The sycamore seedling on Crannoc's shoulder wobbles, but then steadies as he is able to maintain concentration on Silvanus' Blessing.

DC 10 CON Save:  10 on the nose plus 3 from Bless so 13 succeeds.

Gallant grits his teeth with the attack but is able to avoid any additional damage and is able to keep concentration on the glow. 

Her predatory instinct triggered, a surge of adrenaline compelling her, Hildr pursues the fleeing bandit up the outcropping like a cat chasing a string. “Tempus drive my hungry blade home!” she shouts as she swings at her quarry.

Movement: 20 ft directly east (5 ft of which are assumed difficult terrain, for 25 ft of movement used), putting her in the square above the fleeing bandit
BA: Rage
A: Attack with Viking Sword: 13 + 2 (Bless) + 4 (Bardic Inspiration) = 19 total; 6 slashing damage + 2 Rage damage bonus = 8 total

Note that Hildr now has resistance to bludgeoning, piercing, and slashing damage.

Watching the group before him fall to the spell, Gawain turns to follow Hildr, hefting his glaive as he sprints after the raging warrior. Polearm twirling in his hands, he slings the blade in a vicious uppercut against the crossbow wielder. He lets the motion follow through, grip sliding up the shaft so he bring the blunt end of the polearm to bear on Hildr's target.

Movement. 5ft. East -> 20ft Southeast(difficult terrain assumption) -> 5ft East
Action. Glaive Attack to Hit: 7+4  = 11 Damage: 9
Bonus Action. PAM Glaive Attack to Hit: 23+4 = 27 Damage: 5

Hildr's blade catches the man across his back as he flees, sending blood through the air as a deep gash is cut. The bandit wielding a crossbow  is able to just barely dodge the blade of Gawain's glaive - his companion is not so lucky, as the polearm is whirled around and cracked across his skull. Bleeding from the back and now his head, the man falls to the ground.

A sixth bandit breaks from the treeline. With a crossbow raised, he sends a bolt streaking through the air at Gawain.

Crossbow Attack Roll: 20
Crossbow Damage Roll: 4

Order -> Crannoc followed by Gallant

Crannoc sighs, almost disappointed in the pack tactics of the bandits.  Should not the pack leader have coordinated the crossbowmen from the tree-line with the scimitar-wielders behind the logs rather than coming at the party disjointedly?  Unless perhaps this is just the leader testing the party before attacking in force.  Though that would be something few beasts would do - being more of a humanoid approach...  Might be more than meets the eye...

He rouses himself from his ruminations in time to amble south 25' and stand just southwest of Gawain, leaving room for Hildr to squeeze through between them diagonally if she wishes.  He speaks a simple word in Sylvan and a thorny green vine suddenly uncoils from his free hand.

Action:
Crannoc Thorn Whip to hit southernmost bandit:  22 + 2 from Bless = 24 (melee spell attack with range 30')
Crannoc Thorn Whip magical piercing damage:  4
Forced Movement on hit:  target is dragged 10' towards Crannoc, so north-northwest 10' north and 5' west (no saving throw)

Bonus Action:
Crannoc telekinetically pulls the bandit he just hit with the Thorn Whip 5' closer yet to himself.  DC 15 STR Save or be pulled 5' further northwest.

"When challenging the warriors of our pack, it does not do to skulk in the shadows, despite being named the 'Sunless'.  Come.  Let us see your face."

Seeing that many of his party bravely runs into battle, Gallant reach’s to his back and realize how much he wishes he had a cross bow. 

Gallant then runs to the closes bandit does the dodge action 

Bandit (F) Str Save: 5

The vines wrap around the bandit, piercing his skin as he's pulled towards Crannoc. He tries to resist against the unseen force pulling him even further by falters, stumbling along until he's well within the reach of both Gawain and Crannoc.

The other bandit throws his crossbow to the ground, brandishing a scimitar that he swings in an arc towards Gawain.

Scimitar Attack Roll: 13
Scimitar Damage Roll: 5

Order -> Iris followed by Hildr followed by Gawain

Irisviel takes a parting glance at the three unconscious bandits before running east, climbing up the rocky terrain to stand next to Hildr. With a quick arcane word and a flicking hand motion, she sends a bluish-white beam towards the bandit engaged with Gawain.

Hildr moves behind the bandits and, in an attempt to turn their attention to her, utters an ear-splitting shriek. She then swings at the bandit with the scimitar.

Movement: 20‒25 ft directly behind both bandits (5 ft of which might be difficult terrain through a bush)
A: Attack with Viking Sword: 13 + 1 (Bless) = 14 total; 4 slashing damage + 2 Rage damage bonus = 6 total

Note that Hildr has resistance to bludgeoning, piercing, and slashing damage.

