Operation Blood of Perita Guide | Farm & What to Buy (Marks of Valiance)
Operation Blood of Perita is available for a limited time only during The Old Peace in Warframe. So, we suggest that you complete The Old Peace quest before you engage in it – since it requires a degree of experience.
How To Farm
There are two ways that you can farm the Marks of Valiance – a currency exclusive to Blood of Perita.
Perita Rebellion Game Mode
The main method of farming Marks of Valiance in Blood of Perita is by deploying in The Perita Rebellion missions. To do this, you first need to open the Dark Refractory menu from your Navigation Console.

In this menu, you should see two modes. Select The Perita Rebellion and you should see different missions that you can do to get Marks of Valiance.
You are awarded in quantities of 8-15 (10-17 on The Steel Path) Marks of Valiance from The Perita Rebellion game mode.

Operation Alerts
The other method of farming them is via Alerts that will appear every 30 minutes. They will be available for 1 hr 30 mins and involve endless missions that you will need to extract from.
You get awarded 20 Marks of Valiance (30 from Steel Path) for completing them.

Where To Buy
Once you have collected Marks of Valiance, you will want to use them to purchase different items. You can do this by heading to La Cathedral.
If you haven’t gone here yet, you will need to go to the Sanctum Anatomica in Deimos. Here, you will need to equip Drifter so you can enter through the portal. This will take you directly to the locations with The Old Peace NPCs.
Interact with Roathe and you should see an option to Exchange Marks of Valiance for a bunch of new loot.

What To Buy
There is a bunch of loot that you can purchase from Roathe that also rotates after a fixed amount of time. Here is everything that we recommend in each category:
Arcanes
Here are the different Arcanes in order of priority that we recommend:
Arcane Energize and Arcane Aegis – Recommended for beginners
Arcane Fury and Arcane Strike – Recommended for melee weapons
Arcane Rage – Recommended for primary weapons
Arcane Velocity – Recommended for secondary weapons
Besides that, you can go for whichever Arcane suits your build. Keep in mind that all Arcanes have a purchase limit of 21.
Appearance
There are a bunch of cosmetics that you can purchase here and it totally is up to you. We recommend getting the Enlightened Hate Skin since it stands out from the rest!
Miscellaneous
Here is every misc item we recommend getting:
Of Golden Valor Honoria – More than likely exclusively to this event and won’t be coming back again
Additionally, you will also want to get the Lens but do that later on when you have extra Marks remaining.

Wrap Up
That’s everything you need to know about the Operation Blood of Perta guide when it comes to farming and buying the new items. This event is only available for a limited time – so we recommend getting the important stuff during your grind. After that, you can get the rest of the items as you start to accumulate more Marks. The rewards do rotate as well so keep that in mind when you’re buying stuff from Roathe.
