My first 8th edition game, a month ago, was a cruddy army that underestimated Daemons and got slaughtered. For my second game, after increasing my unit sizes, I hoped to do better.

My army:
Runelord, Anvil, sh, Stone, MroBalance, spellbreaker
BSB, gw, MroGromril, Resistance, Preservation, Furnace

39 warriors, gw, fc
39 warriors, gw, fc
26 Longbeards, gw, fc, MRoGrungi

Stone Thrower, Engineer, pistols, Accuracy, Penetrating, Penetrating
Stone Thrower, Engineer, pistols, Accuracy, Penetrating, Burning
bolt thrower, Engineer, Burning
bolt thrower, Engineer
Organ Gun
Organ Gun

Super simple. 3 blocks, artillery behind. The bolt throwers sit alone way out on the flanks - if the enemy wants them dead, he can kill them.

Daemon army:
Keeper of Secrets, Torment Blade, Siren Song
Khorne Herald on juggernaut with armour
Khorne Herald on juggernaut with armour
Tzeentch Herald, BSB, Lore of Life, spellbreaker

14 Horrors, fc
₃₀ Bloodletters, fc
5 Furies
5 Furies
12 Flesh Hounds
8 Fiends

I deploy predictably - Anvil, stone throwers and Organ Guns as close together as possible on the table edge. Combat blocks as close in front of them as possible. Longbeards 5 wide in the middle with BSB, Warriors 10 wide on either side.

I won the roll for first turn. He ward saved one stone thrower, and the other misfired losing next turn on both rolls. But one bolt thrower put 3 wounds on the Keeper, and the other killed 2 entire Flesh Hounds. Wow! Then I anviled the Keeper to slow him down.

He came forward, I stopped his magic easily.

On my second turn, he wanted to Siren a warrior horde into the Keeper, but had landed a Fury unit too far forward, so the charge was impossible. Siren Song is really what makes the Keeper incredible in 8th edition - he can get into combat faster than a Bloodthirster, which means he gets shot less. But since Jeff messed up with the Furies, I got another chance, and the healthy Stone Thrower finished him. Bolt thrower killed another Flesh Hound, while the two Organ Guns dropped about 3 Fiends. Most importantly, the Furies that blocked the Siren charge were close enough for a reliable Anvil charge ... with an Overrun into his BSB and Horror block. Warriors horde moves to 6 inches away, anvil works, warriors charge. Furies take out 2 warriors before dying, but I pop them and get the overrun. Except I overrun just 3 inches, leaving me short of the Horrors and giving his BSB a chance to escape.

He then throws his Fiends into my other warrior block. I had foolishly reformed that block to 5 wide, because I thought the Flesh Hounds (which contain the 2 Khorne Heralds) would be ramming into them, and extra attacks are useless against that pair of juggernauts. The Heralds abandon the Flesh Hounds to join the Bloodletters, who swift reform to 7 wide (originally 10) and advance towards my Longbeards. Furies charge Organ Gun, and will eventually kill it. Fiends and Warriors kill several on each side.

Warriors charge Horror block, to finish it off and then try to chase his BSB. Shooting for the Heralds, who don't get "look out sir", both Stone Throwers misfire. The Organ Guns produce a pair of 10s on the Flesh Hounds, but roll terribly to wound and only kill a few. The Anvil tries to save the Longbeards from certain doom by slowing the Bloodletter block (with the heralds), but misfires. Fiends are reduced to one injured model.

Flesh Hounds flank Warriors that are fighting the Fiend, but I think I can beat that off. I win combat on the musician, leaving 2 Flesh Hounds alive. Bloodletter block charges Longbeards with BSB, and butchers them. I lose 10 guys, 7 or 8 from the heralds, and kill an irrelevant number. Longbeards with BSB are broken and run down, but both of us roll net 3 for flee/pursuit, so he doesn't reach the Anvil yet. Their loss panics an Organ Gun off the table.

With the Anvil not engaged, the victorious warrior block is able to swift reform and anvil charge into his BSB, killing him. My other warriors finish off the Flesh Hounds, and commence marching away from the double Heralds of doom. Those Heralds take out the Anvil and one Stone Thrower, while the Furies eventually finish off the Organ Gun, one Stone Thrower, and one bolt thrower on turn 6.
The warrior block that killed the Tzeentch stuff is long gone on the other side of the table, but the other block has to flee two charges from the block with Heralds of Doom. They flee far enough to live, and the wacky 8th edition rules means their ending the game fleeing is no penalty!

I have 890 points on the table, from the two warrior blocks and one bolt thrower. He has 870 from the Bloodletters, 2 Heralds, and one Fury unit. We each captured 2 banners. 20 point draw.

Going first is the only thing that gave me a chance. If he goes first, I definitely don't kill the Keeper, and while I might have gotten one Herald, I would not have gotten both. Daemon infantry, while being the worst stuff in their book in 7th, was/is still better than almost all other infantry in the game.

Against a Keeper of Secrets, the proper deployment is everyone facing backwards. That way he cannot Siren Song you turn 1.
