First and the Last

 Had a Warmachine Mk4 game.

My list:

Scaverous
- 2x Corruptor
Bane Warriors + attachment
Bane Lord Tartarus
Pistol Wraith
2x Necrotech

Opponent had:

Bane Witch Agathia
- Desecrator
- Reaper
- Deathripper
2x Bane Warriors
Bane Riders

Scenario was one from Steamroller document.

Scaverous started game and rushed forward. Agathia used her feat right at the start and gave stealth to almost her entire army, so on my second turn there was little to do. My warjacks lined up behind long wall in the middle, while Bane Warriors went to flank from the right. Pistol Wraith was sitting in the forest with Skarlock behind the secret gathering of trees. 

I did, however, manage to take a shot at Bane Rider in cover with Corruptor, and kill a single Bane Warrior with burster attack. 

Agathia repositions with all of her army to the circular zone, leaving a massive advantage for me in scenario.

Bane Riders went to punish Pistol Wraith, getting in range thanks to vengeance. Magical weapons came from a command card. 

Desecrator managed to snipe one of the Necrotechs dead with boosted blast damage roll. 

One unit of Bane Warriors ran to make a wall between Corruptor and Reaper, which had run to the zone as well.

On my next turn one of my Corruptors uses the unstoppable command card and charges Bane Riders. That activation was... less than ideal. I thought Corruptor would smack the rider dead and spend remainder of its focus bursting some Bane Warriors too, but all it managed to do was three points of damage to Bane Rider. 

Scaverous uses feat and casts Feast of Worms over Reaper. Second Corruptor removes some Bane Warriors with a ranged attack, which was far more effective than melee. I mean... it killed two models!

At least Bane Lord Tartarus did anything useful that turn - he single handedly, dual attackedly, wrecked Reaper. Skarlock also finishes with Excarnate what a Corruptor couldn't in melee with three focus... Removed that Bane Rider.

 My Bane Warriors ran to engage Desecrator.

Agathia removed Bane Lord Tartarus and a Corruptor and Bane Warrior Officer, but did nothing to contest scenario. 

After my turn I would have been at four victory points. So I don't know why I opted to killing Desecrator... But so I did. Scaverous moved into position to make a nice thresher attack, cast Feast of Worms and then failed to hit Desecrator. Yeah, not good. 

So I go into a kind of panic mode and want to make sure the warjack is gone from next to my warcaster. 

Bane Warriors run to give some Dark Shroud for Desecrator, and surely enough Corruptor kills last heavy jack from Agathia. But now that my Banes were not engaging enemy Banes, Scaverous had to sweat through five charging Bane Warriors - a terrifying prospect when Agathia hits Parasite on my caster. 

Scaverous has a focus point to blocking damage, but still takes eight damage in from the very first attack. Three Bane Warriors proceed to miss so I start to get a little hopeful - but nope, not today. Last Bane Warrior hits Scaverous and 4d6-1 didn't come out 7 or less. 

Maybe this was a lesson for me. I just needed one point.
