Sometimes, the people you steal from get a little upset. No worries, you're happy to reimburse them with bullets. You gain the following abilities;
When a creature moves within your ranged weapon's short range for the first time, you can use a reaction to make a ranged attack against it. If you reduce the target to 0 hit points with this attack, you gain a bonus equal to tier to your next ranged weapon attack roll made within 1 minute.
You gain a bonus to your movement speed equal to 15 feet (max 60). In addition, you can use your quick step to evade an attack. When you do so, you reduce the damage taken by the attack by half, and gain resistance to that damage type until the start of your next turn. Doing so cause you to lose the benefits of quick step until you complete a short rest.
At Tier 6, ranged weapon attacks against you are made at disadvantage, and you have advantage on Dexterity saving throws against effects you are able to see.
In addition, you add a bonus to your Dexterity saving throws equal to your tier.
