Elandra weighs the options in her head, knowing how close the creature was to hitting Jade and how hard they hit against taking her chances to put one of the creatures out of the battle entirely. "Lux, can you help Soloth and Koric, we'll keep this at bay." Elandra returns to the refrain, repeating her actions, looking at the bulette engaged with Jade and uttering words of discouragement, "Back off, go crawl back under a rock and chew on some moss."

Action: Vicious Mockery DC15 WIS, save negates 5 psychic damage & disadvantage on next attack.
Bonus: None
Movement: None
Reaction: Cutting words - if bulette #1 looks likely to hit Jade (die roll of 16-21)

@Koric

You again burn the second bulette with Balthar helping you distract it, which looks to be on its last legs at this point

@Elandra
Wisdom Save: 13

@Elandra
The bulette in front of you again looks deeply insulted and hurt, almost moping about as you insult it. You also ready your cutting words in case it tries to hit Jade

Lux acknowledges Elandra's request and moves to help Soloth and Koric. He says loudly "Everyone, close your eyes. It's about to get very bright over here" He moves as close to the other bulett as possible (melee if possible). He then holds his staff up high and calls forth the Radiance of Dawn upon the bulette. 

CON Save DC 16

Damage: 15

End turn

Con Save: 20

@Lux

You attempt to blind the bulette with the light of Lathander, calling upon the radiance of the dawn, but it resists the light, averting its eyes to avoid any damage

(Half damage on save)

As Jade can tell that the bulette in front of her is badly hurt, she switches out her glaive for her blood spear and attacks.  Aiming at it's huge mouth she thrusts the spear towards it.

Attack: 21 Damage: 6

Attack: 21 Damage: 11

She then spins it around and tries to beat it over the head with the blunt end

Attack: 21 Damage: 5

@Jade

Your first attack just barely misses, but the other two blows land, sending the wounded bulette reeling. It again attempts to bite at you despite Elandra's attempts to weaken it 

Attack: 9 Damage: 26

@Lux

As you fail to hurt the bulette with the blinding light of your god, it turns you in anger, biting at you with its massive maw

Attack: 18 Damage: 14

Updated Map:

@Jade and Lux

Jade, the bulette you have been fighting misses you wildly in its highly weakened state, but Lux, the bulette you tried to attack sinks its jaws into you, albeit without much force 

Liri, you are up!

Lux reacts with a Warding Flare

(When you are attacked by a creature (that can be blinded) within 30 ft. that you can see, you can use your reaction to impose disadvantage on the attack roll.)

Rolling second attack roll (as if it was rolled with disadvantage originally): 15

@Lux

Your blinding light distracts the bulette for just a moment, long enough for you to dodge out of the way of its bite

Quote from Ereshion >>

@DM: So...new round, I think? What's the stats of each creature?

 

 After Liri makes her move, it will be a new round, yes. I can't give you exact stats but both are highly wounded

Seeing the heavy wounds of the creature, Liri summons her flames again. While she would hope to drive off any creature where possible, she realises that these bulettes are not likely to back down - and it is a matter of survival. She hurls the fire at the wounded bulette that is continuing to attack Jade.

Produce Flames: Attack: 15 Damage: 2

@Liri

You attempt to fling a flame at the first Bulette again, but it bounces off of its rocky carapace, unable to harm it further

@Soloth

You hit the bulette with a heavy blow, fueled by your magical knowledge of its weak spots, but your second blow misses by the slightest amount. The bulette looks seriously on its last legs at this point

Elandra, you are up!

(Posting now as I'm about to head to bed)

Jade happily evades the attack from the wounded bulette and retaliates with her blood spear trying to strike the beast down.

Attack: 17 Damage: 6

Attack: 18 Damage: 4

And spins the weapon around for the bludgeoning damage..

Attack: 7 Damage: 6
