An Act of Hubris or Guile

The necklace slips off a little too easily as the necklace begins coiling itself around Duncan's arm like a parasite. Oriyas gasp for air and passes out due to his severe injures and mangled left arm.

The birds begins swooping nearer and nearer to Duncan.

Kasbis takes the necklace quickly from Duncan with his mage hand, holding it out 30 feet from himself, up in the air.

Duncan will drop the shield now, and try to yank it off with his other hand to throw on the ground if possible.

The necklace refuses to let go. Its grasp is getting stronger and stronger. Duncan begins feeling the presence of another mind intruding onto his own. The intruder is so oppressive as it slowly bends Duncan to its will.

Duncan make a WIs Save

With the failed save Duncan loses control of his arm. It actively fights your other hands attempt to dislodge the necklace.

What do you do?

He's still yanking at it with his other arm

athletics: 16

The necklace looses a bit, but not enough to dislodge it.

What do the other do?

Kasbis uses his mage hand to pick Duncan’s pocket / arm, pulling the necklace off and pulling it 30 feet away from him.  He moves with haste as Duncan has loosened the necklace.  

((Let me know what check you want, sleight of hand?))

Yes please roll sleight of hand

Kasbis sleight of hand : 21 

With the mage hand the Necklace is uncoiled from Duncan's arm. It thrashes around trying to find a host.

Duncan quickly picks up his weapons, putting them on his back, and pulls out his trusty glaive to swing at the birds flying around him to shoo them away.

Kasbis pauses for a second, as the thing squirms in his mage hand, assessing Ori and looking at Duncan and Aisha.  He wishes to see if the Druid is still alive, responsive after being cursed in such a manner.  “What should I do with it?  Fling it, then shatter it, drop it off a tall cliff, bury it, what?”

Running to check on Duncan and do what she can in the situation Aisha yells, "Destroy that thing it's no good."

10 of the 20 blighted birds set their sites on the necklace. They begin dive bombing the mage hand to get the necklace. The other 10 birds scatter into the forest.

Oriyas is bleeding out.

Kasbis replies to Aisha quickly, “Stabilize Oriyas.  I suspect he was being controlled, acting against his will by this foul thing.  Hurry!”  Right after that, as he sees the birds flying around the necklace being held out 30 feet away by the mage hand, Kasbis casts shatter to envelop a 10 foot radius sphere centered on the necklace, hoping to get it to explode and take out as many of the birds with it as he can.  

Shatter : 13 thunder damage, with a DC 14 con saving throw to take half of that damage, with inorganic material such as stone, crystal or metal having disadvantage on the saving throw.  He tries to destroy the necklace and the birds with it.

Birds Con save

14

Aisha runs up to Oriyas kneeling over him laying her hands on him casting cure wounds for 10 HP.

The necklace breaks into 3 pieces and the birds took some damage, but still live. They swoop down and swallow 2 fragments and leaving the 3rd behind, before scattering into the forest.

Now its just you and Oriyas in the clearing. It takes a moment before the natural sounds of the forest comes back
