This Black Desert Online (BDO) Archer Skill Build Guide will teach you all you need to know in order to make the best Archer skill setup.
The Archer is the latest Black Desert class that came out in December, Archers are extremely powerful and in case you are not already playing one you should check them out for sure!
Without further redo, let's get to the skill build and spell opinions.

Pre Awakening (Main) Archer Skill Build

Purging Shot does a good amount of damage but it scales off the Earth Kick damage which means you have to put skill points into both which might not always be optimal. If you have a low amount of skill points and you're still grinding you will want an Archer skill build that does the highest amount of damage with lowest investments. 
Ensnare is really strong because it gives you a critical buff and it can one-shot a pack of monsters with ease. Meteor Dive can be combined with Ensnare for even more damage output.
Covering Fire should always be invested in if you have extra points but it's useful even with just one level because it allows you to animation cancel some skills.
Winged Strike is a skill you most definitely will want to place your points into along with Wrath of Nature and Bolt of Radiance because these skills have a lot of damage and will easily increase your overall monster farming clear speed.
Arrow Explosion has a decent amount of range and it can kill a pack of mobs but remember that it will not hit a pack that is right in front of you so you need to strategize your skill shots.

Awakening Archer Skill Build

Radiant Explosion will offer you a decent amount of damage and AoE at the cost of range.
Full Bloom - place at least one point into it and then max it out if you have extra points.
Spear of Slyvia spins and pulls mobs which can be useful if you require some extra crowd control, whilst it can damage monster it does lack some DPS to actually one-shot. A good Archer skill combo for PvP you can use is Spear of Slyvia and Ensnare. 
Luthraghon's Call is a must, does a decent amount of damage and provides you with a knockback which is really useful in both PvE and PvP situations because Archer is really strong when he utilizes his knockbacks well.
Uproot - okay skill which provides good movement, nothing special about it but one point in it can prove itself useful especially in combos with Luthraghon's Call.
