Guide:Sharpshooter

This will be a guide for a build that focuses on dealing Physical damage from a distance.

Core components for this build include:

• Any kind of Hand Crossbows in each hand
• Sharpshooter feat

Sharpshooter provides additional damage for a penalty to accuracy. Attacking from the distance helps to mitigate the accuracy penalty (high ground, hiding) while Hand Crossbows allow to use bonus action to make attacks. Which the bonus damage from Sharpshooter this additional attack more than compensates the fact that Hand Crossbows have less basic damage compared to the Heavy Crossbows.

Having minimalistic core this build allows many approaches from the class perspective. The most notable options are:

• Battle Master fighter
• Hunter ranger
• Gloom Stalker ranger + Assassin rogue
•  Bard and Thief rogue should also be viable choices (that I have not tested yet)

t.b.c.

Other class options

Beast Master: overall a viable alternative for the  Ranger approach. This subclass does not bring improvements to the range combat hence putting the option into "Other" section. Still beasts are strong and overall Beast Master version will bring both firepower as well as survivability and flexibility to the party.

Champion: an alternative option for the  Fighter approach. Main benefit of this version is an improved critical (equivalent to about 5% overall damage increase). For a ranged build a Champion is more interesting than for a melee one - there are a lot of ways to guarantee crits for melee strikers in bg3. Still Battle Master Manoeuvers provide a comparable damage increase together with a ton of utility and flexibility.
Do note that Champion subclass makes more sense for this build if you try to minimise amount of long & short rests.

 Bard: is a full caster in addition to getting 2 attacks (as a ranger or a fighter). Bardic inspiration brings damage increase comparable to a Battle Master or a Hunter. The main upside of the  Bard approach - ability to utilise Concentration way better. Main downside - bardic inspirations take a Bonus action to be used, which will make this version of a build doing less damage comparing to some fighter and ranger options.
While having an access to the awesome Bard's spell list is great, with this build you are still going to use majority of your actions on attacking with the ranged weapon.
