The 高温射线枪 is a 困难模式, post-石巨人 魔法武器 that auto-fires beams which pierce unlimited enemies and emit bright light. The Heat Ray's beam instantaneously covers its entire range with a solid beam, similar to the 暗影束法杖 — but unlike the Staff, the Heat Ray's laser does not bounce off walls, nor does it lose power as it pierces 敌怪. The Heat Ray has a 12.5% chance to be dropped by 石巨人.
Its best 修饰语 is 神话.
- When wielding the Heat Ray, two fuel tanks will appear on the player's back, overriding the display of 翅膀 when not in flight. However, the display of the hoverboard overrides the tanks.
- It is very effective against 蠕虫-type enemies.
- This weapon and its tooltip are references to H.G Wells' The War of the Worlds, in which Martians fire Heat-Rays, and exultantly cry "Aloo!" or "Oolaa" in the later stage adaptions while waging war in their giant death machines (The tooltip may be an allusion to one line in particular from the musical stage adaptation; wherein the track Thunderchild contains the lyric "Flashing heat rays pierced the deck").
- Even when the player is out of 魔力, the tanks on the back of the Heat Ray appear to still be full of liquid.
