The Division 2's new raid Dark Hours introduced a new Exotic weapon, an assault rifle named Eagle Bearer. It mimics a P416 and drops exclusively in the raid but there are a few tricks that might help you get the AR without completing it.
Eagle Bearer drops strictly from Dark Hours bosses and the reward chest that requires a key. The drop rate is low but you are not required to complete the raid in order to get the weapon, which leaves space for farming manoeuvres.
In case you are discouraged from attempting to farm Eagle Bearer by the lack of matchmaking for Dark Hours or the fact that you need to find seven other players with optimised builds in order to attempt the raid, maybe you shouldn't be.
The raid itself doesn't have a time gate and all the bosses have a chance to drop Eagle Bearer. This means you can go in, kill the first two bosses and if they don't drop the Exotic, you can replay them and hope for better luck.
This way you would eliminate the higher challenge that comes with attempting to do Lucy and Buddy as well as the final boss. Furthermore, starting with the doggo duo, the raid time sink grows disproportionately so the optimal usage of your time would actually be to keep killing the first two bosses.
In case you are struggling with Boomer, you could check out our guide to defeating the big bad minigun destroyer. He isn't that much trouble if the entire team knows what to do at any given moment. Oliver "Weasel" Gordon seems to be the easiest boss of the raid and we will have a guide for him soon.
If you do decide to do it the old fashioned way, you will have a higher chance to loot Eagle Bearer due to more drops from bosses themselves and the loot chest that spawns after defeating DDP-52 Razorback. More walkthrough guides will pop up soon but Lucy and Buddy can really be annoying. You have been warned.
