Fjorgin is initially caught in the tendrils, but with some effort he pulls himself free (have a bonus action and movement if you want to do anything else this turn)

Fjorgin moves around to the other side of the beast.

Ekmong’s STR saving throw: 14.

With disgust clearly showing in his facial expression, Ekmong will tap his clothes as to clean them from being slightly soiled by the tendrils. He will then hurl a Fire Bolt at the Ape Monster responsible for the sartorial affront.

-> Fire Bolt vs Ape Monster#2: Attack: 17 Damage: 8 fire.

Ekmong is not moving, so he can be within touching distance from the silver container.

Strength Save: 5

Fjorgin steps forward, now free of the grasping tendrils to engage the ape beast.

Ekmong hurls a mote of flame overhead as it smacks into the ape monster. It seems lightly startled, but fire does not seem too effective on this fiend. (Ape Monster #2: 44 damage.)

Ragmin, seeing that the other monster has managed to reach their back row, conjures forth a blade of Pelor that glistens with a white light. It floats near the monster and swings at it, as Ragmin attempts to smite it with divine flame.
Spiritual Weapon vs. Ape Monster #1: 8 vs. AC. Hit: 11 force damage.
Sacred Flame vs. Ape Monster #1: 19 vs. DC 14 Dexterity Saving throw, taking 3 radiant damage on a failure.

The ape monster manages to dance out of the way of the flames with its agility, but is struck by Pelor's blade. (Ape Monster #1: 14 damage.)

INITIATIVE TRACKER

Thea keeps moving to the right for 15 ft before she focusses her psychic powers to drive a spike into the second apes mind with all force remaining, hopefully finishing it soon enough.

Mind Thrust targeting Ape #2, INT save 15 - DMG: 5

Thea attempts to rend the mind of the ape monster.

Ape #2 Intelligence Saving Throw: 0 

The ape's mind is struck by Thea's psionic abilities, causing it to attempt to shake off the interference. (Ape Monster #2: 44 damage.)

Liavyre, now in combat with the other ape, draws a shortsword with the hand she uses to loose arrows and attempts to slice at it.
Shortsword vs. Ape #1: 15 vs. AC. Hit: 8 piercing damage.

Liavyre's blade is knocked away by the ape monster, causing it no harm.

Ape Monster #2, now with Fjorgin facing it down, looms over him, swinging both of its fists at the paladin before bringing its maw to bite at the crown of his head.
Fist vs. Fjorgin: 10 vs. AC. Hit: 14 bludgeoning damage.
Fist vs. Fjorgin: 21 vs. AC. Hit: 13 bludgeoning damage.
Bite vs. Fjorgin: 13 vs. AC. Hit: 10 piercing damage.

Fjorgin deflects the blows as best he can, but the ape monster gets a nasty punch into his chest. (Fjorgin: 10/36 HP)

Pip, attempting to help rescue Liavyre, draws his shortsword and plunges it at the ape monster's back.
Shortsword vs. Ape Monster #1: 11 vs. AC. Hit: 14 piercing damage.

Pip's sword finds its mark, causing some black ichor to ooze from the back of the ape monster. (Ape Monster #1: 25 damage.)

Ape Monster #1, annoyed by the two skirmishers it has beside it, attempts to strike at both of them before attempting to eat the halfling.
Fist vs. Liavyre: 24 vs. AC. Hit: 10 bludgeoning damage.
Fist vs. Pip: 8 vs. AC. Hit: 11 bludgeoning damage.
Bite vs. Pip: 10 vs. AC. Hit: 10 piercing damage.

The ape monster grabs the small halfling, then bites a huge wound into his head. There is a nasty crunching noise as he lets go. Pip falls unconscious, his skull half-crushed. (Pip: 0 HP. Dying)

INITIATIVE TRACKER

 Edit: the ape monster has disadvantage on attacks vs. Fjorgin. Rerolling those attacks.

12
11
10

(Still one hit)

Fjorgin slashes at the monster with the blade of Pelor's light. 

Attack: 22 Damage: 10

(Want to chuck any smites on that thing?)

Noticing that his fire magic is of little effect, Ekmong pulls his crossbow, light from his back and lets loose a bolt.

-> Crossbow, light (ranged weapon attack) vs ape Monster#1: Attack: 21 Damage: 4 piercing.

Fjorgin slashes into the ape monster, causing a nasty gash to open up along its chest. It is critically injured, almost ready to collapse. (Ape Monster #2: 54 damage.)

Eckmong retrieves his crossbow, light and gets a neat shot into the back of the other ape. (Ape Monster #1: 29 damage.)

