Doom

The Doom rune instantly kills any enemy at or below 20 HP, bypassing the need to land the final hit manually. This execution mechanic eliminates the inefficient low-health cleanup phase of combat, where enemies survive at near-zero HP and waste attack time that could be spent on the next target. The only restriction is that Doom does not function against bosses, keeping the instant-kill mechanic balanced for standard mob content.

Doom starts at the Small size and follows the universal upgrade recipe: five Doom runes of the current tier plus five Runalit crystals at the Rune Crafting Station advance it to the next size. Higher rune sizes may raise the HP threshold at which the execution triggers, making Doom more reliable and effective at larger sizes. Prioritizing Doom upgrades alongside weapon upgrades maximizes the synergy between stronger hits and wider execution windows.

Doom is most powerful in high-density farming zones where the player cycles through many enemies quickly, as the instant-kill mechanic removes the trailing cleanup damage on dozens of low-health targets per session. The Poison rune is Doom's ideal companion: Poison ticks enemies down toward the execution threshold while Doom handles the kill the moment they cross it. Pair this combo with the Harvest potion during resource-farming runs that also involve mob clearing to benefit from both yield bonuses and accelerated kill pace.
