FFXIV Endwalker Guide: The Mothercrystal

The Mothercrystal is a Final Fantasy XIV: Endwalker Main Scenario Quest trial. It’s available at level 89 as part of the quest Her Children, One and All. It can be completed via the duty finder.

For the sake of your fellow players, please remember that this is new content (at the time of this publication). A little friendly explanation can go a long way. Similarly, don’t be afraid to take advice. You may learn something you didn’t know.


Phase 1

  • Hero’s Radiance – Arena-wide damage.
  • Dawn Mantle – The boss will put out 1 of 3 different indicators in a set that swirls around them:
    • Red chakrams: A donut AoE. Move into her hitbox. (This first one is always red.)
    • Green staff and shields: A point blank AoE circle under her. Move out.
    • Blue sword and shields: A cross-shaped AoE. Move to intercardinal directions relative to the way she is facing. If you get a little lost during all the moving, use the line to mark the flank on her hitbox as a guide.
  • Mousa’s Scorn – A tank buster that must be shared by both tanks.
  • Dawn Mantle – This second one is always green.
  • Mago’s Radiance – Arena-wide damage.
  • Dawn Mantle – This third one is always blue. All Dawn Mantle casts after this are random.
  • Hero’s Sundering – A tank buster. This is taken by a single tank this time, but the swipe is large, so be mindful.
  • Dawn Mantle
  • Mousa’s Scorn OR Mago’s Radiance
  • Dawn Mantle

Phase 2

The goal here is to destroy all 6 of the Crystals of Light while dodging a smattering of AoEs cast by Echoes of Hydaelyn:

  • Hydaelyn’s Ray – A linear, proximity based AoE. Move to the edges.
  • Crystalline Stone III – A stack mechanic.
  • Hydaelyn’s Ray
  • Crystalline Blizzard III – All players will be marked with a traveling, circular AoE. Spread out.

Once all crystals have been shattered, Hydaelyn will treat you to her signature move. Mitigate and heal as needed.

Phase 3

  • Crystalize – Hydaelyn will choose an element here, each one indicating a future mechanic to be done after the next Dawn Mantle:
    • Ice: Spread out to avoid stacking AoE circles that all players will have.
    • Earth: Stack together to soak damage.
  • Dawn Mantle
  • (Now do the Crystalize mechanic!)
  • Mousa’s Scorn
  • Parhelion – The boss will launch 3 sets of 5 chakrams each equidistantly out toward the edges of the platform. Avoid the initial strikes and go stand next to the first set to fan out.
  • Subparhelion – She will recall the chakrams, launching them back through the center of the arena in a sort of hour glass shape. Step from that place you preemptively moved to after Parhelion into the safe space left behind by the first set of chakrams relaunching away. (This is only one of several perfectly acceptable ways to dodge this.)
  • Crystalize
  • Dawn Mantle
  • Parhelic Circle – A starburst of yellow lines will appear on the floor. At the end of each line, a ball of light will appear, eventually exploding in a circular AoE, so space yourself away from the ends of the yellow lines.
  • Mago’s Radiance
  • Crystalize
  • Dawn Mantle
  • Hero’s Sundering
  • Radiant Halo – Arena-wide damage.
  • Lightwave* – Four waves of light will appear beyond the rim of the arena. Project their lines of travel to find the safest area to stand in. I tend to find the 2 waves that are nearest to one another visually and go to the opposite side of the arena from them. If they’re close at one side, that means they’ll be far when they cross. Adjust for the other 2 waves as needed.
  • Echoes – A stack mechanic with 5 hits. Stay together for all 5. You have enough time to deal with this mechanic in the center of the arena before the light waves start moving, but moving preemptively is perfectly acceptable a well.
  • Crystalize
  • Dawn Mantle
  • *Repeats from Lightwave until defeat.

Congratulations, you’ve completed The Mothercrystal! (That’s a much sweeter phrase!)
