The site is lagging pretty bad for me and didn't show my first post. 

(after reading the spell, yes. I assumed it was the attacker that rolls. Since the roll has been made i will let the DM decide as of now the real Eider is being hit and i did ask you to roll, albiet in ignorance, but i still asked.)

Tower-7: (Round 5)

Polly lashes out as Eider slips away, slicing through layers of frost and snow.

Grianne crushes the bird-man and restrains him from flight.

(I don't care at all who rolls for Mirror Image. Whoever rolls first is what I take. In PbP if the attacker doesn't roll it usually I will rather than asking the target to roll it.)

Am I grappled?

Polly is grappled and restrained.

(Do we get a free contest to Shmitty's stealth?)
If so: 16

(Will take my turn after DM's answer)

Dope! 

Perception to find Shmitty: 9

(Not that it matters, but do I still have disadvantage while being on top of the tower? I have sharpshooter as well)

(Yes you do. It would be different if you beat my stealth.)

(When a target you are aware of hides you may contest their check. You still have disadvantage to see him in the dark from the top of the tower.)

Griannaconda Bits down on her coiled victim Attack: 18 Damage: 13 

Eider will cast a second level Magic Missile on Polly and then duck into E3 for cover from Shmitty.
