Warframe sets an industry-wide example when it comes to building a fair free-to-play live service game model. Save for a handful of founder-exclusives, all items can be obtained by a f2p player. The tradeoff for this availability is the fact that not all the items are readily available. The biggest example of this is Primed Mods. Unlike Prime Warframe and Weapon components, the Primed Mods can only be obtained from Baro Ki'Teer, the Void Trader.
Admittedly, you can always acquire these items from other players via trade chat. For those who want to play solo or prefer acquiring items from their direct drop sources, almost all of Baro Ki'Teer's merchandise is uniquely accessible only from his inventory.
Where to find Baro Ki'Teer in Warframe?
For this week, Baro Ki'teer can be found in Strata Relay (Earth). He will be stationed in the central hub room of this Relay until Sunday (June 1, 2025).

To find Baro, go to the Relay, open up the fast travel wheel by holding down 'Q', and then click on 'Void Trader' to the left.
How to buy items from Baro Ki'Teer in Warframe?
All items on Baro Ki'Teer can be bought for a combination of Credits and Ducats. Credits can be farmed from many sources in the game, as it is the most common form of currency.
Ducats, on the other hand, can only be obtained from the Void Trader's Ducat Kiosks located in any Relay. Unlike Baro Ki'Teer's stock, the Ducats can be acquired any time of the week, as the kiosks are always operational.

Ducats can be purchased in exchange for Primed Parts for weapons and frames, obtained by cracking Void Relics from the four eras. The Ducat price for a Primed part is determined only by its rarity in the Relic.

Warframe Baro Ki'teer recommendations: What should you get this week?
For this week's Baro-exclusive non-cosmetic items, the order of priority for an average player should be:
- Sands of Inaros blueprint if you haven't done the quest (an excellent source of Kavat Genetic Codes)
- Primed Flow
- Primed Charged Shell
- Primed Bane of Corpus
- Primed Rubedo-lined Barrel
- Primed Sniper Ammo Mutation
This week's Baro offerings are quite skippable on the whole, since none of the mods are exactly game-changing. Primed Flow would be the first-priority purchase, since it's the most slot-efficient way to increase your max Energy.
Even outside the utility of having a large energy pool, there are other niche applications, for example, Violet Archon Shards for Melee Crit Damage (which gets doubled with 500+ Max Energy).
Speaking of Violet Archon Shards, they are great for granting Electricity damage on Primaries. This greatly decreases the value of Primed Charged Shell, so if you're dedicated to grinding combo Shards from Hollvania content, ETA, and Netracells, you can skip this one.
Other than making Elemental combos, these mods are great in two specific niche use cases: Saryn (Toxin with Toxic Lash scaling) and Cyte-09 (any Element). Here's an example build for Cyte-09 with Sobek that pays insane dividends.
Primed Bane of Corpus is useful for double-dipping faction damage with status-based weapons (e.g. those using heat-Inherit setups). In practice, this is only good if you run very long Disruptions in Lua to farm Axi Relics.
Primed Rubedo-lined Barrel is a base damage mod for Archguns, which makes it useless for its niche application in Warframe right now. The use case in question is Profit-Taker, where it's meta to use Chroma, who increases your base damage through Vex Armor anyway.
Primed Sniper Ammo Mutation is an even more niche pick, since you could just use Vigilante Supplies in most cases.
Another offering this week is the Neo O1 Relic, which can potentially drop some Aklex Prime, Volt Prime, and Odonata Prime components. However, due to the high price per unit, you should only spend your Ducats here if you have everything else in the bag already.
Which Baro weapon is worth taking from this week's Baro rotation in Warframe?

Out of the lot, Ignis Wraith is the best Baro weapon for general utility. Here's a breakdown of the options:
- Ignis Wraith: Funnily enough, the best Baro offering this week is one not worth buying. You get this for free in a huge number of clans these days, or you can just ask a friend whose clan has it.
- Supra Vandal: Cool old-school corpus pew-pew assault rifle, but nothing special in terms of power.
- Halikar Wraith: Despite having a big base damage, this is just about the worst Glaive-type melee out there.
