💠Introduction

What’s up, folks? With so many new legendary skills already out and more on the horizon, it can become difficult to know which skills to prioritize with limited funds. In this article, we’ll take a look at one of the newest skill that just graced the game, Eternal Battlelust, what it does, its role in the meta, and whether it's worth purchasing.

💠Eternal Battlelust

Eternal Battlelust is a legendary passive built for sustained, multi-proc damage dealers. Once battle starts, every instance of passive damage or triggered skill damage ramps up your physical damage while also shaving off incoming damage, stacking up to 20 times. At base it grants 1.5% more physical damage and 0.3% reduced damage taken per proc, and at max level it reaches 5% and 1% per proc, letting heavy proc kits snowball quickly if they can keep triggering effects. In practice, the skill rewards immortals that constantly apply passive ticks or chain-triggered damage, turning early momentum into both higher output and better survivability as the fight drags on. Only ranged attackers can equip the skill.

💠Damage Increase

Since Eternal Battlelust is clearly designed for Medusa, I wanted to see if it was viable on a physical carry that does not naturally produce frequent passive or triggered damage instances, so I tested it on Apollo. To give the skill the best chance to work, I paired it with effects that could hit multiple targets and generate as many procs as possible, then compared results across repeated fights against the same opponents. In roughly 50-second battles with Energy Mastery, Eternal Battlelust, and a triggered damage skill, Apollo averaged only about 28 to 35 million total damage with around 8 to 12 ultimate casts. When I swapped Eternal Battlelust out for Apollo’s more standard damage package, specifically Energy Mastery, Corrosive Power, and Unyielding, his output jumped to about 80 to 90 million damage with roughly 12 to 18 ultimate casts. In other words, the “ramping damage” portion of Eternal Battlelust was effectively nonexistent on Apollo no matter which triggered skill I tried, and it was not remotely competitive with his optimal skill set.

💠Damage Reduction

Next I tested the defensive half of Eternal Battlelust using the same matchups and setups. With Eternal Battlelust plus a triggered skill, Apollo was taking roughly 27 to 30 million damage in 45 to 50 second fights. When I ran Apollo with his normal optimal skills instead, he took only about 13 million damage over the same 45 to 50 second window. Some of that gap is expected because the Eternal Battlelust runs were losses and losing teams naturally absorb more damage, but even with that caveat the mitigation from Eternal Battlelust did not materially improve Apollo’s survivability in practice.

💠Verdict

Eternal Battlelust is a Medusa-only skill in practice. If you do not have Medusa, it is not worth purchasing or investing resources to level, because the damage ramp and mitigation do not reliably translate to other carries and it gets outclassed by standard optimal skill sets. Do Not Buy.

💠Summary

Eternal Battlelust looks powerful on paper, but in testing it did not deliver meaningful damage or survivability on non-proc carries like Apollo and was consistently outclassed by standard skill sets. The skill’s value is heavily tied to Medusa’s constant passive and triggered damage, which actually fuels the stacks. If you do not have Medusa, Eternal Battlelust is not worth buying or leveling.
