Xarkris takes the 7 points of slashing damage from the gorilla and now has 6 hit points left of his 39 max. 
Xarkris casts HUNTERS MARK and targets the Snake Statue as a BONUS ACTION.

My Vow of Enmity is still in effect, and I can still attack with ADVANTAGE

First Attack: I rolled (3,13) + 6= 19 TO HIT for 2+5=7 Points of slashing damage, plus 6 points of slashing HUNTER's MARK damage. 

Second Attack: I rolled (5,10) +6= 16 TO HIT for 7+5=12 Points of slashing damage, plus 4 points of slashing HUNTER's MARK damage.

END TURN

Sly’s fire bolt misses the gargoyle by a few inches, but Xarkris’ attacks with his axe against the snake statue are far more effective, as after a few fierce swipes, he’s able to topple it. 

Bilyur is up!

Initiative
Bilyur: 21
Daewen: 19
Gorilla Statue: 16, -8 HP
Mun: 13
Sly: 11
Xarkris: 10

[Map changes: Grung and Snakes Statues are now absent, Bilyur is 5 feet south and Mun is 5 feet north]

Bilyur, now nearly exhausted, simply points at the gorilla statue and channels his energy to summon a toll of the statue's soul. A bell tones out, sending a wave of darkness into the statue. The gorilla must make a DC 15 WIS save or take 22 necrotic damage. 

“Surrender, or know oblivion,” whispers Mun, her voice carrying, sibilant and wrong.

The gorilla statue gives a silent roar of pain as it is struck with the tolling of the bell, which deals a significant amount of damage to it [Wisdom Save: 3] Quickly, the gargoyle has gone from mainly unharmed, to showing cracks along its muscular form. A few good strikes with the right tool, and this battle could finally be won. 

Daewen is up!

Initiative
Bilyur: 21
Daewen: 19
Gorilla Statue: 16, -30 HP
Mun: 13
Sly: 11
Xarkris: 10

[Map changes: Grung and Snake Statues are now absent, Bilyur is 5 feet south and Mun is 5 feet north]

Daewen shifts her gaze, and the glowing sigil of her Hunter's Mark detaches from the ruined Snake Statue, re-forming on the cracked and battered body of the Gorilla Statue.  She then closes the distance, her rapier flashing as she moves into position.  With a quick thrust, she strikes out twice with her blade, aiming to finish the creature once and for all.

• Rapier Attack #1: 16 Damage: 8 + 2 Hunters Mark force damage = 10 total damage
• IF attack #1 hit- Rapier Vex Attack #2: 26 Damage: 19 + 6 Hunters Mark force damage = 25 total damage
• IF attack #1 missed- Rapier Attack #2: 8 Damage: 10 + 5 Hunters Mark force damage = 15 total damage

OOC: Holy schneikees....please please please tell me that Daewen's first attack hit, because that second attack is downright beautiful!  Check out all those max rolls!

Daewen darts to the right and slams down her rapier into the gargoyle’s face, causing a fracture to develop across its snarling visage. The gorilla statue leers at her, but before it can do anything, she’s thrust her blade back into the crevice and shatters the statue cleanly in two, the stone halves falling apart from each other as the gargoyle crumbles forward. After a moment, the dust settles, and the statues have finally been conquered. 

The silence of the room is a stark contrast to the battle's roar.  Daewen takes a moment, her chest rising and falling with a deep, silent breath.  A small, grim smile touches her lips, and she gives a slow, satisfied nod to her companions.

The glowing mark of her Hunter's Mark flickers, then fades from where the Gorilla Statue once stood.  With her focus no longer on the fight, Daewen flicks her fingers in a swirling pattern, casting Goodberry.  10 ripe, red berries appear.  They are infused with healing magic, glowing softly in her palm.  She quickly gulps down one, healing herself (a measly) 1 HP, and then after surveying her new friends, hands 5 to Xarkris (5 HP healing) and 4 to Mun (4 HP healing).

(OOC: Sorry that is such weak healing, but it's all I've got)
