How to get Alethonym catalyst in Destiny 2

The Alethonym catalyst provides a big upgrade to the powerful Destiny 2 Exotic weapon, so it’s only natural that Guardians all over would want to get their hands on it.

Episode Revenant saw all kinds of new weapons added, including Alethonym, an Exotic Grenade Launcher that uses primary ammo. Its intrinsic perk, Harvester Spike, creates remnants that can be consumed to produce either Special or Heavy ammo bricks. This makes it a great choice in high-end activities where ammo is hard to come by.

While it’s already strong on its own, the Grenade Launcher can be made even better by equipping the catalyst. However, to do so, you’ll first need to unlock it, so we’ve put together this guide breaking down exactly how to do so.

How to unlock Alethonym’s Exotic catalyst

The Alethonym catalyst is unlocked by reaching Rank 145 on the Episode Revenant Season Pass, which is now possible following the release of Revenant Act 2 on November 19, 2024.

What does the Alethonym catalyst do?

The Alethonym catalyst adds One For All to the Exotic Grenade Launcher, a powerful perk that increases damage by 35% for 10 seconds after you hit three separate enemies within three seconds of each other.

This is a strong addition to Alethonym, as you can constantly procc it by targeting clusters of enemies and hitting them all at once. It’s always going to be useful to have a 35% damage boost with little effort required, so we’d recommend unlocking this catalyst as soon as possible.
