Eclipse Chain-Killer Build: What Does It Mean?

An Eclipse Chain-Killer build in The Division 2 is a hybrid idea that combines the Eclipse Protocol gear set, which spreads status effects when you kill enemies, with the Chainkiller named chest, whose Perfect Headhunter talent turns headshot kills into a big damage bonus on the next hit. It is not an official build name or a standard community meta build. It describes a way to make every kill pay off twice: once by spreading a status effect, and once by loading a damage bonus.

How It Works

A common mistake is to call Chain-Killer a weapon talent. It is not. Chainkiller is a High-End body armor from Walker, Harris & Co., and its talent sits in the chest slot. The two halves of the build work like this:

• Eclipse Protocol (gear set). 2 pieces give +15% Status Effects. 3 pieces add +15% Skill Haste and +30% Hazard Protection. 4 pieces unlock Indirect Transmission: your status effects spread on kill to all enemies within 10 meters and refresh 50% of their duration. The set backpack, Symptom Aggravator, amplifies all your damage against status-affected targets by 30%. The set chest talent, Proliferation, extends the spread to 15 meters and the refresh to 75%.
• Chainkiller (named chest). After a headshot kill, your next weapon hit within 30 seconds deals an extra 150% of that killing blow's damage, up to a cap based on your weapon damage and headshot damage.

Since Chainkiller uses the chest slot, you cannot also wear the Eclipse chest. A typical layout is Eclipse Protocol on mask, gloves, holster and kneepads (or backpack), with Chainkiller on the chest. You keep Indirect Transmission and can keep Symptom Aggravator if the Eclipse backpack is one of your pieces, but you give up Proliferation.

The Trade-Off

Eclipse Protocol pieces come with a Skill Tier core attribute, so the set naturally points toward skill-based play: the Firestarter chem launcher for burns and other skills that apply status effects. Chainkiller has a Weapon Damage core and rewards precise weapon headshots. Mixing them means your gear pulls in two directions, so neither half reaches the numbers of a pure status build or a pure headshot build. The combination makes most sense when you want crowd control and status spreading in groups of enemies while still having a strong follow-up shot on priority targets.

Tips

1. Apply a status first. Indirect Transmission only spreads effects that are already on the target, so tag a group with a burn, bleed or similar effect before you go for the kill.
2. Kill with a headshot. A headshot kill on a status-affected enemy both spreads the effect to nearby enemies and loads the Perfect Headhunter bonus.
3. Keep the Eclipse backpack if you can. The 30% damage amplification against status-affected targets also boosts your empowered follow-up shot.
4. Do not expect a meta build. If you want top damage, a pure Hotshot-plus-Chainkiller marksman build or a full Eclipse status build will usually be more consistent.
5. Check current values. Gear set and talent numbers can change with title updates; see the in-game tooltips or the official The Division 2 site.

FAQ

Is Chain-Killer a weapon talent?

No. Chainkiller is a named chest piece. Its talent, Perfect Headhunter, is an upgraded version of the Headhunter chest talent.

Can I use the full Eclipse Protocol set with Chainkiller?

You can wear up to five Eclipse pieces, but not the Eclipse chest, so the Proliferation chest talent is not available in this setup. The 4-piece Indirect Transmission talent still works.

Is this a good build for beginners?

It is more of an experiment than a guide build. New players usually get better results by committing to one plan: either status effects with Eclipse Protocol or headshots with Chainkiller.
