ROTATION
(Start with all 6 Illusions Out) > Perm Spikes > Enthrall > Binding > Ruin > Sig > (Resummon Illusions) > Spatial Deception (filler)
IN DEPTH:
-I use Arcane Ruin's cooldown to time my rotation. Let's call Perm Spikes+Enthrall+Binding "combo". Always resummon after Ruin.
-Start with Illusions > combo > Ruin > *SD > combo @ 5s CD > SD > Ruin > combo > SD > combo @ 1s CD > Ruin > restart from *.
-Hit sig on cooldown.
NOTES:
-His teleport and Spatial Deception each have a couple seconds of internal cooldown before they can summon another illusion. Illusionary Projection does not have this issue. As such, after Ruin, I will Projection x4, teleport (5th), then Spatial Deception (6th). You can Projection x5 then Spatial Deception for the 6th, but if you TP directly after the 4th Projection, it's quicker to get the Illusion out.
-Spatial Deception does not summon illusions against Surtur. Use Illusionary projection x6, or x5 and 1 teleport. It's annoying, but only a slight DPS loss.
-In a party/raid/patrol zone, you can usually remove Perm Spikes from the rotation. Someone else is definitely providing vuln for you, and someone else also likely has the "Power" aura. If you see no timer note on the "Power" aura icon in your buff page, it is safe to stop using Perm Spikes. If another hero provides a chill effect (such as Iceman), you can also stop using Perm Spikes, as it won't be needed to activate the "Power" aura. Dropping Perm Spikes from the rotation is actually a pretty decent DPS gain.
EXTRA INFO
Alternate Gear:
Slot 1: Laevateinn, Soulsword
Artifacts: Moleman Staff, A.R.M.O.R. Alternate Reality Chaos Portal

Shield of Perseus and Lemuria Relics are good options if you feel squishy.
There are spots at Onslaught where some of your attacks don't hit. Most notably, directly in front of him. However, if you move a few paces left or right, all your attacks will hit again. You can tell if you are in a dead spot if your Arcane Binding chains animation is no longer applying to Onslaught. If your chains animation is applying, and you are within melee range (which actually goes quite far back on each platform), all your attacks will hit, including Spatial Deception.
