(Guessing stealth is no longer an option, unless this is a group check, and we can offset the 5 from above...)

Rubin Stealth: 24 Guidance: 3

(Probably not with Xan, but will try. Next time I'll remember to use Pass Without Trace.)

Xanranzan Stealth: 9.

(This is a group check, yes.)

Stealth: 14 for Sorak

The group just barely manages to stay quiet enough to gain the drop on the occupants of the room.

Kethra, you see 5 of the reaver types lounging around on beds or chairs, as well as a priest sitting apart from them.  They all scramble for their weapons as they see you, but aren’t quite fast enough.

(Initiative, you all have a surprise round)

Even though she was trying to be stealthy, the pale-eyed shieldmaiden nearly threw the door open with a loud bang only to be saved by Rubin's intervention.

"Hehe...thanks. Still getting used to this shield."

Initiative: 10

If she's allowed to, Kethra will attempt to steal the weapon off of the nearest reaver who hasn't reached their weapon yet, then make her way to the priest with her 40 ft of movement (since surprised enemies don't have reactions, they can't make attacks of opportunity) and tries to tackle him.

Athletics check: 22

Rubin initiative: 23

Rubin shoots at the priest first, then moves to the others if the priest goes down...

Normal action To hit: 19 Damage: 4
Bonus action To hit: 27 Damage: 8
Dread ambusher To hit: 9 Damage: 9 Plus 3

Tyde's Initiative: 11 

(Not sure of how big the room is or where all the reavers are in relation to each other... but Tyde will try to catch as many as he can in his Web spell.)

Tyde will cast Web to ensnare as many of the enemy as he can.

Xanranzan Initiative: 17.

Xanranzan goes after one of the closer reavers in hopes of avoiding getting caught in any webbing. If he cannot do so, then he would clang his weapons together, amplifying the ringing to deadly levels for a few. Regardless of what future comes to be, the grinning Earth Genasi was ready to pay back some mother truckers for the accommodations.

Action: Attack w/ Shortsword directed on nearest Reaver from door.
To Hit: 12 For: 8 piercing damage.

Bonus Action: Off-hand Attack w/ Javelin on same Reaver(if not dead).
To Hit: 16 For: 4 piercing damage.

If hit at least once, 1st to hit does an additional 5 damage and same rolled number gets added to Xan's AC from Defensive Flourish.
Or, if there's two Reaver's within 5ft of Xan, using Slashing Flourish instead to deal rolled damage to both 2ndry target and initial target.

------------
If at risk of being caught in Web however, casting Shatter(Con 13) instead on as many Reavers possible within 10ft of each other. 17 Thunder, or half as much on success.

(I’ll update tomorrow, busy tonight.  The webs would cover most of the room.)

(Okay, then shatter it is! Updating my sheet!)

Ooh, if we're updating things, then Kethra will also punch the priest as a bonus action martial arts

To hit: 25 Damage: 5

Edit: Critical hit damage lol 1

Priest init: 

‘Reaver init: 7

Saves: 6, 8, 2, 12, 12

Priest init: 7

Sorak will summon his bonded weapon to him as a bonus action, and lay into the priest.

Attack: 9 Damage: 22

The priest curses, and seems to blur.

The reavers scramble to grab their weapons, wasting their turns.

(Everyone is up)

Rubin shooots at the priest again...

To hit: 13 Damage: 7
To hit: 16 Damage: 5

He then steps out of the way of the door and off to one side, outside of the room and out of view of anyone inside.

Tyde will cast Acid Splash at 2 of the reavers if they are within 5 feet of each other, otherwise just one of them.

DEX save vs. DC 14 or take 4 acid damage. (each if 2 targets)

Xanranzan strikes his weapons together again, amplifying and detonate another blast of deadly vibrations. This time if he can catch a reaver and priest together in the spell without harming new found friends, then he does so. But if not, he goes for the largest clumping of reavers.

Actions: Cast Shatter(Con 13) at 2nd level, inflicting 20 Thunder Damage. 1/2 damage on a successful save.

Xan can get 3 reavers without hitting any allies.

Acid saves: 19, 13

One dodges the glop, but the other screams and falls dead.

Shatter saves: 20, 19, 17

Rubin lands 2 shots on the priest despite his blurred form.

Conc: 17, 15

Two more reavers drop dead, the other barely holds on.

Athletics: 9

Kethra successfully grapples him.

Web saves: 4, 7

Triumphant for a moment, the pale eyed girl manages to snatch her target, getting caught up in the crossfire of spells.

"Where's the Silver Watchtower?!"

DEX save against the Web that's now everywhere: 20
