Mages are often paramount tools of the mighty or the wealthy and those types of people tend to make many enemies. Those who are able will often seek the skills of an Archunter. Archunters are mages committed to the art of tracking and capturing a chosen target. Mixing elements of lethal magi and inquisitive hunters, Archunters creep from the nightmares of the creatures that would incur ones wrath.

Hunter's sight

At 2nd level, you have learned to tie yourself to the presence of your magic and to the ambient magic around you.
You gain darkvision up to 60 ft and if you already have darkvision the range is extended up to 60 ft. 

Additionally, when a creature you target is struck with a damaging spell that requires an attack roll, the creature is marked and cannot hide from you while you are within 100 ft of them. This will allow you to detect an invisible or concealed foe that you have hit with a spell.

Archunters wrath

Starting at 2nd level, your lethal capabilities overlap with your skill, your spell damage rolls become especially potent.

When you hit an enemy with a ranged spell attack you may add your proficiency bonus to the damage roll of the attack.

Hunter's dread

The aura of an arcane hunter surrounds you in a dreadful gloom. When you use a spell on a target you may use a bonus action to fill your target with fear.

Your target must make a wisdom saving through or be Frightened of you. The target may repeat the saving throw at the end of their next turn and will last for up to a minute.
Your target must be able to see you in order for you to apply this effect.

You may use this ability once per short rest, but if you kill a hostile creature in combat your use of this ability refreshes.

Arcane screen

Beginning at 10th level, your eyes become shielded from blinding effects that would hide your prey from you.

 You gain blind sense up to the length of your darkvision and are immune to blindness effects that would hinder your vision.

Deadly Exploitation

At 14th level, your predatory casting allows you take advantage on a hindered target with lethal efficiency.

As a reaction you may use a spell attack roll on a target that is afflicted with the following status effects:  knocked prone, stunned, paralyzed, frightened, restrained, or charmed.

When a creature that you can see or sense, within range of a spell attack roll is afflicted with one of theses status effects, you may use your reaction to make said spell attack roll with one spell that has a casting time of one action or bonus action on that target. This attack roll has advantage but ends the effect on that target.
