Their strategy involved having 3 groups (setup in the raid finder), which rotate absorbing the Hour of Twilight (2->3->1 I believe) and a 4th/5th group which never take the brunt of Hour of Twilight. There is a 2 minute interval in between when groups can take another Hour of Twilight, 45s cast interval, and each hit deals 300k damage which must be mitigated in some form.
Example Groups:
Group 1:
Durka - Cauterize
Expo - Cauterize
1 Holy pally w/ a bubble rotation
Chimi - Disp
Typh - Cloak + Feint
Group 2:
Schwebels - Deterr
Halicon - Deterr
Zoras - Deterr
Berry - Survival Instincts
Mag (assuming he tanks) - AMS
Group 3:
Pael - AMS + IBF
Plagued - AMS + IBF
Hyron - Stance Dance Shield Wall
Witt + Guardian Spirit
Esp (assuming he tanks) - GoAK or AD or Glyphed DP
There should be 7 casts total, so group 1 would absorb it 3x, group 2 2x, group 3 2x. After that, it'd be a wipe
Tanks have to taunt BEFORE the other tank goes into Twilight for Fading Light, as physical damage taken is INCREASED by 100%.
