Kaylyn curses under her breathe as she wastes her spells on an illusion.  But with the aid of the daylight spell she now has a good idea where the true made is.  With Pensive's help she refocuses her Eldritch Energy where she believes the true drow mage to be.

Attack: 13 Damage: 8

Attack: 28 Damage: 7

She then calls to Sekkar "Gain strength my friend!" bestowing Bardic Inspiration on him as a BA

Rhayna is concerned that they might be attacked from behind by those aberrations. She takes a step back to be next to Kaylyn, and casts Light at the bottom tip of her whip and hold it high. She hopes that will discourage the monsters from coming closer. "Kastix, watch out for those monsters behind us. You may want to come closer to the light." She yells to Kastix.

(Sorry, not much else to do while concentrating on Bless.)

She’s trying to get to where the invisible mage was...so, as close as she can. 

Rhayna's whip illuminates the area a little more, hoping to keep the creatures at the rear at bay. Pensive buzzes bravely around the area where the mage was, using his keen smell and hearing to hone in on the invisible drow's location, eventually getting close enough to detect it with his blindsight, and transmitting this information to Kaylyn. She aims her blasts as best she can, narrowly avoiding Pax as she runs past, and...

concentration: 1, 20  (Christmas colors!)

... with a grunt of pain the mage pops back into view, doubled over from the force of Kaylyn's blasts striking it. The other drow move in to protect the mage, focusing their attacks on Pax and Sekkar.

Drow1 HXBow v Pax: Attack: 16 Damage: 5
Drow2 SSw v Pax: Attack: 19 Damage: 3
Drow3 HXBow v Pax: Attack: 8 Damage: 4

Drow4 HXBow v Sekkar: Attack: 23 Damage: 5
Sekkar, if this attack hits, make a DC 13 Constitution saving throw or be poisoned for 1 hour.

Zeno's turn

Kaylyn, Rhayna, D1-4, Zeno, D5, Sekkar, C1, Kastix, D6, Pax

Sekkar Con save: 17  (phew! can keep Bardic Inspiration which stuck with the Bless, right?)

Quote from BlueBayou >>

Sekkar Con save: 17  (phew! can keep Bardic Inspiration which stuck with the Bless, right?)

 Sure does

Zeno reloads, shifting his aim toward the dangerous looking Elite engaged with Sekkar.

Attack: 21 Damage: 10

Bless: 2

Sneak Attack: 13

Zeno's bolt this time finds a gap in the drow's studded armor, but the elite warrior is too disciplined to allow it to affect his battle prowess. With a slight movement to put Sekkar between itself and Zeno, the drow protects itself a little from further projectiles and also prevents Sekkar from advancing on the mage. It then engages in some rather skillful swordsmanship, seeking to strike a blow on the lizardman...

 Elite: SSw v Sekkar: Attack#1: 17 Damage: 8 piercing plus 17 poison damage
                                    Attack#2: 12 Damage: 8 piercing plus 8 poison damage

Meanwhile, the flying creatures at the rear linger just outside the aura of light, seemingly unwilling to enter. Their hunger and frustration manifests in deep echoing unerthly moan that resonates through the cave, but is particularly chilling to Rhayna and Kaylyn.

Rhayn/Kaylyn: Make a DC 13 WIS save.

I decided to slip in the cloaker's turn to speed things up. Now it is both Kastix's and Sekkar's turn.
The drow elite has moved one space 'north', and the cloaker(s) has also moved slightly. Otherwise, no change to the map.

Kaylyn, Rhayna, D1-4, Zeno, D5, Sekkar, C1, Kastix, D6, Pax

The drow had to work harder to get trough Sekkar's defenses. And lizardman did nto complain about target switch either - there were enough people to take care of illusive mage.

BA: Activation sword (more day-light on the floor)

Attack drow warrior: Attack: 20 Damage: 13 (+Bless to attack 4 )

                                     Attack: 17 Damage: 17  (+Bless to attack 3 + Bardic Inspiration 6 )

Rhayna WIS save: 21

Moving in closer to get better scope and range, Kastix takes aim and cast Scorching Ray onto the Mage once more, three rays into them.

Attack: 20 Damage: 8 Fire

Attack: 26 Damage: 10 Fire

Attack: 28 Damage: 14 Fire

Sekkar sends the mental message to Dawnbringer to activate, and he is relieved when the blade of light emerges from the hilt as before. No words come from the sword into Sekkar's mind, but he receives several emotions: jealousy at the light spell from Rhayna, resentment at the threat of abandonment, lingering indignation at not being listened to, but all tempered by the undeniable joy of battling these dark creatures. Even Rhayna's light didn't have the effect on the drow that Dawnbringer does, and the drow warrior cowers away from the sudden glare, affecting his ability to parry Sekkar's blows.

Meanwhile, Kastix shoots forth more rays of flame at the mage. It again attempts to raise a magical shield against them, but the tiefling's magic is too strong. All three rays blast right through the shield and burn through the mage's robes, and with a rather girlish cry the drow falls to the ground.

Pax/Rhayna/Kaylyn are all up. Still need a WIS save from Kaylyn 

Kaylyn, Rhayna, D1-4, Zeno, D5, Sekkar, C1, Kastix, D6, Pax

Pax looks at the fallen mage, then turns her attention to the warrior battling Sekkar.  She approaches him, her sword swinging. 

Attack: 23 Damage: 4 + 5 thunder damage as her weapon is coated in booming energy. 8 damage if he tries to move on his turn. 

Opportunity attack from Drow2 on Pax: Shortsword: Attack: 16 Damage: 8

Wis Save 18

Now that the Drow mage was dead Kaylyn shifts her attention to the drow that is fighting Sekkar and again Pensive helps by sending various conflicting emotions at the drow to help distract him.

Attack: 18 Damage: 12

Attack: 16 Damage: 7

"Hold strong sister!" Kaylyn yells as she gives Bardic Inspiration to Pax

Seeing that the mage is down, that tide of the battle is turning, and that he is beleaguered with foes, the drow warrior calls out to his companions in Undercommon: Ihes egin. Bidali hitza andreari. Hemen atzeratuko ditut. ("Flee! Send word to our mistress! I will delay them here.") The four other drow turn and flee back up the tunnel...

Zeno next. Didn't get an action yet from Rhayna either.

Kaylyn, Rhayna, D1-4, Zeno, D5, Sekkar, C1, Kastix, D6, Pax

Rhayna will take the Dodge action, in case the abominations behind the party change their mind about attacking the party. "Shooo!!! Go away!! There is nothing here for you!!"

(OPS!! I am really sorry for missing the post.)

(Skipping over Zeno for now)

The drow warrior seems to be changing tack, and simply fending off the blows from the surfacers, trying to buy time for his comrades.
(Dodge action - attacks against Drow Elite have disadvantage)

The swooping creature at the back makes no further attempts to approach.

Everybody now!

Only change to previous map is that the other drow are all 60' ahead of Pax. They are still within the Daylight spell though, so still visible.

If the drow was buying time for his fleeing comrades, Sekkar was happy to entertain the slaver, while others take care of the runners from afar. The drow was fast, but the light from Dawnbringer was still shining and even if it was difficult for Sekkar to hit, so it was for the drow (should he stop dancing and begin to fight again).

BA: Hunter's Mark (moved from the dead mage?)

Attack: 29 Damage: 10 

Attack: 13 Damage: 11

DA attacks rolls: first 23 (+4 to damage if hit) second 25 (+2 to damage if hit)  Forgot Bless :) 1 and 2 to attacks )

Rhayna will take the Dodge action again. This time, she will yell at the creature in Undercommon to go back where it came from.
