(shifting this to the OOC thread rather than IC to better facilitate questions and discussion.)
I'm having some technical issues that make it hard to update the map at the moment. So to finish up this encounter let's switch to a more theatre of the mind mode. Forget the limits of the grid and action economy for the moment and picture the scene, and what your character does to help win the day over the next few hectic minutes.
Choose a proficiency, ability or spell; describe how you employ it in the situation; and make an appropriate roll. If you're swinging into the fray, it might just be an attack roll. If you're using an spell in an ingenious way, it might be an Arcana check. Maybe you lead the goblins on a merry chase with a Performance, Stealth or Deception check. If you're using a racial or class feature, pitch me what you think is an appropriate ability score/proficiency to test. If you burn a resource (e.g. a spell slot or a limited use ability) I'll give you a bonus or advantage, depending on what you use and how you use it.
The base DC is 10, and for every 5 you beat that by you'll get an additional good consequence or avoid a bad consequence when we wrap up the scene.
