ARC Raiders Seeker Grenades: How Many Kill a Bastion?
In ARC Raiders, plan on about three Seeker Grenades to kill a Bastion if they all connect and detonate effectively. Treat that as a practical estimate, not a guaranteed fixed count: grenade damage can vary with the blast, the Bastion’s remaining health, and whether the grenades reach it rather than getting intercepted or missing.
Why Three Is a Useful Estimate
A Bastion is a heavily armored ARC enemy, so it takes more than one explosive to bring down. Players commonly use roughly three Seeker Grenades as a starting estimate for a full-health Bastion. The key word is “roughly”: a count seen in one encounter does not prove every Bastion has identical health or that every grenade will deal identical damage.
If you are planning a fight, carry enough supplies for the expected three hits plus a margin for a miss or an interrupted attack. If the Bastion is already damaged, fewer grenades may finish it; if one fails to connect properly, you may need another. The number is a field estimate rather than a promise that three throws will always produce a kill.
How Seeker Grenades Work Against a Bastion
A Seeker Grenade is a throwable explosive intended to pursue a target. Against a large ARC enemy, that seeking behavior can make it easier to land damage than with a simple throw that depends entirely on your aim. It does not make a hit automatic, however: the grenade still has to acquire and reach a suitable target, and the enemy’s movement or the surrounding environment can affect the result.
Think of the kill count as a sequence of successful detonations. A grenade that is blocked, drawn to another target, or otherwise fails to damage the Bastion does not count as one of the hits needed to finish it. Likewise, a grenade that arrives while the Bastion has already taken damage is contributing to a different remaining-health total than it would against a fresh target.
- Full-health target: Use about three successful Seeker Grenades as your baseline.
- Partly damaged target: Expect the required number to decrease, depending on how much health remains.
- Missed or ineffective grenade: It may add no useful damage, so the total number thrown can exceed the baseline.
How to Use the Estimate in a Fight
Before committing your explosives, check whether the Bastion is already engaged or damaged. If teammates have been attacking it, you may not need to spend a full set of grenades. If it is fresh and you want to rely on grenades alone, plan around three effective hits and keep a fallback option available.
- Identify the target. Confirm that the ARC enemy is a Bastion, rather than assuming the same grenade count applies to another ARC type.
- Get a clear opportunity. Avoid throwing when obstacles, nearby threats, or a poor angle are likely to prevent the grenade from reaching the Bastion.
- Watch the result. Look for whether the grenade actually detonated on or near the target and whether the Bastion remains active.
- Adjust rather than blindly repeating. If the target has taken damage, continue only as needed; if a grenade failed to connect, do not treat it as a confirmed hit.
This approach is more useful than memorizing a number without considering the encounter. In a coordinated fight, teammates’ damage can change the count substantially. In a chaotic fight, your own grenades may be less reliable, making a spare more valuable than a perfectly precise inventory plan.
What Can Change the Grenade Count?
The most important variable is effective damage, not the number of throws. A direct or otherwise successful detonation contributes to the kill; a grenade that does not reach the Bastion may contribute little or nothing. Its current health also matters: the three-grenade estimate is most relevant when starting against a full-health target, not when finishing an enemy that has already absorbed damage.
Game balance can change as ARC Raiders is updated. If an update adjusts enemy durability, explosive damage, or grenade behavior, older community estimates may no longer match current encounters. For a precise answer in a particular build, observe the result in that version and distinguish confirmed hits from grenades that failed to connect.
There is also an important difference between “grenades needed” and “grenades thrown.” The first describes successful damage needed to defeat the Bastion; the second includes misses, blocked throws, and other failures. When players report different counts, they may be describing different conditions rather than contradicting one another.
Seeker Grenades Compared With Other Approaches
Seeker Grenades are convenient when you want an explosive that can pursue a target, but they are not the only way to fight a Bastion. Weapons and other equipment can contribute damage, and a squad can combine attacks instead of asking one player to spend several grenades. Which approach is best depends on your loadout, available supplies, positioning, and whether the Bastion is already under fire.
Do not assume that the Seeker Grenade estimate transfers to every explosive or weapon. Different items can have different damage, targeting behavior, and practical reliability. A fair comparison needs to account for successful hits, the target’s remaining health, and the resources consumed—not just the number of items used.
- Use Seekers when: you have them available and want a throwable that can pursue a target.
- Combine damage when: teammates or your weapons are already contributing, so grenades can be saved for the remaining health.
- Keep a backup when: a missed throw would leave you without a reliable way to finish the fight.
Common Misconceptions
“Three grenades always kill every Bastion.” Not necessarily. Three is a practical baseline for successful hits, not a guarantee independent of target health, grenade behavior, or game balance.
“If I threw three, I landed three hits.” Throwing and damaging are not the same. Check whether the grenades reached the enemy and detonated effectively before concluding that the usual estimate is wrong.
“The count is the same for every ARC enemy.” Enemy types differ. A Bastion-specific estimate should not be applied to another ARC without reliable evidence that its durability and damage conditions match.
Frequently Asked Questions
How many Seeker Grenades does a full-health Bastion take?
Use about three successful Seeker Grenade hits as a practical estimate. Allow for a spare if a grenade could miss or fail to damage the target.
Can one Seeker Grenade kill a Bastion?
Do not expect one grenade to defeat a full-health Bastion. One may help finish a Bastion that has already taken substantial damage, but the remaining health determines the result.
Do missed Seeker Grenades count toward the three?
No. The estimate is about effective damage. A grenade that does not reach or damage the Bastion should not be counted as a successful hit.
Will teammates reduce how many grenades I need?
Yes. If teammates have already damaged the Bastion, less health remains, so your grenades may finish it sooner. The exact reduction depends on the damage already dealt.
Is the three-grenade count guaranteed after an update?
No. Balance changes can alter damage or enemy durability. Treat three as a useful estimate and verify it against the current game version if exact resource planning matters.
