How The Impetus Repository Works

To use the Impetus Repository, you’ll have tovisit a Shrine.

You cannot gain new skills, change skills, or refine Red Mercury unless you are at a Shrine. Once you offer prayers to a Shrine,simply toggle to the Impetus Repository Menuto view all available skills and Red Mercury Essence points.

Once you’ve refined Red Mercury Essence,you can spend this Essence like skill pointsto unlock new abilities.

You can alsoalways reset the way you’ve spent your Red Mercury Essenceif you desire.

When you do so, you can redistribute your skill points if you see fit. This is great if you want to use a particular weapon for a difficult boss encounter, but don’t have the right skills unlocked.

How To Earn Red Mercury Essence

In order to unlock new abilities in the Impetus Repository, you’ll need torefine Red Mercury Essence. As mentioned, this requires you to find a certain amount of Red Mercury out in the open world.

If you are killedout in the world,you will drop any Red Mercuryyou have collected.

You’ll then need to return to the same spot to recollect your Red Mercury. If you are killed again, you won’t be able to regain that same Red Mercury.

In thetop right-hand corner of your screen, you cansee how much Red Mercury you’ve acquired.

When you have enoughto refine into Red Mercury Essence,the icon will glow slightly.

When you see this icon glowing,head back to a Shrine as soon as you can to refine it into Red Mercury Essence, subsequently spending it on a skill or build upgrade.

Once you’ve refined Red Mercury into Red Mercury essence, it never goes away.

However,if you drop your Red Mercury before it is refined, you risk losing it forever.

Where To Find Red Mercury

There are a number of ways to find and earn Red Mercuryin Wuchang: Fallen Feathers.

Defeating enemies is the most surefire wayto earn Red Mercury. Every time you defeat an enemy, you’ll notice your Red Mercury tracker go up. Obviously, the more powerful the enemy, the more Red Mercury you earn.

However,sometimes you earn Red Mercury just for entering new areas. Additionally, you can alsofind Red Mercury items like Red Mercury Shoots.

Red Mercury items contain Red Mercury, but you mustuse them first to add them to your Repository.

Simply head to the items screen and select ‘use’ on the Red Mercury itemof your choice to add their Red Mercury to your pool.

This is a pretty easy combo to hit, so this skill is a great way to earn Skyborn Might quickly.

Boldheart

This makes your spear a much more viable weapon early on.
