Graven Image

When Graven Image is cast for the first time on one of the three statues, a big mechanic, different from normal mode, needs to be handled. Every other time, the mechanic is the same as normal mode.

Below, each big mechanic is described. The first two statues are described mostly by pictures, the third and last in text.

First Statue

The DPS spread horizontally, from west to east: R3, D1, D2, D4. Tanks and Healers bait and avoid AoEs near the middle.

Try not to spawn AoEs such that they block the path north. Tethered players may need to go north.

DPS need to take care not to have their beam hit anyone else but themselves. Only 2 beams go of at a time, the animation shows all 4 going off for illustration purposes.

Assigned positions:

A Tali + D1
B Ahmed + D2
C H1 + R3
D H2 + R4

Second Statue

The animation shows stone hitting all players. In reality, only dps, or tanks+healers will be hit. This means, that for the second time Stone hits, people without tethers can start moving to Kefka a little bit, as long as they do not come near the others that do get Stone. This is optional, so no need to take risks.

The danger side is not always right. The danger side is telegraphed by a large glowing orb on the statue north. The same as in normal mode Kefka.

Positions from North to South (using the same buddy pairs as before):

1 H1 + R3
AB Tali + D1
CD Ahmed + D2
2 H2 + R4

TL;DR

Stack, Spread, Safe Half.

Stack, Spread, Aero.

Third Statue

During this Graven Image, normal mode style Eye mechanics will happen multiple times. The animation on the right is an example of how the mechanic might turn out. Three things are random, the first eye mechanic (look away or look towards), who gets which tethers (Left: Confuse or Right: Sleep) and the second eye mechanic (look away or look towards). These are all three independent of each other.

Walkthrough:

Boss should be positioned as he was on the pull (butt on the center, facing north).
AoEs should be baited in the center of the arena.
Dodge north if eye is orange, dodge south if eye is purple.
Everyone moves slightly to assigned positions.
Once tethers show up, those tethered to the right statue (DPS or Tanks+Healers) go to the center (sprint may be used or saved for the teleport later).
Left tethers go to assigned positions and spam the macro, or click off Sprint (though Sprint should not be used at all).
After confusion and sleep wears off, handle the eye mechanic again and get behind the boss before teleport finishes, like during the first Graven Image (use sprint if you still have it).

The DPS will be tethered to the left or right tower. The rest will be tethered to the other tower. All players tethered to the right statue must stand in the dead center of the room and will be sleeped. Players tethered to the left statues should place themselves on assigned positions at the edge of the arena, before becoming confused:

A Tali / D1
B Ahmed / D2
C H1 / R3
D H2 / R4

Click off sprint before confuse takes effect or do not use it at all. This can be easily done by spamming the macro before and/or during confusion.
