I love Emilia
2 things.
1. Technically you have advantage because you're stealthed and not north of them, but the range 150/600 on a long bow means up to 150ft you make a regular attack 151-600 you have disadvantage (Unless you have the sharp shooter feat) which they both cancel out. (I'm not sure where you got the attacking someone before they move you have advantage on comes in. Certain classes have that but I'm not sure if any of them have that at level 3.)
2. Your 2-300 feet away but which direction and who are you attacking? (The map does have numbers/letters if you squint near the people.)
