The Master Archer has dedicated their life to deadly application of ranged weapons.  Their mastery of the bow and arrow is so complete as to take on an almost mystical quality.  They wield the bow and arrow with unmatched deadly precision. 

Deadly Archer

You now Critically Strike with a 19 or 20 when taking the Attack action with a ranged weapon for which you have the Weapon Mastery property.

Relentless Archer

Each time you consecutively hit a target with a ranged attack that you have marked with Hunter's Mark, you deal an additional die of damage of the same type and die as your Hunter's Mark.  This effect stacks a number of times equal to your proficiency bonus.  All stacks are lost if you miss with an attack, make an attack on something other than the creature marked by your Hunter's Mark, fail to take the attack action on your turn, or if you lose concentration on Hunter's Mark.

Once you deal max damage, all stacks are expunged and the target must make a constitution saving throw vs your Spell DC or be stunned until the start of your next turn.  On a successful save the target's speed is halved and it has disadvantage on the next attack it makes before the start of your next turn.  

Unending Volley

When you take the Attack action and use all of your attacks to make a ranged attack and hit with all of them, you may use your bonus action to make an additional ranged attack with the same weapon.

Mystic Archer

Magic Arrow

When you take the Attack action on your turn, you may use one of the attacks to cast a spell that would normally have the range of touch. To do this you must make a ranged attack against the targets AC, if the target is a willing creature, their AC for this attack is 10.  If the spell cast this way would normally require a spell attack, this attack replaces that requirement.

Rain of Arrows.

When you use a ranger spell to damage multiple targets, if one of the targets is marked by your Hunter's Mark, all targets take the bonus damage from Hunter's Mark.
