Turn 2Teleports: The Avatar fades into existence right between Retinue 2 and a lot of broken eldars
Init Eldar
The Fire prisms decides to put some hurt on Retinue 1 and advances, 3 rhinos are destroyed in the process before they take a slight step back and settles down on the eldar blitz.
Now the aspect warriors engage, in the fight containing two pissed of Death Guard formation and one really frightening aspect formation, 5 death guard units walks away to say hi to Nurgle, but in the exchange all but 2 units from the aspect formation is destroyed by some wicked rolls on my part. The aspect warriors, now consisting of one Autharch and one wave serpent retreats behind the broken Guardians and Rangers. Retinue 1 gets broken by all the losses and retreats behind Retinue 2
As a reply to this, the Avatar makes a furious charge right into the victorious marines from retinue 2, slaying 2 units in the formation to no loss himself, but looses the resolution roll and have to disengage.

Retinue 2 takes this opportunity to marshal and removes all blast markers.
The eldar jet bikes takes this opportunity to make themselves known and engages out of the wrath gate, engaging Retinue 2, and as the marines tries to get hold of those pesky bikes that refuses to fight like men, they loose 1 rhino and 1 marine unit to the loss of only one viper bike, and the retinue retreats with a few working rhinos and a few angry, but broken plague marines. The bikes approach the decimator while the marines take cover behind a few pieces of broken spaceship.

Again the eldar retains and from the gate formations of warp spiders emerge. They engage the armoured company and wipe them all out without loosing a single unit themselves.

The heavy retinue marches over to take position around the wrath gate again, where so many of their fellow marines have ended.
The decimator advances slowly and gets some broken aspect warriors in his sight, one giant explosion later, not a single model remains and a guardian and ranger units disappears as well in the explosion.
And as the last formation left unactivated the Contagion Towers takes careful aim and sustains into the tightly packed warp spiders, and 5 of them succumbs to the Nurgle goo and the formation breaks, retreating back to their own lines.
End phaseAll Death Guard formation, but eh heavy retinue rallies
All Eldar but the Guardians rally
