phased by stacks the collapsing stars just keep on coming making it less difficult to get several overlapping. When you do get a reasonably compact group of three or four black holes, you sit on the far side from your pet/statue holding the three constellations. At this point, you release your pet/statue and the constellations beeline right at you and hit the black holes. The main difficulties are to not accidentally step on a black hole, and to not accidentally cleave/multishot Algalon.

What I'm trying to say is not to get down because people make it sound like this is so simple. For the majority of classes it really isn't and it comes down to some pretty good luck with rng.
