GM Shot down my Stormborn Air Genasi Sorcerer/Monk soooo.. I guess it will be the EK ranged with Longbow or Crossbow. I haven't decided on the race yet, so it depends.. Probably a Variant Human, since Feats are used in the campaign, so I can get Hex via Magic Initiate (plus cantrips from Warlock).
I'm thinking 3 levels in Rogue to get me to Assassin. This gives me Expertise, Sneak attack, Cunning action and assassinate. So I can attack (with longbow 1d8 +1d6 dmg for sneak attack, +1d6 from Hex and auto crit from Assassin) bonus up to slip back into hiding and expertise to make that roll a good one.
Then comes the 5 levels in Fighter. That gives me access to Archery (+2 to hit), Second Wind, Action Surge, a second feat (Sharpshooter or crossbow expert) an Extra Attack, two more cantrips (wizard), 3 level 1 wizard spell slots, and Weapon Bond.
Now, do I go bow and therefor Sharpshooter OR do I go crossbow and use two hand crossbows??? (using the bonus action for the hand crossbow allows a free attack, but sacrifices the ability to fade into the shadows on a bonus action, so I am leaning towards Sharpshooter and the Long Bow.. and honestly Skulker sounds more useful than Sharpshooter at first.
