Red Text
Who you calling short?!

This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.

When thrown and placed, it explodes and leaves a “moving turret”. It is a Daedalus‑made Legendary grenade that, after impact, rolls while talking for a while and explodes after 5 seconds. It leaves a Bouncing Betty (bouncing turret) on the spot, firing 360° while also scattering homing rockets—a single throw like a deployable turret.

🧩 Red text origin “Who you calling short?!” is a quote from ‘League of Legends’ champion Draven when catching a thrown axe that bounces back (MentalMars/Lootlemon). The fact that Fuse is a grenade with a “bounce” behavior matches Draven’s axe bounce. Because it comes from a secondary summary source, the original source is (unverified) (will add if verified with primary source).

What kind of grenade? (Beginner’s perspective)

• When thrown, flies in a parabolic arc, talks a bit while rolling, then explodes after 5 seconds (not an instant explosion, a placed type)
• Upon explosion, Bouncing Betty (bouncing automatic turret) appears, shoots 360° for 6 seconds (each hit 10% element splash)
• Additionally, Betty fires 5 homing rockets, which track nearby enemies and explode (each 50% element splash)
• Once thrown, continues firing automatically for a while = strong in situations where you want to generate ammo or push

Unique effects (mechanics)

After impact, explodes (100% element splash). On explosion it spawns Bouncing Betty, firing 360° for 6 seconds (each 10%) + 5 homing rockets (each 50%). Betty is treated as an ally, so some effects stack twice.

• In-game: detonates after 4–5 seconds
• Web (Lootlemon): Thrown in an arcing trajectory, briefly talks and bounces before settling, then explodes after 5s for 100% [Element] Splash. On explosion spawns a Bouncing Betty that jumps and shoots 360° for 6s (each hit 10%), and launches 5 homing rockets (each 50%). The Bouncing Betty counts as an ally and its damage benefits from some effects twice.
• Because Betty is treated as an ally, it may synergize with buff builds that benefit allies (detailed double‑stack conditions are (unverified))
• Weakness: because it does not explode instantly, it is unsuitable for close‑range emergency evasion. Its strength lies in placing it to fire.

Drop farming

Build compatibility

Summary

• A deployable Legendary grenade that leaves an automatic turret (Bouncing Betty) after exploding
• 360° shooting + homing rockets allow you to generate ammo even when just throwing it
• Because it is a placed type that does not explode instantly, it is more suited for pushing than emergency evasion
• The red text is a League of Legends Draven reference ((unverified))
• Obtained from Driller Hole (Queen’s Cradle)
