O.S.C.A.R.

O.S.C.A.R. is an Elite-class enemy that serves as the boss of the Winery Guild Strike in BO7 Endgame. Players frequently have questions about its spawn location, whether it still respawns, and why lower-CR players struggle to damage it effectively.

What O.S.C.A.R. is

O.S.C.A.R. is a large mechanized robot. It is the final boss of the Winery Guild Strike and blocks access to the Exotic Fabricator until defeated. UFO drones orbit it and provide a damage immunity shield.

Spawn location and timing

O.S.C.A.R. spawns from the Winery Guild Strike. The Winery is located in Zone III. A Nightmare Zone overlay activates at the location when the Guild Strike triggers at the 45:15 match timer mark.

To trigger the boss fight:

1. Locate the Winery Guild Strike on the tac map when the 45:15 timer triggers
2. Eliminate all enemies during the Guild Strike Activity
3. O.S.C.A.R. spawns as the final stage of the Activity

Caution

O.S.C.A.R. does not respawn after defeat. It originally respawned every 10 minutes, but this was removed in Season 3 Reloaded due to a health bar UI bug. O.S.C.A.R. now spawns once per game.

Recommended Combat Rating

The Winery Guild Strike triggers a Nightmare Zone overlay at the Zone III Winery location. The recommended Combat Rating for Nightmare Zone content is CR 55+. Players significantly below this threshold will deal reduced damage due to the zone’s power scaling.

Community reports indicate that players attempting O.S.C.A.R. below CR 45 will struggle to deal meaningful damage, even with exotic-rarity weapons. At CR 55+ with a fully built exotic weapon, the fight is manageable for a small squad.

Fight mechanics

O.S.C.A.R. has the following core mechanics:

UFO Drone shield: Between 1 and 4 UFO Drones orbit O.S.C.A.R. and provide an immunity shield. The drones must be destroyed before any damage can be dealt to O.S.C.A.R. itself. Drones are low-health and die quickly to sustained fire.

High health pool: O.S.C.A.R. has much more health than standard elite enemies. You need multiple players with exotic-rarity weapons to take it down fast.

Community strategies

Positioning: Try to stay behind O.S.C.A.R. while clearing drones. After all drones are down, focus fire on O.S.C.A.R. from behind for the best damage window.

Priority on drone clearing: Every moment O.S.C.A.R.’s drones are alive is damage prevented. Squad members should assign at least one player to drone clear at all times to maintain consistent damage windows.

Loadout considerations: Sharpshooter is a strong choice here. O.S.C.A.R. has no weak point, but Sharpshooter makes all chest hits count as crits. No need to aim for a specific spot.

Rewards

Defeating O.S.C.A.R. completes the Guild Strike Activity and spawns the Exotic Fabricator for participating players. The Fabricator can be used to upgrade any carried weapon to exotic rarity or to reroll traits on an existing exotic weapon.
