Scavengers in the Munitions Trade have learned to create and alter their ranged ammunition to suit any situation. These alterations vary from things like extra damage in a variety of types, to curving arrows and piercing bolts. Given their propensity to long range combat, they prefer to do their setup from afar too. These scavengers have learnt to attach their Belt Items to their projectiles to carry them where they need to go, be that a past a well defended choke point, up onto unreachable roofs and balconies, or straight into the face of an enemy.

Some scavengers throughout the D&D multiverse have come into contact with firearms, and have started tampering with their ammunition to, crafting propellant and projectiles that come with a similar range of unique effects.

Munitions Package

As you choose this trade at 3rd level you gain the ability to attach your items to the ranged attacks you make. As part of any ranged attack action you make with a bow or crossbow, you can attach a Belt Item to that attack. If the attack hits, the attached item is treated as if it were thrown at the target, and then immediately takes damage equal to the damage dealt by the attack. If the attack misses, the item drops to the floor where the projectile landed.

You can also use this feature to fix Belt Items like a Razor Wire to an object that is not next to you. If you do, the range of the attack is limited to the length of that Belt Item (if any 15ft in the Razor Wire example.

Ammunition Tampering

Also starting at 3rd level, you gain the ability to add additional effects and damage types to your ammunition. As part of your Specialised Crafting, you can also craft the following items. These pieces of ammunition are considered belt items, and will take up slots on your item belt. As part of a ranged attack, you can choose to use any appropriate ammunition equipped to your Item Belt, instead of the ammunition you would regularly use.

Improved Ranged Attacks

At 6th level you gain the following benefits to your ranged combat.

• Aim: You can now focus your Aim before you make a ranged attack. As an action you may concentrate on a target within range to prepare an attack on it. The next attack you make against that target is made with advantage, after which the effect ends. If you take damage before you make the attack, you must succeed a concentration saving throw or lose this effect. You also lose this effect if you take any actions or reaction that require you to look away from or lose concentration on the target, or if the target moves out of sight.
  


• You can use your Aim actions instead of the last attack you would make as part of an Extra Attack, provided the previous attack was made with the weapon you're choosing to aim.
  

Optional Rule: Firearm Engineering

Also at 6th level, the secrets of gunpowder weapons have been discovered in various corners of the D&D multiverse. If your Dungeon Master chooses to include firearms into this campaign, and your scavenger has been exposed to the operation of such weapons, your scavenger is proficient with them.

Additionally, your scavenger's tinkering with these weapons will give them access to extra crafting options for their Ammunition Tampering

Focussed Aim

At 11th level, your practice with ranged weapons has led to you now being ably to mantain your aim between shots. Your aim benefits no longer end when you make an attack against the target.

Ammunition Bundle

At 17th level, you have started creating bundles of items that you can fire off in quick succession. When you make a ranged attack using modified ammunition, you may have any following ranged attacks made with the same weapon that turn also gain its effects, provided they don't use different modified ammunition. If you have used multiple types of modified ammunition this turn, you must choose one to gain the effects of when you make a ranged attack.

Additionally, when you make a ranged attack with which you are using the Munitions Package feature, you can attach two items instead of one to the attack.

Spot Weaknesses

At 20th level, you have learned to immediately spot any breaks or flaws in the defences of your enemies. The roll required to score a critical hit using a ranged weapon is reduced by 2. When you score a critical hit with a ranged weapon attack, you can roll one of the weapon's damage dice two additional times and add it to the extra damage of the critical hit.
