Ven - which way you goin'? 

Venovar decides to follow Thorvin, and once he gets to the ogre, he takes a jab with his halberd at the grotesque monster and then moves back behind Thorvin. Attack: 21 Damage: 5 the weapon digs deep into the zombie. (-7)

Next Round: (Zombie Ogre > Gotur > Alton > Thorvin > Venovar)

The zombie, clearly angry from just getting stabbed, tries to get at Thorvin but is quite a sight when this thing tries to sardine its way through the 5ft passage. It sees that Thorvin is in front of the exit, and tries to swing wildly at the dwarf. This is done at disadvantage because the ogre is stuck in the passage. Like a cork in a wine bottle. Attack: 14 Damage: 8 the huge morningstar slams into the wall and the ogre looks akward trying to swing it in that small space.

Gotur, Alton, Thorvin and Venovar are up! If you attack the ogre zombie, it is with advantage. 

(let's take stock of who wants to continue to play etc. after the party deals with this last section.)

 Gotur, somewhat expecting to have flanked the ogre in the narrow hallway, but seeing that it seems stuck, and the others are attacking from the far side, moves south, does a thorn whip at it, then moves south to give Alton a shot.

Attack: 15 Damage: 4

 Venovar will take a stab with his halberd, because he cannot really do anything else.

Attack: 12 Damage: 9

Gotur and Venovar, both of your strikes hit the zombie ogre. The thorn whip thrashes its back, and the halberd once again plunges deep into the ogre's grotesque fat.

(-12 total damage for those attacks)

Alton is up! I will make Thorvin's move after Alton goes.

(Map is the same except Gotur has moved south)

Alton uses 15 feet of his movement to run down into dagger throwing range of the Ogre, before throwing a dagger (Not sure if sneak attack is applicable, so will roll it separately). After he throws a dagger, Alton then moves down 10 feet into the passage opposite Gotur.

Attack: 22 Damage: 4

Sneak Attack: 3

Alton, your dagger flies through the air, and with such a large target, it was pretty hard to miss. The dagger embeds itself into the ogre's fat right up to the end of the handle. Puzz oozes out. (-8) You then move down behind the half-orc. (make sure you roll your attacks with advantage as the ogre is stuck in the passageway! Sneak attack is valid)

Thorvin, seeing the ogre stuck like a cork, swings his warhammer as hard as he can towards the thing: Attack: 10 Damage: 6 the hammer doesn't hit the ogre as well as Thorvin was hoping, but it lands nonetheless. (-6)

Next Round: Zombie Ogre > Gotur > Alton > Thorvin > Venovar

The ogre looks bad with numerous large wounds, but is also still looking very angry. It tries again to swing its huge morningstar at the dwarf with difficulty since it's still corked in the passage: Attack: 17 Damage: 18 the weapon smashes hard off of Thorvin's armor and shield, but doesn't seem to pierce through. 

Gotur > Alton > Thorvin > Venovar are up!

(EDIT - Thorvin's attack was only with one hand because he has his shield equipped. So this is his updated damage roll. 5), so, -5 instead of -6.

Since you said he was in the doorway, I'm going to make an attack with advantage. Correct me if I'm wrong, and I can reroll.

Attack: 15 Damage: 12

Gotur thornwhips again and gets out of Alton's way. Attack: 17 Damage: 4

(Sorry for the delay!) 

Alton will move past Gotur up 10 feet to throw a second dagger before continuing upward in the passage about 5 more feet.

Attack (Advantage): 20 Damage: 5

Sneak Attack: 1

Gotur, the thorn whip lashes once again upon the ogre's back as some of its loose flesh explodes off. (-4)

Alton, your second dagger lands just like the first one did, although this one sticks in farther, you can barely see the tip of the handle since it's embedded deep within the ogre. It likely hit a vital organ. (-13)

Thorvin, swings his warhammer with one hand again and yells "He's lookin' worse for wear! Let's keep goin' lads! I'll finish him off when it's time with magic so he stays dead!" Attack: 20 Damage: 4 and the warhammer slams violently into the ogre's huge body. It is looking helpless now, stuck in the passage getting destroyed. (-9)

Venovar, your halberd again plunges deep into the ogre's fat body. Some guts come out and hang from the weapon as you retract it. (-12)

Next Round: Zombie Ogre > Gotur > Alton > Thorvin > Venovar

The ogre zombie is looking bad. It's still stuck in the passageway. Slabs of fat are hanging off, it has many gaping open wounds and a few daggers are stuck in it. It brings its morningstar up perhaps one last time and tries to crush the dwarf: Attack: 11 Damage: 11 the zombie can barely pick up the weapon now, and it slams harmlessly off of Thorvin's shield.

Gotur > Alton > Thorvin > Venovar are up! 

Gotur keeps trading off positions with Alton so they can get their cracks in on the ogre.

Thorn Whip Attack: 21 Damage: 1

Alton will use his movement to run up to the Ogre (I think he can make it), before savagely striking the fouls beast with both Shortswords.

Attack (Sneak Attack): 17 Damage: 15

Attack: 16 Damage: 2

Venovar will attack again.

Attack: 25 Damage: 22

Gotur, the thorn whip hits although doesn't seem to hurt the zombie as much as the last thrashing. (-1)

Alton, you burst forward into the small room with the ogre and let your short swords fly. They flash in the air and come into the ogre's midsection. The first attack opens its abdomen... (-10) -> undead fortitude (15 DC): 20 and the zombie manages to hold its guts in its body. Then the second sword opens up a different part of its gut (-3) -> undead fortitude (8 DC): 9 so the zombie is struggling to hold its intestines in its rotted body but manages to do so and remains standing.

Thorvin casts his holy sacred flame as it covers the zombie's body: 7 needs 13 DEX save: 5 and that's it. The ogre zombie drops to its knees as the morningstar falls to the ground along with its intestines. The zombie cannot tolerate the radiant damage of the flames and it eventually lies still in its own fat and guts. 

Venovar I think might still attack the disgusting thing out of pure rage as his halberd just makes the disgusting looking thing even worse. 

Combat is over. The ogre zombie lay still. 

What would you like to do?

Gotur backs out, not so keen to climb over the steaming pile of ogre, and heads down the tunnel to rejoin the others the way we came in, grabbing the well hacked body of the necromancer on his way.

Once he gets back to the main room, he'll check the body for anything. 

Investigation: 17

Alton will slowly trudge after Gotur, cleaning his swords of gore as he follows.

"I couldn't have done this without you, my friends. Thank you." He then looks around the room to try to get an idea of what the necromancer was doing or planning to do. What check would I do?

(sorry guys, busy weekend!)

Gotur, you bring the necromancer's body into the main room. The head remains in the passageway :) You check the body once you are back in the main room, and find one scroll of animate dead on his person.

Alton, you follow Gotur back into the main room as you clean which is a ton of gore from your swords. 

Venovar, you take a look around the room. You see bags of various body parts everywhere, bags of garbage, and barrels and boxes of god-knows-what. It looks like something out of a bad horror movie. At first glance, it seems this necromancer was a very sick individual. He was clearly crazy given his reactions earlier and then this cesspool.

There are also 2 chests in the room up against the north and west walls.

There is also a smaller room which looks like a sleeping quarters to the SE corner of this main room.

Venovar (or whoever might want to check the smaller room), please make an investigation check. Thorvin would cast guidance, so make the roll with advantage!

 Gotur scents the air, but doesn't have the wolf nose to tell if there are any mimics about.