Ragmin, short on spells, heads over to where Pip is lying on the floor, and casts Spare the Dying to prevent his death. (Pip: 0 HP. Stabilised. Will awaken in 1 hours.)

INITIATIVE TRACKER

Seeing Pip fall to the ground makes something click within Thea, its like triggering a switch. A sudden stream of emotions rushes into her mind, accompanied by biets and pieces of memories she had partly suppressed, partly forgotten. She suddenly stands still, her fists clenched and compressing her lips, while she tries to retain control of herself and the energies the sudden burst of feelings has provoked. Theas eyes lock on the ape that brought down her halfling companion, she then makes a weird tristing gesture with her index and middle finger.

In his head, however, the Ape (#1) might suddenly hear a female voice, one that is furious but sounds close to collapsing.

 Casting Ego Whip (3 Psi Points) targetting Ape #1: INT Save 15  DMG: 18 (halfed if succesfull, can only dodge, disengage or hide on a fail)

Ape #1's Intelligence Saving Throw: 17

As Thea contacts into its mind, attempting to collapse its ferocity, she hears a voice penetrate back into her own mind. (Ape Monster #1: 38 damage)

DO NOT INTERFERE WITH OUR MEAL, HUMAN!

Liavyre, dropping her bow, pulls a second shortsword in an attempt to take the head off of the ape monster.
Shortsword vs. Ape Monster #1: 15 vs. AC. Hit: 10 piercing damage.
Shortsword vs. Ape Monster #1: 20 vs. AC. Hit: 3 piercing damage.

The twin blades pierce into the neck of the ape monster, causing it to howl in pain as more bloody ichor drip. (Ape Monster #1: 51 damage.)

The Ape Monsters, on the verge of defeat, seem to have communicated in some way. They both let out another cry as they suddenly disappear again, turning invisible as the sound of them retreating can be heard rushing away from the party.

(You may drop out of initiative if you wish. However, if you want to attempt to chase them, then we'll stay in order.)

INITIATIVE TRACKER

Fjorgin runs after them and wildly throws a javelin at where the second monster ran. "Don't let them get away!"

Attack: 26 Damage: 7
Disadvantage: 25

Still quite shaken up, Thea doesnt remember people normally speak out loud.

To Fjorgin:

 (Are the creatures still in range for Thea to attack?)

Fjorgin hurls a javelin, it soars forward and manages to strike at where the invisible beast is fleeing. (Ape Monster #1: 61 damage.)
Ape #1's Concentration Check (DC 10): 21

The javelin hits the monster, but it remains invisible.

(Thea, check which ability you want to use and see whether it requires you to target a creature you can see or not...)

Happy with his successful shot, Ekmong will load another bolt and let it fly. He'd aim at the one he had just hit.

-> Crossbow, light (ranged weapon attack with disadvantage) vs ape Monster#1: Attack: 10 Damage: 7 piercing.

"Where are you?! Running away?" he asks defiantly.

Ekmong's crossbow bolt seems to miss his target. It seems like the ape monster is not quite where he expected.

Ragmin, seeing that they have run away while invisible, uses his last remaining spell in order to attempt to bring them into the light.
Faerie Fire vs. Ape #1 (DC 14 DEX): 11
Faerie Fire vs. Ape #2 (DC 14 DEX): 13

The two outlines of the ape monsters are illuminated by tiny globes of golden light. Pelor has lit the way (they no longer benefit from being invisible, so are targetable by spells. They also grant advantage to attack rolls.)

INITIATIVE TRACKER

(I was just rechecking the damage so far to know what to do, i think Ape #1 is missing the javelin atm, isnt it? It would be at 58 dmg tho, and not at 61 i believe. Just a little confused)

Seeing the fiends light up again, Thea tries to excruciate the mind of the Ape that has no javelin sticking out of its back.

Casting Psionich Blast (2 Psi Points) against Ape #2 - DMG: 5

Thea brings her psionic disciplines forward to wrack the mind of the ape monster. It staggers, nearly collapsing, but barely keeps going. (Ape #2: 66 damage.)

Liavyre aims her bow at the ape monster, sending an arrow straight at the beast.
Longbow vs. Ape #2: 26 vs. AC. Hit: 6 piercing damage.

Between the two ladies, the ape monster becomes visible, and collapses, defeated. (Ape #2: defeated. 78 damage.)
She then targets the other beast with a second Hunter's Mark in order to keep a track on it while they attempt to hunt it down, chasing after it.

Ape #2 is now dead.

Pip continues to lie peacefully.

Ape #1 continues to rush away at a decent speed, faster than the average man can run. (If people are running after it, ranged effects should still be able to follow it. It is 120 feet away from where it was fighting right now, so assuming people move about 30 feet towards it, they'd be 90 feet away from where it is now)
