Identify the enemy whose death triggers an explosion
Fusefly is a hostile Dungeons II creature found in The Sift. The Fusefly record identifies ordinary melee behavior while it is alive and an explosion on death.
Separate the living enemy from the death event
A Fusefly presents a sequence with two distinct parts. While alive it behaves as a basic melee enemy, so the immediate interaction is a creature approaching to fight. Once it is killed, the documented explosion becomes the relevant event. A clip that ends at the killing blow may omit the feature that best identifies this mob.
As a practical reading of that sequence, finish observing the death effect before moving your attention completely to the next enemy. This is especially useful when several melee creatures are together and the source of an explosion is unclear. Trace the burst back to the defeated Fusefly rather than assuming a surviving ranged creature fired it.
Compare three different explosion triggers
The Pollinator launches globs that burst after a delay; the source of that event is a projectile. A Scavenger throws tracking souls whose explosions leave soul fire; its effect includes both a flight path and a remaining ground hazard. Fusefly’s trigger is the creature’s own death.
These distinctions help you interpret a busy fight without relying only on the color of a burst. Ask what happened immediately before the explosion: a glob was launched, a soul projectile arrived, or a melee enemy died. The answer points to a different creature and a different part of its behavior.
What the stage images can help you recognize
The additional renders and the “about to blow up” screenshot show that the source includes more than one visible pose or state. Use them to match a changing appearance in footage. Treat the pictured stages as appearance references; the documented trigger for the explosion is death.
The historical record places Fusefly in early Dungeons II key art. For current identification, the action sequence is more useful than that reveal date: melee while living, explosion after death. Follow the mob directory if the creature instead attacks entirely from range or if the effect you are investigating leaves a persistent pool; those cues point toward a different entry.