Weapon still whirling in his hands, Gawain winces as a burning sensation tears through one the gaps in his armor. Eyes on the bandit Crannoc so graciously brought within his reach, he stabs outward towards the man. Pulling the polearm back, his glare turns to the bandit who managed to get past his defenses, spinning the glaive around to whack him with the blunt end.

Action. Glaive Attack to Hit: 16+4  = 20 Damage: 4
Bonus Action. PAM Glaive Attack to Hit: 10+1= 11 Damage: 7

Both bandits flinch when Hildr lets out a shriek behind them, visibly shaken by the warrior's ferocity and rage. As they're both badly wounded by attacks from Gawain, Hildr, and Iris the one still wielding a crossbow throws it to the ground, kneeling down and holding his arms above his head. "****. Alright, I'm done! Spare me, please!"

Order -> Crannoc followed by Gallant

Crannoc tries to think of animals who exhibit such quick and complete transitions from bravado and cruelty to abject groveling.  Monkeys perhaps?

Action:  (OOC:  EXACT same rolls as last time on all dice)
Crannoc Thorn Whip to hit bandit who has not surrendered:  22 + 2 from Bless = 24
Crannoc Thorn Whip magical piercing damage:  4
Forced Movement on hit:  target is dragged up to 10' towards Crannoc, ending up right next to him.)

Bonus Action:
Crannoc telekinetically shoves the surrendering bandit face down (prone).  (Maybe) a DC 15 STR Save (if bandit resists).  (Technically, his telekinetic shove can only pull or push a target, not shove prone but Crannoc assumes the surrendering bandit is not resisting and allowing himself to be pushed down.  So maybe if he does resist, he succeeds, but Crannoc would then immediately announce that he hasn't actually surrendered...)

Crannoc's voice is conversational and not at all hostile, its tone almost childlike and curious, at odds with Hildr's yell and his own attack.  "Interesting.  it seems a little late to show your belly now, but I have much to learn of your pack.  Tell us true then, are there any others hidden in these trees?"

Still concentrating on Bless.

Gallant continues to sprint up into the action realizing that by the time he got there everyone had done their thing. Trying to not look like a coward himself, Gallant says in an intimidating voice, “Why shouldn’t we just kill you right here and now? You grovel but we know that if we show you mercy you would sooner out in arrow in our back. Also I was hoping to fry something today!” His hands begin to crackle with blue electric energy.

Intimidation check 14 

Crannoc's Thorn Whip is more than enough to send the remaining hostile over the edge. Freezing from Irisviel's spell and bleeding from Hildr's blade, as the thorny vines wrap around his neck and tighten his legs give out. The bandit falls to the ground unmoving.

The other doesn't resist the invisible force that forces him onto his belly, he still holds his arms outstretched. He turns his head to look at Gallant as he marches up, but even after the bard's electric display there's none of the fear he seems to have for the other three. "We haven't even killed anyone, gods I swear! Most people just give up their stuff immediately, and those that don't give in after a little bruisin'."

(Since the other three are unconscious, I'll go ahead and move us out of initiative order for now. Iris would be know that spell only has a limited time left however.)

Cognizant that the others might not appreciate a proper interrogation, Hildr puts a foot forward. With it, she applies pressure on the knuckles of the right hand of the bandit lying with his arms outstretched. "I suggest you listen to our skald. Answer any questions he or anyone else poses to you. For the sake of my comrades, I'm going easy on you. For now. Trust me, I'm capable of much worse."

Help for Gallant or anyone else who wants to do another Intimidation check, DM permitting.

Confident that even Hildr alone could deal with their surrendered bandit, Gawain turns and slides back down onto the road. Laying his glaive on the ground and slinging his pack around he starts rummaging through it. "Iris," he calls over his shoulder. "Want to give these three a look over while I tie them up? See if they have anything useful." He pulls out a coiled up rope, uses a dagger to cut it into sections, then gets to work tying up the three unconscious bandits before they wake. 

Looking at the rest of his crew, "We should tie everyone up including the sleeping folks, I will talk to our new friend here." 

Turning back to the bandit, "Why do you tell me everything you know about the sunless gang and your weakness and I won't ask my friends to slight your throat." He finishes that statement with a sly smile. 

Gallant is summoning his Bandit King persona so could this be a performance with the help action?

Performance w/adv 14 + 3 = 17

Intimidation w/adv 12 + 3 = 15

Crannoc, seeing what Gallant is trying would have called for Silvanus' Guidance, tapping the genasi on the shoulder.  (Add 1d4).

For the most part, he would sit back and observe these interactions between the party and the captive bandit(s) with great interest.  As a zoologist might when observing unfamiliar animal behavior.
