As a roamer of the no man's land of undead and monstrosities, you've learned the lay of the ruined terrain.

Prolonged Exposure

Having been among the dead and decay has increased your resilience against necrotic energies.

Trick Arrows

At lvl 3, you've learned to use and engineer specially tipped arrows from the scrap and rubble you've collected from patrols.

Net Arrow

An arrow tipped with an end that deploys a net to restrain the target.

Oil Slick Arrow

You shoot a specially tipped arrow which on impact explodes with slick oil in an area. For the duration, these plants turn the ground in the area into difficult terrain.

A creature in the area when you cast the spell must succeed on a Dexterity saving throw or end up prone. A creature surrounded by slippery oil and when moving through it must make another dexterity saving throw.

Smoke Bomb Arrow

An arrow that is tipped with an end similar to a small glass vial that, upon contact, creates a decent sized smoke cloud.

Sonic Arrow

An arrow that is tipped with a sonic frequency emitting end that is very distressing and can also provide sight to 5 ft around where it lands.

Taser Arrow

Arrow tipped with electricity-conductive end that initiates upon contact.

Averted Gaze

The undead have become so used to you and vice versa that they no longer pay as much mind to you as you blend in to your surroundings have been there for so long. In this, you have the ability to cast blur and undead have a -1 in perception on you as well.

Specialization

As later in your journey and survival, you've found a specific fighting style that you tend to lean more towards.

Long Range Marksman

You tend to lean more towards having long sightlines and more space between your foes and yourself. With this, if attacking at your longer range, you gain advantage. However, with this, attacking with your main ranged sniper-type weapon at your shorter range you gain disadvantage.

Up Close and Personal

You've developed a fighting style that allows you to be more effective up close rather than longer sightlines, thus becoming a closer ranged fighter. You gain advantage when in your shorter range, however the further you are, the less effective you become so attacking at your long range opposes disadvantage on our attacks as this is not your strong suit.

Urban Adept

From your time and experience in the ruined cities, you have learned of the best vantage points for sniping and protection. When you are hiding and you take a shot, you gain a +2 to attack rolls and any cover increases by 1 tier. (1\2 to 3\4; 3\4 to full) You also know how to move well around the rubble you inhabit.
