Get the Underboss Exotic SMG – The Y8S2 Climax Mission Reward That Marks Enemies for Extra Damage
The Underboss is one of the two new Exotic weapons introduced in Year 8 Season 2 "Into the Dark". It's a hard-hitting SMG built around a single, aggressive playstyle: every shot applies a mark to the enemy you hit, and the weapon deals +20% Amplified Damage to marked targets. The Optics slot comes with +15% Critical Hit Chance, making it easy to stack crits while you paint targets. The real power comes from stacking marks. You can transfer marks between enemies, and every extra mark on a single target adds another 5% damage, meaning focused fire on a priority enemy can push your damage output well beyond the base 20% bonus.
KingBoost's team runs the Climax mission on your account until the Underboss drops. We handle the full mission on Master difficulty, securing the guaranteed Exotic SMG for your collection. All other High-End gear, Exotic items and Season Pass XP earned during the farm stay on your account. You get the Underboss and everything else we find along the way.
50,000+ players trust us. That number isn't luck—it's the result of years of consistent delivery, professional boosters and a support team that cares about your experience.

Gangland Hit marks enemies when you shoot them. The Underboss deals +20% Amplified Damage to marked targets. You can transfer the mark between enemies, and multiple marks can stack on the same target, increasing the damage by 5% per extra mark.
You need to complete the season's final Climax mission on Master difficulty. Lower difficulties give you a chance at the drop, but Master is the only guaranteed source. The mission is part of the Y8S2 Manhunt.
No. The Underboss is tied to the Climax mission, not the Season Pass. The Caduceus is the Season Pass Exotic. You do not need to buy the premium pass to get the Underboss, though you do need access to the season's content.
Both. The mark transfers between enemies, so you can paint targets in solo content and burn them down quickly. In group play, the amplified damage applies to all sources, making it a strong support tool for focusing priority targets.

KingBoost has been my go-to for Mythic+ dungeon boosts, and the service has been consistently strong. Scheduling is quick, communication is clear, and runs usually start without the usual wait you get from pug groups.The teams know the current dungeon pool and play clean. Keys get timed when that’s the goal, routes are efficient, and the runs feel organized instead of chaotic. I have used them for single keys, bundles, and gearing, and the results have matched what was ordered: completed dungeons, rating progress, and loot/Vault progress as expected.Pricing is also a big reason I keep coming back. After comparing a few boosting sites, KingBoost has usually been the best value for the same key level and options.If you want Mythic+ done quickly with a competent group and without overpaying, KingBoost is easy to recommend.
Quick and easy run, highly recommend!
Fastest available
Smooth as always!
