Thordan Tip:

During the two Knights phase with shield oath and sword oath, three players (DPS if everyone is alive) will be marked with a blue marker. This means they will he jumped on, and damage dealt to the raid increases the closer they are to marked target.

In my experience the ranged DPS get marked first. Both ranged should wait for medica 2 or some sort of regen/shield then get into place before the marks even go off. If the knight with sword oath is to the east, then the ranged must take southwest and northwest. If the knight with sword oath is west, then the ranged take southeast and northeast. After the damage goes out they must run to the middle for heals.

By doing this, the melee targeted just have to run southeast/northeast if the sword oath knight is east or southwest/northwest if the sword oath knight is west (and therefore won't lose much DPS and still retain enough distance to not harm everyone), and the last person to be marked will be on the opposite side.

This keeps damage low and allows healers to top everyone off for holiest of holy. Use virus, dragon kick, whatever to mitigate this ability, and don't use blood for blood until after holiest of holy. This will make this phase smooth sailing and you can proceed to get rekt in the next phase instead :)
