Are You My Broodmother?

Nascent Ruby Egg is in the first room nearby the dungeon entrance, behind the pillar, hide in grass.
Only one egg, everyone can pickup it, but suggest tank carry egg because achievement need you soak damage.
You will get debuff when you pickup it without negative effect, mount or dead will drop the egg, and it will disappear after 5 sec if nobody pickup it again.

Soak [spell=384022], become [npc=198596] with gray fog on the egg;
Soak [spell=372863], become [npc=198599] with red fog on the egg;
Soak [spell=381525], become [npc=198598] and drop to the floor, can be target, keep losing health and healer should keep it alive until defeat Kyrakka and Erkhart Stormvein.

The achievement requires you to be hit by abilities from all three bosses in the dungeon, so if you haven't picked up the egg it will despawn after killing the first boss. This is one of those achievements that's worth doing it's own run for apart from the other 2 in case you wipe (especially on boss 2's achievement, as this is being posted on week one of DF).

My group had alot of problems with this achievement...
We did the whole dungeon multiple times where the egg would just disappear randomly, even when we had it on focus.
Some addons can cause issues where you cant see the eggs nameplates, so my tip is to use a focus mouseover-macro.
Mouseover the egg and use the macro to set it as focus. Atleast have your healer do this.
/clearfocus
/focus [@mouseover,nodead,exists}

As i said we had alot of issues where the egg would just disappear randomly. You can minimize this risk by doing small pulls and going at a slow and steady pace. Dont pull the entire dungeon.

First and second boss is very easy, but last one can be tricky:

• Just stand in the white swirlies ([spell=384022]) on [npc=188252] to have the egg chilled.
• 
  
• Soak the big swirley that spawns the add [spell=372863] on [npc=189232].
• 
  
• On last boss we killed [npc=190485] ASAP to minimize the risk of having the tank one shot by [spell=381512]. After that we brought [npc=199790] to 10% HP and waited for [spell=381525] to hit the tank and then we killed the boss. This way you dont need to heal the egg at all.
  
  Good luck with the achievement and remember to clear the trash slowly!
