Buy an Underboss Exotic SMG Boost in The Division 2

Underboss is an Exotic submachine gun built around a marking mechanic that rewards focusing damage on a selected enemy. Hitting a target with the weapon applies your mark, causing Underboss to deal +20% Amplified Damage against that marked enemy.

The mechanic becomes even more powerful when multiple agents use the weapon together. Other Underboss users can place additional marks on the same enemy, increasing the damage bonus for each extra mark beyond your own.

Mark Enemies for +20% Amplified Damage

The core Underboss mechanic starts when you hit an enemy. Your mark is applied to the target, and the weapon then deals +20% Amplified Damage against that marked enemy.

This creates a clear focus-fire playstyle. Instead of spreading damage across multiple enemies, you can mark a priority target and concentrate your attacks where the Amplified Damage bonus provides the most value.

Stack Additional Marks With Other Underboss Users

Underboss has a distinct group interaction: other agents using the same weapon can apply their own marks to your target. Every additional mark beyond your own increases the Amplified Damage bonus by another 5%.

With your own mark, the base bonus is +20%. If another Underboss user adds a second mark, you gain an additional 5% bonus against that enemy. This creates increasing value when multiple players coordinate their attacks against the same target.

Focus Team Damage on Priority Targets

The shared marking mechanic gives Underboss a natural role in coordinated group activities. Multiple weapon owners can select the same dangerous enemy, apply their individual marks, and benefit from increased damage while maintaining focus fire.

This can be particularly useful against bosses and other high-priority PvE enemies that remain alive long enough for the group to take advantage of stacked marks. Underboss rewards coordination rather than treating each player's weapon mechanic in isolation.

Build an Aggressive Loadout Around Underboss

As a submachine gun, Underboss fits naturally into an aggressive weapon-focused playstyle. Supporting gear can be selected around the offensive attributes and combat approach you want to use.

The Exotic marking mechanic then adds another layer to the build. In solo situations, your own mark provides the base +20% Amplified Damage bonus, while coordinated groups with additional Underboss users can increase that bonus further.

Skip Repetitive Underboss Farming

If Underboss is the specific Exotic SMG you want, obtaining it manually can require repeated farming before you reach your target.

An Underboss Boost focuses the process on obtaining the weapon. Once acquired, you can add it to your Exotic collection, create a dedicated SMG build, or coordinate with other Underboss users to take advantage of additional marks against priority enemies.
