AI LIMIT: Eirene’s Furnace of War Guide | How to Get Carven Heavemglow

A quick DLC guide for unlocking Carven Heavemglow.

Game Guide by Faviyan Mustafiz on Apr 01, 2026

If the DLC's goal is to find Carven Heavemglow, the path is clear. You can only get the weapon by beating the last battle cleanly, without taking side routes or optional detours. This is because it is tied to the Prometheus fight in AI LIMIT: Eirene's Furnace of War. That means this guide is less about exploring and more about winning the fight without losing control at the end.

Where Carven Heavemglow comes from

The Carven Heavemglow is a DLC weapon that you can get by playing Prometheus. The boss itself is the real gate, then. After you win the fight, you can get the reward through normal DLC progression. If you keep failing, the best thing to do is treat the run like a boss-clear guide first and a reward guide second.

The best way to get through the fight

The best way to beat Prometheus is to stop trying to get long combos. This boss is very hard on greedy people. Mid-range spacing is best because it gives you enough space to read the start of each attack while still keeping punish windows close. A couple of hits after a safe dodge sequence are all you need.

How to stay alive during the hard part

A lot of runs fall apart in the second half of the fight. Prometheus gets more aggressive, which usually makes you rush. The opposite is the safer answer. Wait for the whole sequence, dodge the last committed swing, and only then punish the recovery. Only after a full reset or clear distance should healing happen.

How to keep the gun safe without throwing the run

The last part of the battle should be played the same way as the first. Don't hurry because the end is near. Bad habits usually come back when your boss is sick. Stay at the same speed, avoid the full string, hit a short punish, and start over right away. The DLC reward path for Carven Heavemglow is open once Prometheus goes down.
