Relic
Heavy Device
Epic · Updated for patch 1.0.479
Quick answer
PICK IT WHEN
Take it when your current route already produces the reload, luck, boss signals. The value comes from repeating that event, not from the item name or rarity alone.
WATCH OUT
If none of its triggers are happening yet, keep the slot open for a pick that strengthens the engine already on screen.
Editorial read: what this entry is trying to do
Heavy Device is not a universal upgrade. Its recorded identity is reload, luck, boss, and that combination tells you what kind of problem the entry is meant to solve. Start with the current effect, then check whether your run is already producing the event that gives the entry value.
This page treats the current planner record as a decision aid, not as a promise of a fixed ranking. The entry is listed as cross-checked; the effect record currently reads: “• While shooting: 30% Adaptive Chance to reload 1 bullet and increase the damage dealt by your next shot by 1100%.” That wording matters because a rarity label can stay the same while the route around it changes after a patch. The practical question is whether Heavy Deviceimproves the run you have, at the moment you can actually take it.
What the recorded effect means in a run
A relic is a slot decision. It can be powerful and still be wrong when its trigger is not part of the current route or when another slot fixes a more immediate failure.
reload entries change the amount of time the weapon is actually doing work, not just the number printed on one shot luck entries increase the quality or frequency of uncertain outcomes, but they should not replace a route that already has a working base loop the boss tag points toward durable single targets, where uptime and a clear finishing window matter more than one impressive room clear
The current connections point to durable targets and boss windows. It is also connected to the current Hunter routes do not assign this entry to one named Hunter. Those connections are clues, not automatic instructions: a skill can be listed for a Hunter and still be the wrong answer when that run has a different immediate bottleneck. Compare the entry with the other offers on screen before spending the slot.
Early, middle, and late run decisions
Early run: prove the trigger
Early in a run, take Heavy Device only when you can say what it will do in the next few rooms. Take it when your current route already produces the reload, luck, boss signals. The value comes from repeating that event, not from the item name or rarity alone. If the entry needs a second item, a particular element, or a later checkpoint, mark that dependency and keep a simple fallback in mind. An early pick is valuable when it starts a route or removes a failure that is already happening; it is fragile when it asks the run to become something entirely different.
Middle run: check whether the route paid back
In the middle of the run, stop judging Heavy Device by the promise of its text. Look for the event it was supposed to improve: more useful shots, more controlled rooms, a cleaner boss window, or a safer route through the next checkpoint. If that event is not showing up, the correct move can be to keep the item as a placeholder while changing a support slot, or to pivot before the run spends another choice on the same idea.
Late run: protect the win condition
Late in the run, Heavy Device should have a job that can be named in one sentence. Keep it if it contributes to durable targets and boss windows and the effect is still active in the actual loadout. Replace or ignore it when the route has already solved that problem and a missing survival, reload, or target-coverage answer is now more likely to end the run.
Boss, crowd, and fallback use
For bosses, ask whether the entry improves sustained access to the target or only creates a brief high roll. For crowds, ask whether it reduces the number of dangerous enemies that remain after one action. Heavy Device is recorded toward boss pressure; keep a separate room-clear answer if the weapon or skill cannot cover packs.
If Heavy Device does not appear, use a replacement that preserves the same job rather than chasing the exact name. Related entries include Desperate Counterattack, Divine Justice, Siegebreaker, The Magician (Reversed). A lower-ceiling option that keeps the element, trigger, or survival plan intact is usually a better fallback than an unrelated rare drop. If none of its triggers are happening yet, keep the slot open for a pick that strengthens the engine already on screen.
How to test this pick without inventing DPS
- Write down the current Hunter, weapon, active tags, and the reason the run is considering Heavy Device. Do not change several slots at once; otherwise the result cannot tell you what helped.
- Open the Planner with Heavy Device selected and read the synergy explanation. Confirm that the entry is connected to a real trigger, not only to a shared word in the tag list.
- Test one crowded room and one durable target when the route reaches them. Record uptime, missed triggers, reload gaps, and the moment the run becomes safer or more fragile. A single run is an observation, not a universal damage measurement.
- Reopen this page after the next patch and compare the current effect with the recorded one. If the tooltip changes, downgrade the advice until the interaction has been checked again.
Limitations and the next decision
The planner does not claim a measured DPS ranking for Heavy Device. It explains route fit from the current effect, tags, element, Hunter links, and evidence label. That is deliberately narrower than saying the item is always best. The useful output is a reasoned next choice that you can verify in the run.
If this entry fits, load it into the Planner and compare the next skill, relic, and Tarot choice. If it does not fit, return to the item library, filter by the missing trigger, and choose a replacement that fixes the failure you can actually see. That loop is more reliable than copying a static tier list without checking the run state.
