The other comments make this way more complicated than it needs to be. Do it on normal, just start the fight, afk till two sets of tentacles are up or at most kill only one or two of the first set. When the second set spawns, lust and nuke them all down.

Each time you kill one of the Tentacles, the boss will gain 20 Agony. That means you will need 5 dead to start his Thrones of Agony.

There are 2 that start with the boss, Kill them and 4 more will spawn. Mark one to NOT kill (but get it very low on HP). Kill the other 3.

When he starts casting his thrones of Agony, quickly kill the one that was designated to stay alive and 4 more will spawn.
HERO/Bloodlust to kill the remaining tentacles down in the remaining time (60 seconds).

Added note, make sure you are getting your seed (orange/yellow ring) to them to get added damage.
