All four creatures hit by the blast endure the full force of it, and one of the zombified gnolls collapses with a final wheezing cackle.

Veldruk, you're up!

Actually... it's just occurred to me... the gnolls are currently standing upon a suspended wooden platform, which has just been targeted by shatter. Doing some quick calculations... 

The surface of the platform splinters and cracks under the force of Evelyn's spell, but stays intact. However, another spell like that, and more likely than not it'll end up breaking to pieces.

OOC: Somebody kill that frickin gnoll!

Veldruk's blade bites into the gnoll's side, and it howls in pain as thunderous energy surrounds it. 

The last remaining zombie uses its action to climb up the side of the cliff, engaging with Nodjeim.

The gnoll hunter again attempts to stab at Veldruk, the booming blade preventing it from finishing off Evelyn. It actually manages to get a hit, dealing 6 piercing damage.

Chakka finishes off one of the gnolls, then retreats, leaping a full 30 feet up the cliff with their grasshopper-like legs. They provoke an opportunity attack, dealing 4 damage.

Nodjeim, Olan, Threla, go!

Map:

With the ogre currently out of site, Olan takes aim at the remaining gnoll- thing between him an Chakka.

Attack Attack: 20 Damage: 5

He then starts moving to join Chakka, with the aim of taking out the things taking on the main party.

Olan would have sneak attack from advantage, rolls an 8 for extra damage. The witherling goes down.

Nodjeim and Threla are up!

Threla swings her rapier at the gnoll in front of her (Imagine after all that, I kill him). 13 to hit, 5 damage.

With a shout, she encourages Evelyn, casting healing word at 2nd lvl on her for 8 HP of healing "Take strength from this sub-par inspiring speech!"

OOC: Fingers-crossed for good dice luck!

Lets try those dice again

Rapier attack: 23 to hit, 4 damage

Healing word: 9 HP of healing

The gnoll takes the hit and nearly goes down, but stays snarling. Evelyn is rescued from the brink of death.

Nodjeim, your turn!

     Zombie climbs up, zombie gets punched.  Nodjeim starts attacking even before it finished climbing up to his level, first spinning and slashing out at it with his spear and then following up with an unarmed kick to it's chest trying to shove it right back down off his level...  ((Bonus action Unarmed Strike not actually a shove but rather an attack, flavor wise just describing as a shove...))

Spear Attack:  17 to his for 12 piercing damage

BA Unarmed Strike:  19 to hit for 7 bludgeoning damage

The first hit takes down the zombie, so the second is delivered to the gnoll. It stays up, but barely. Looking up the stat block to see if I can give you any cool disease... nah, Nodjeim is fine. Is also the thing he is, so that doesn't really matter anyways. 

The remaining gnolls attack Nodjeim. One hits, dealing 5 damage with a spear. The other one again fails to hit him with an arrow.

The remaining witherling begins climbing up the hill after Chakka. It manages to climb up to them, but has to dash to do so. 

The ogre takes an action, but is out of sight, so no one knows what it is.

Evelyn, Veldruk!

Map:

Ironically, he felt relief when the gnoll attacked him. Under better light he could see clearly the movement of the creature. So much so, that for a moment it was possible to read what it was about to do. With his sword rather than his shield, Veldruk deflected the strike. Threla’s words suggested the casting of a spell and that inspired him. Booming Blade was created for that situation, after all, a melee confrontation with an enemy one didn’t want to move.

Whispering arcane words the warlock wielded his weapon. His movement drew an arc of steel through the air and cut through flesh. A favor the target was fast to return. A quick stab, quicker than the drow could block. For a moment he considered using shield, but the ogre was nowhere to be seen. A harder fight where such defense could be more necessary was bound to happen, so he decided to take the wound.

“You undersell your speeches.” He said to the bard, channeling into his arm the strength she gave him. Under his breath the fast chant of a rudimentary if not already familiar spell could be heard and once again his weapon was encased in thundering energy. An attack followed fast, determined to bring down the persistent enemy.

Notes: The lowering of the guard was just a description for moving the shield from the front of the body. Flavor that I never expected to have any effect on the combat, but thank you for the positive interpretation. I really liked the idea of the contested roll to draw aggro. This round Veldruk uses Booming Blade again, spending the inspiration Threla gave him to make sure the attack hits (17 to hit + 3 from inspiration, 12 slashing damage + 3 thunder damage if the gnoll survives and moves).

The gnoll goes limp as Veldruk's sword spears through its stomach and crushes its vertebrae. It stands for a second more, then collapses as the blade is withdrawn. As it collapses to the ground, the magical energy encasing it shoots inward with a sound like a thunderclap, and there is a horrible crunch as every other bone in its body collapses in on itself. The holy gnoll is dead. Finally.

Evelyn, your turn.

(On a side note, today marks one month of waste-wandering, gnoll-shanking shenanigans!)

OOC: YES! The god-gnoll is dead. Humbug, maybe that should be a new monster you make: A gnoll blessed by the powers of fate. Actually, on second thought, don't.

OOC: Happy one month anniversary guys.

Evelyn will focus her energies on the gnoll that attacked Nodjeim if she can get line of sight on it. She unleashes three bolts of magical energy toward the creature, which slam into its hide.

Damage - 7

It goes down, leaving only one gnoll and the witherling remaining, as well as the now hidden ogre. 

Chakka neatly dispatches the witherling in combat with them.

I'm just going to say that whoever posts next can narrate how they kill this gnoll. It has ten hit points, one attack per round, and a pretty bad modifier to hit. Not to mention that it's been attacking Nodjeim, who has one of the highest ACs in the party, plus the ability to just catch arrows, which the gnoll doesn't know because it hasn't hit him yet. The ogre will keep on taking actions, but they're out of sight, and he's not coming out of the house. 

Combat end!

With the combat over, Olan moves to a position where he can watch the house entrance, with a barbed arrow nocked, in case the ogre makes a break for freedom.

(Anyone going to do anything else?)
