Bastion Cells are an epic-tier drop that come from one place: the Bastion. If you need Bastion Cells, you need to destroy a Bastion; they don’t appear in containers or general world loot.
Bastion quick facts (what you’re up against)
| Attribute | Detail |
|---|---|
| Threat level | Critical |
| Armor | Heavily plated; front plating is effectively resistant to standard fire |
| Primary attack | Heavy minigun fire; bursts are preceded by a loud screech |
| Burst behavior | Fires for about 3 seconds at the last known position of a target |
| Mobility | Slow, with predictable patterns; dangerous in open spaces |
| Estimated health | ~2000 |
| Key weak points | Rear plate/cylinder and joint areas (notably the yellow kneecaps) |
| Typical entourage | Often accompanied by air support |
Solo loadout that works
You don’t need exotic gear to win solo, but you do need tools that bypass armor and let you reposition on demand.
- Explosives that adhere or detonate on target: sticky mines, C4, long-fuse grenades.
- Control and damage-over-time: stun mines and incendiary grenades to create windows and chip through weak points.
- Heavy ammunition: anything that hits hard in short bursts to punish weak points when they’re exposed.
How to solo a Bastion reliably
- Set the arena: pick terrain with hard cover at two angles (L-shaped cover is ideal). Avoid wide-open sightlines.
- Bait the burst: peek to draw aggro. When you hear the screech, break line of sight and move laterally; the 3‑second minigun burst will track your last exposed position, not your new one.
- Rotate to the rear: use the burst window to flank behind the Bastion. Stay near cover in case air support arrives.
- Target weak points only: plant or throw explosives at the rear cylinder or the joint areas (yellow kneecaps). Follow with focused gunfire on the same spots.
- Chain control: if it turns to face you mid-rotation, drop a stun mine to freeze the turn, then finish the weak-point burst.
- Reset and repeat: as it reorients, get back behind cover, trigger another screech, and run the same flank. Two to four clean cycles typically finish the kill depending on aim and gear.
Hitbox specifics: where to aim and what to ignore
- Don’t waste shots on the front plating. It soaks damage and delays your rotation window.
- Kneecaps: the yellow knee joints are consistent damage multipliers. Hit them as the Bastion starts a turn or when it’s staggered by a stun.
- Rear cylinder/plate: explosives here do the most work per item. Plant a sticky or C4 on the rear, then immediately follow with concentrated fire.
If a weak point is temporarily obstructed, reposition rather than forcing damage through armor. The fight is about timing your flanks, not face-tanking.
Looting the debris and Bastion Cell drops
When the Bastion goes down, it leaves multiple debris piles. Check both the main wreckage and smaller scattered parts. You can expect a mix of ARC components and ammunition; Bastion Cells are part of that loot pool and only come from Bastions.
- Main debris: ARC materials (alloy, power cells, motion cores, circuitry), mechanical components, medium gun parts, medium ammo, and Bastion Cells.
- Small debris: ARC materials and mechanical components, with a chance for Bastion Cells as well.
Don’t rush extraction. Fully clear the site, then loot methodically; it’s easy to miss smaller debris piles, especially in cluttered areas.
Troubleshooting common solo mistakes
- Trading with the front: if you’re taking chip damage behind cover, you’re peeking too long. Shorten peeks to just trigger the screech, then move.
- Explosives whiffing: throw or plant during the 3‑second burst while you’re not being tracked, or right after a stun triggers.
- Getting flanked by adds: anchor your route around hard cover that also breaks line of sight from air lanes. If adds stack up, kite them through your mines between Bastion cycles.
Soloing a Bastion is less about raw DPS and more about rhythm. Force the screech, dodge the burst, flank to the rear, and punish the joints and cylinder. Do that cleanly, and Bastion Cells become a predictable farm rather than a lucky find.
