Ian and arafiel roll stealth checks please.

Tyrus focuses forward, hands clenched on the hilt of his sword, waiting for the sounds of battle to indicate his companions' stealthy approach has ended.

stealth5

well that happened

Ian sees Arafiel trying the be stealthy.  He moves away from him but attempting to get closer to the big orcs.

stealth check 22

As arafiel moves forward he trips on some broken branches.  Ian moves away from him and gets in position to range attack the larger Orcs.

The smaller orcs spot Arafiel and scream “travelers approaching.... get that little one before he gets away!”

All of the Orcs are now very alerted and looking around for other travelers.  Three of the smaller ones sprint towards Arafiel with weapons at the ready. (It will take two rounds before they are on him.)

(Ras by now is back with the larger Orcs, I assume)  "Just ignore that SWINE, his father was quit a BOAR anyways" He chuckles and continues "We best start gathering things to get back to that bridge"

Not sure what checks you want:

Deception: 24

Can I get to within 60 feet of one of the small ones running toward Arafiel?  If so, I'm taking a shot using the light crossbow, and using a bonus action to cast Spiritual Weapon (a five-foot tall version of Auril's holy symbol).

Light Crossbow: 8
Damage if applicable: 4

Spiritual Weapon: 17
Damage: 8 Force Damage

Ras will wait for an opportunity to surprise one of the larger orcs and attempt an assassination:

He will attack with his Rapier: 

Attack: 23   

Damage(Auto Critical):  10     Sneak Attack Damage:  17      Modifier: 4

He then takes his bonus action to change his appearance to match the Orc he just assassinated.

Ugh

Arafiel casts ICe Knife at the centermost Orc charging him  Attack: 10 Damage: 4

You create a shard of ice and fling it at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 piercing damage. Hit or miss, the shard then explodes. The target and each creature within 5 feet of it must succeed on a Dexterity saving throw or take 2d6 cold damage.    

DX save of 14 or 7

To Conalt:  you are too far away from him for that.  Maybe two dash actions could get you that close.

To Ras:  your deception worked but your sneak attack was not enough to kill the larger Orcs.

To Arafiel: Dexterity saves on the three orcs.

Orc 1 3

Orc 2 17

Orc 3 4

Initiative order going forward : Thagakh, Ian, Tyrus, Large Orc 1, Large Orc 2(damaged by Ras), Orcs 1-6, Ras, Arafiel, Conalt.

(Which orc is closer to who?)

The injured Large Orc is closer to you and Ras than the other Large Orc.  There are six regular size orcs between you and Arafiel.  Three of them are almost to him.  The other three are walking towards him.

The group of orc's assuming long lost wereboar cousin makes two cleaving strikes against the injured large orc using his magical greatsword.

Great Weapon Master, Feral Might, Biter Melee Weapon Attack: 3 Damage: 24 Magical Slashing Damage

Rite of the Storm: 5 Lightning Damage

Great Weapon Master, Feral Might, Biter Melee Weapon Attack: 9 Damage: 22 Magical Slashing Damage

Rite of the Storm: 4 Lightning Damage

The sneak attacks by Ras prepared the large Orc for Thagakh’s attack causing him to miss badly and throwing off his balance.

Focusing on the two Largest Orcs in the back, Ian notches an arrow in his longbow and fires.  Using the horde breaker skill he shoots his second arrow at the injured Orc.

Attack: 18 Damage: 8

Attack: 22 Damage: 11

Ian misses with his first shot but sinks the second arrow in deep forcing the Orc to the ground.

Seeing Arafiel trip, Tyrus abandons all stealth and sprints toward the orcs. 

Action: dash
