(Misty Step is just a bonus action. You could hit him with one of you cantrips that cost an action.)

(Realized that, changed it to include a cantrip action as well. Again, sorry for the delay and all this mess.)

(No worries you're good!)

Laucian: You take one look at the Solar and vanish in a puff of silver mist, reappearing 30ft away next to Gilra.

Wisdom Save for the Solar: 32

Your Mockery takes no effect, but thanks to you quickness you are out of the way for what happens next.

At the end of your turn, the Solar uses its last two legendary actions to make a Searing Burst. There is an explosion of fire and radiant light that encompasses everyone within 10 feet of the Solar. I need Dex Saves from Barosh and Valrakus. 

Remember you get +5 from Mankur's aura

Barosh Dex Save: 15

(Is that a spell or an ability, asking for future reference of using counterspell)

Quote from Persuasion >>

Barosh Dex Save: 15

(Is that a spell or an ability, asking for future reference of using counterspell)

 This is an ability.

(I'm in the middle of my live game right now, but if we don't have the other save in a couple hours I'll have to make it for them. I don't like doing it in case I roll badly, but also want to keep the game moving :(  )

Okay to Keep the game moving I'm going to make Valrakas' save for him-

Valrakas Dex save: 25

Okay! Valrakas passes but Barosh fails. It's full damage on a fail and half damage on a pass

Radiant damage: 12   Fire Damage: 19

That brings us to the Devas

The Devas, who are heavily injured, reach out and join hands. A soft light eminates as they use their Healing Touch ability

 For their movement (they have 90ft flying speed): Two Devas move into melee with Archy; Two move into melee with the shadowy mass that is Ileanys, and three move into melee with Mankur.

Synoptic Static Saves under the spoiler below (the stuff under spoilers isn't secret, it's just in there to try and shorten the post.

 That finishes their turn and brings us to Ileanys.

Ileanys: Deva's #3 and #4  are in melee with you. #3 is more injured but they did both just heal. The Solar has teleported and is now 15ft behind you.

Ileanys flies away from the 2 angels next to him, turning in the air to fire 4 bolts from his crossbow back at the one that looks more injured.

(Move 60 feet away fromt he angels, in whichever direction puts me furthest away from any enemies.  Umbral sight makes me invisible while in darkness to creatures that rely on darkvision to see in darkness, in addition to being heavily obscured by Shadow of Moil, so no Opportunity Attacks from the angels when I move away.  Dread Ambusher lets me take an extra attack if I take the attack action on the first round of combat and adds 1d8 damage to it if it hits.  Bonus action for one extra shot with Crossbow Expert.  All with advantage due to being obscured/invisible and an extra d20 roll on the advantage with elven accuracy.  And sharpshooter for -5 to hit and +10 damage on each.  Attacking the weaker one, #3.  If the target dies from one of the first 3 shots, rest will go after #4 instead.)

Attack: 22 Damage: 19 +5 necrotic damage from Lifedrinker

Thirsting blade second attack: 28 Damage: 19 +5 necrotic damage from Lifedrinker

Gloom Stalker extra attack: 25 Damage: 20 +5 necrotic damage from Lifedrinker

Bonus action attack: 30 Damage: 28 +5 necrotic damage from Lifedrinker

Forgot the extra 1d8 damge on the gloomstalker attack: 2

(And if I do kill one, use Accursed Specter to raise a Specter from it's spirit.  14 initiative unless you want it to just share mine.  8 temp HP and +5 to attacks and damage rolls)

AoO since Raze was back there. Adv from invisible, +5 damage from pally aura:

31, Damage 15

Raze: As the angels move away you strike out hitting angel 4  (That's going to be Deva 7 who takes the damage)

Ileanys: You fly backward, rapidly firing crossbow bolts as you go. You've spent years studying Celestial creatures, and know their weak points. On the third strike, one of the Devas that moved into melee with you falls, its body disappearing into a silver mist. You adjust your aim, and the fourth bolt slams into the other Deva's shoulder.

(Unfortunately Accursed Specter only works when you kill a Humanoid and these are Celestial, but your character would know that so the ability isn't wasted.)

That brings us to Mankur. Three of the Devas have moved into melee with you with their maces raised. (It's Devas #5, #6, and #7.  Deva #7 just took an AOO from Raze and is the most injured. The Solar is about 25ft behind you.

(If you do still want to use your channel divinity, give me a quick Religion Check first.  Actually scratch that. You are a level 20 Paladin and an Aasimar. You know that Celestials of this caliber are immune to fear.)

(Seeing as most of them have left my 30ft I won't)

As they surround Mankur he smiles before his eyes become pools of darkness and two ghostly skeletal wings pop out of his back

"Oh do come closer" 

Using Necrotic shroud

Then using Dread Lord shadow attack on the Solar

To Hit: 22

Damage22  (Necrotic Damage)

(OOC: Also the devas if without blindsight will have disadvantage on melee "Creatures that rely on sight have disadvantage on attack rolls against creatures draped in this shadow.")

Mankur:  Skeletal wings rise from your back and the light around you dims. You glance over your shoulder and the necrotic energy springs forward to strike the Solar. The strike certainly lands... but the necrotic energy washes over the Solar with seemingly no effect.

(All of you saw that, so as a group you have realized that the Solar is immune to necrotic damage.)

That brings us to Raze. There are two Devas in melee with Archy, three in melee with Mankur, a Deva who was in melee with Ileanys but is now on its own, and the Solar who is next to Barosh and Valrakus. With your crazy monk movement you can get into melee with any of them. Deva #7, who is in melee with Mankur has taken the most damage.

(The devas within melee need to make a CHA st dc 19)

(The devas within melee need to make a CHA st dc 19)

Sorry if I wasn't clear in my previous post and you thought I just meant the Solar, but all the creatures you are currently fighting are immune to fear. If that would have changed what you did on your turn feel free to choose a different action.

Going to attempt another compelled duel on the solar WIS st dc19

Wisdom Save for the Solar: 23

Unfortunately, it once again resists your spell. 

(Raze you're good to go)

With the pinging of metal on the stones, Raze chases after the one the monk struck as it charged Mankur. Unseen, a fury or staff strikes and kicks fly at the injured Deva (#7)

• Attack: 19 Damage: Unable to parse dice roll.
• Attack: 29 Damage: 16
• Attack: 29 Damage: 12
• Attack: 30 Damage: 15

(If that finishes it off and if  I have any movement left,  I would moove to the next nearest Deva. Also, if that finishes it I get 25 temp HP.)

(Sorry, I just have to ask because I'm not seeing it on your sheet. What item/ability are you using to remain invisible? You did use your reaction to hit a creature and normally doing something like that breaks invisibility.)

Level 18 feature

(GOTCHA! When I was looking that over I just saw the astral projection feature. Sage advice has clarified that Empty Body invisibility doesn't break on an attack. )

Raze: Still unseen, you ambush the injured Deva from behind. It is barely standing after the third hit and the fourth is needed to finish it off. It collapses in a burst of silver smoke and you feel its life essence bolster your own health.

Valrakus it is your turn. Right now you are in Melee with the Solar. It is looking impassively down at you with it's sword in hand. The remaining five Devas are in melee with your allies about 30ft from you.
