Radiation Beam
Emit a radiation beam on hit that deals {[min_laser_damage]}-{[max_laser_damage]} damage and applies 1 stack of radiation (max {[max_radiation_stacks]} stacks). Radiation lasts for {[radiation_length]} seconds and cause enemies to receive {[radiation_pct]} more damage from all sources per stack.

| Tier | A |
Rating
Radiation Beam is an A-tier debuff ball similar to X Ray. It fires a beam on every hit that both deals direct damage and applies radiation stacks. Like X Ray, radiation stacks multiply all incoming damage — each stack makes the target take X% more from every source.
The key difference from X Ray: Radiation Beam's stacks have a time limit (X seconds). X Ray's radiation was permanent; Radiation Beam's requires consistent re-application to maintain. With high-frequency hits, the stacks continuously refresh before expiring, functionally becoming permanent.
This dependency on hit frequency makes Radiation Beam a high-reward debuff for builds that maintain rapid fire, but less reliable than X Ray if hit rate is inconsistent.
When to Pick
- Multi-hit builds that can maintain rapid stack refresh to prevent expiry
- Multi-DOT builds where radiation multiplies every DOT tick
- Complement to other radiation sources (X Ray, Nuke) for earlier max-stack application
- Builds wanting beam damage + debuff in one ball slot
Best Characters
| Character | Synergy | Reason |
|---|---|---|
| Multi-DOT builds | S | Radiation multiplies all DOT ticks; beam applies stacks while DOTs benefit |
| Multi-hit builds | A | High fire rate maintains stacks before expiry, functionally permanentizing radiation |
| General damage builds | A | Radiation on any target multiplies all subsequent hits |
Recommended Passives
| Passive | Synergy |
|---|---|
| Radiation stacks per hit up | Faster stack accumulation |
| Radiation stack cap up | Higher multiplier ceiling |
| Radiation duration extension | Stacks last longer, reducing refresh pressure |
| Beam damage up | More direct damage per beam |
| Fire rate increase | Maintains stacks before expiry more reliably |
TL;DR
Radiation Beam fires a damage-dealing beam on hit and applies radiation stacks that increase all incoming damage per stack. A-tier timed radiation — similar to X Ray but with stack expiry that requires active maintenance. Strongest in high fire-rate builds.
