An Act of Hubris or Guile

Shadow demon 1 will move to attack Aisha

Attack: 11 Damage: 10

Shadow demon 2 will take the Dash action to reach Kasbis

Round 2 Post when able.

Kasbis feels panicked and frightened by this Other-Ellsia, and he runs to the north, getting away from it (and risking an AoO in doing so).  He turns and fires at the shadow demon that is chasing him, 2 bolts of force energy.  

Eldritch blast 1 :  16 to hit, for 9 points of force damage.  

Eldritch blast 2 : 26 to hit, for 10 points of force damage and 3 points of thunder damage.  

After he is clear from the scary sight of Ellsia, he shakes his head and tries to calm himself from the fear that has gripped him.

Wisdom save : 11

Kasbis is still frightened

 On his turn Duncan will turn to the nearest demon, the one attacking Aisha, and attack it.

Round 2:

Duncan will just continue working on the monster next to him, hoping to take out the smaller foe before moving to focus on the poor possessed miner.

Duncan sees a deadly foreboding mist like creature that attacks Duncan. To your senses it is completely real and you take 5 psychic damage each round. Duncan can use an action and roll investigation check DC 14 to see through the illusion on each subsequent turn.

If attacking the illusion, Duncan strikes just go through the mist like creature.

Aisha calls out to Duncan and Kasbis, "We've got this guys! Stand firm!" Using her action to cast Beacon of Hope.

Ellsia moves to Duncan and attacks with shadow tendrils

Hit - 22 damage - 18 necrotic

When hit your hit point maximum is reduces by 3 (1d6)

Rolled in game log

Shadow demon1 attacks Aisha

Attack: 18 Damage: 14

Shadow demon2 moves to and attacks Kasbis

Attack: 17 Damage: 10

Round 3 Post When able

Shadow demon 1 is hurt , but still going strong.

 3 psychic damage for Duncan if he does not use an action for an investigation Check DC 14

Seeing the shadow demon slash at her and feeling the impact of the hit, Aisha loses concentration on Beacon of Hope. Seeing Duncan being injured and under some kind of influence, "Duncan, you're the protector but you're taking an attack from something that's not there in your efforts to protect." She will then use her Channel Divinity: Preserve Life to give Duncan 25 HP.

With her bonus action Aisha casts Spiritual Weapon at 3rd level to attack Shadow Demon 1.
To Hit: 14
Damage: 7 Force Damage

As the miner demon approaches him, Duncan uses his reaction to swing at it.

Attack: 12 Damage: 7 ((if this hits it would stop the demon in place. Does it have a 10ft range?))

Then, seeing the tendrils come out, decides to focus his attacks on it, regardless of its distance.

Action:
Attack: 11 Damage: 7
Attack: 10 Damage: 13
bonus: 
Attack: 24 Damage: 4

It is a miss so the demon was not stopped.

Kasbis grunts as the shadow demon’s attack hits him, he grits his teeth and growls in anger.  He casts Eldritch blast at the 2nd shadow demon attacking him.  (at disadv since they are melee).

Eldritch blast 1 : (Nat 20 x 2!  Crit!) 27 to hit, for 15 points of force damage, plus 3 points of thunder damage (is that doubled as well?).  

Eldritch blast 2 : 20 to hit, for 13 points of force damage.  

(I don’t think I have ever rolled two 20’s for an attack with disadvantage before!)

(Nice double crit)

Ellsia attacks Duncan again with shadow tentacles

Hit- 23 Damage - 9

Hit point maximum reduced by 1

Shadow 2 continues to attack Aisha

Attack: 8 Damage: 14

Shadow demon 1 shrieks in pain from the crit eldritch blast and attacks Kasbis

Attack: 17 Damage: 10

Round 4 Post when able

1 psychic damage for Duncan. Unless Duncan passes DC 14 investigation check using an action.

Correction from above its shadow demon 2 that shrieks and attacks Kasbis

Round 3 : 

Forgot the wisdom save for Kasbis, at advantage due to the beacon of hope.  

Wisdom save to end being frightened :  22 

Feeling his resolve improve, less frightened of the Other-Ellsia that he can no longer see, Kasbis continues to focus on the Shadow Demon that is attacking him.  Again he shoots out two blasts of force energy at it.  “I can’t take much more!  Die you shadowy beast!”  (Disadv continues due to ranged attack on a melee opponent).  

Eldritch blast 1 : 26 to hit, for 8 points of force damage and 3 points of thunder damage.  

Eldritch blast 2 :  8 to hit (miss).
