Setting The Trap

Dreli deftly scales the remains of the first Sweeper, and finds herself on the ground. Dani quickly approaches and gives a friendly smack on the back before rallying the nearby forces.

"You have two jobs folks... make sure Dreli has a clear path, and make sure Dreli is alive." An affirmative grunt is uttered by those around, and they work to engage the Sweeper in the front leaving a route for Dreli to approach from the side. Two of the first to run up are smacked away hard by the Sweeper, sending them airborne landing on their backs several feet back.

If Dreli wants to try sneaking up on it roll a DEX save. Success means you can attack rolling a D12 damage die, failure means it will get a hit on you but you can still roll a D8 for damage.

As Wenlan, Hilmir, and the rest of the group approach the Commander, barbed vines grow out of the ground and wrap themselves around Wenlan's arms and legs. Looking around she can see that the rest of her group is similarly constrained, several of them cursing as they struggle against the sharp restraints.

When the Commander walks within sight, two additional Robes can be seen on either side of him. One reading from a spellbook, another holding some kind of repeating crossbow. The Commander smirks as he looks over everyone captured in this web of vines, and instructs his cronies "Clean them up, I need to put an end to this."

He continues walking towards the direction of the pit and all the commotion, while two crossbow bolts fly into two of the men trapped in vines, slaying them. The vines constrict, and everyone still alive tangled in them takes 4 damage.

Please roll a STR or DEX save for Wenlan, and a STR save for the group, to get out of these vines.

Dreli takes advantage of the opening that the others created for her, and successfully strikes the Sweeper with the dark blade. It appears to be slowed as a result of the strike, meaning that any attacks on it for the time being will be considered enhanced.

Meanwhile the Commander walks up the edge of this clearing and surveys the scene, paying close attention to the fight between Dreli and the Sweeper. He mutters something under this breath while holding an amulet that he has around his neck, and the Sweeper makes a twitch and dives towards Dreli attempting to grab her.

Because it is slowed, roll two DEX saves and take the better one to avoid being grabbed.

Dreli evades the Sweeper's grab and delivers a significant blow with the blade. It seems to struggle a bit as it stands upright again, and one of the nearby men jumps on its back in an attempt at distraction. This backfires however, as he is unceremoniously thrown into a nearby tree.

Half of the remaining men on your side continue trying to engage this Sweeper, the other half start making their way over to the area with the barbed vines to help the others out.
------
Wenlan and the others fight against the vines, but their efforts just don't seem like enough. As the Robe with the spellbook maintains his focus and continues reciting the incantation, the constriction continues damaging everyone for another 1 point of damage. The one with the crossbow fires two more bolts, one slaying another target and the other hitting Hilmir who remains upright but looks quite hurt.

The last Sweeper enters the area, walks right by the pit, picks up a large rock and throws it right towards the Robe with the spellbook. He managed to jump out of the way, but lost his concentration ending the spell causing all of the barbed vines to wither onto the ground. Everyone tangled is free again.

"The next one won't miss!" a familiar voice bellows from the Sweeper's back. It is Tanya, and it appears that she's wearing one of the amulets which allows commands to be issued to the Sweepers.

Wenlan's attack catches the Robe off-guard and causes him to drop the spellbook on the ground. The Robe with the crossbow makes a run for it in the direction of the Commander, leaving his partner to contend with the resistance fighters encircling him.

He can see everyone closing in around, and takes out a dagger making a wild lunge in Wenlan's direction that does 5 DMG (Wenlan would only take 3 because of her armor).

Dreli makes another attack at the Sweeper's core, and it stalls for a moment before collapsing onto the ground. It still contains the power crystal, but doesn't seem like it will be getting up under its own power without some form of repair.

Panic rushes over the Commander's face, and he utters "Follow me, get the girl!" to the Robe with the crossbow. They make a break towards Tanya and the final Sweeper.

The Robe's lunge attack hits Wenlan hard for a moment, but she steels her nerves and stays on her feet. Hilmir bursts through the crowd and says "That was extremely unhospitable!" before driving him through with his sword. The Robe falls over slain, and Hilmir begins limping toward the direction the Robe with the crossbow ran, a bolt still sticking out of his side.
-----
The Commander holds his amulet and speaks quietly, before the last Sweeper grabs Tanya off of its back and tries to throw her into the pit. She manages to grab hold on to the side but can't quite pull herself up, while the Robe with the crossbow shoots towards the advancing group to try and lay some cover fire for the Commander.
