Working on the post. Just need to clarify one last thing: since they're up 10 feet above the ground, trying to jump down would cause them to take fall damage, right? If so, can Flicker jump down and attack (using Produce Flame) even if they take damage? (Sorry, still newish to 5e, not fully comfortable with combat rules ^^;)

If not, I'll probably just attack using Produce Flame from the window.
