##Recommendations:
Mods
Primed Bane of Corpus
400 Đ + 140,000 Cr
+55% Damage vs. Corpus for Rifles. These anti-faction mods provide respectable boosts, especially since status effects double dip on them. But in normal play, they require too much micromanagement to be effective. However, there are a few activities that are both exclusively Corpus-themed and warrant a specialized build anyway, such as the Index, Profit-taker Heist and Sister hunting. If you are frequently playing these endgame activities, and have the budget to max out the mods, consider buying these.
Primed Pistol Gambit
400 Đ + 220,000 Cr
+187% Crit Chance for secondaries. Creeping Bullseye actually has a better bonus with less drain, but its reduction of fire rate means this one is still competitive for automatic crit-based pistols. Get it if you can.
Primed Quickdraw
375 Đ + 120,000 Cr
+88% Reload Speed for Pistols. Somewhat useful on battery-powered weapons, since it reduces the recharge delay. Still, very few builds can afford the cost of installing this mostly QoL mod. Safe to skip.
Primed Pressure Point
385 Đ + 300,000 Cr
+165% Base Damage. While this mod seems like a must-have, its actual improvement over the base version is a modest 30%, while costing 30 times as much to upgrade. Its main use-case is certain melees with slow and heavy attacks that forgo the use of status effects. This mod is not a bad purchase, per se, but you don't have to prioritize it when its regular version and Condition Overload offers more than viable alternatives until you reach the ends of the endgame.
Weapons
Baro's weapons typically fall into low A or B rank in tierlists, so DE at least tries to justify their asking price. And even the trashiest of weapons are worth buying if you need the Mastery Rank they provide. Or if you have good riven for them, since their disposition is usually quite high. On the other hand, Warframe has a massive arsenal, and for every weapon Baro sells, there's gonna be another that can do the same job just as well, or even better. In that sense, everything in here is safe to skip.
Prisma Ohma
450 Đ + 175,000 Cr
New! A crit-focused general upgrade to the original Ohma, at the cost of its status chance. It has some tough competition in its category, but its innate electric damage and unique stance polarity provide a distinct flavor to this Corpus tonfa.
Machete Wraith
410 Đ + 250,000 Cr
The second best machete-type melee with great riven disposition, which makes it overall decent. If you're looking to try out a machete-type, this is a good opportunity.
Zylok
500 Đ + 200,000 Cr
A lovechild of the Tigris and the Sybaris - from the wrong side of the Punnett square. It has decent base damage and high status, but with low firerate, awkward handling and awful crit, it's little more than MR fodder. It does have an augment that gives it a massive damage buff - but only on Eximus headshots. By the time you get enough Eximus spawns to keep up the buff reliably, it won't be enough to salvage the base weapon's mediocrity. It also has an Incarnon Adapter that exchanges the awkwardness of the duplex trigger for the awkwardness of fully charging each shot before it can fire on trigger release. The Incarnon mode also has a respectable AoE, and the boosted base stats from the evolutions make even the default form viable. Still kind of an acquired taste, though.
Cosmetics
Lunar Renewal Rabbit Emblem 55 Đ + 45,000 Cr
A graphic commemorating the Chinese New Year, and the then-upcoming Year of the Rabbit. Goes on your frame's shoulders. Note that its solid block of rust red cannot be recolored.
Ki'Teer Ephemera
100 Đ + 150,000 Cr
A bunch of floating lozenges around your frame. The sharp angles usually clash with the flowing, organic design of most frames, but it can be a good fit for Vauban Prime or Gara.
Ki'teer Armor Set
800 Đ + 510,000 Cr
A rather bulky armor set with the rhomboidal Ki'teer aesthetic.
Ki'Teer Diax Syandana
325 Đ + 450,000 Cr
Same design as regular Ki'teer Syandana, but with cleaner textures and no rust stains. Still distressingly rubbery.
Opticor Elixis Skin
325 Đ + 250,000 Cr
The Elixis skins cover most of the weapon in a uniform coppery/metallic texture with the occasional grid of triangular indentations. Does not always look good, but always look shiny.
Ignis Towsun Skin
300 Đ + 300,000 Cr
If you want your guns to look like they were handpainted by babushkas, this one is for you.
Ki'Teer Solo Earpiece
250 Đ + 200,000 Cr
An extremely understated earring for your Operator. For the right ear only.
Prisma Rostam Kubrow Armor
400 Đ + 175,000 Cr
Turns your pet onto an eyeless rhinoceros. Now with 187% more shiny!
Scimitar Prisma Skin
210 Đ + 450,000 Cr
Landing craft skin with large sections covered with the glossy, animated Prisma looks. Allows for some very vibrant colors, but a lot of the color channels have an unremovable bluish tint. This, combined with the unusual lighting of the customisation screen, makes it hard to create the looks you actually want.
Dvad Luxxum Ornament
100 Đ + 100,000 Cr
Abstract art for your Orbiter. Not particularly thrilling on their own, but can funtion as pedestals or part of a larger structure.
Puspa Luxxum Ornament
100 Đ + 100,000 Cr
Abstract art for your Orbiter. Not particularly thrilling on their own, but can funtion as pedestals or part of a larger structure.
Display - Argyle
100 Đ + 75,000 Cr
A poster with customizable textures and uneven, jagged edges. I'd rather just spend the plat and get the rectangular ones, but you do you.
Empyrean Vignette
155 Đ + 200,000 Cr
A centerpiece decoration for your personal quarters on the orbiter. Comes with 2 bonus Articulas. Vignettes are normally only available for plat, so if you want to fill up that empty space in the center of your room, here's your chance. But if you already put in there a nice aquarium for your fishes or a diorama with half a dozen Articulas acting out a battlescene, then don't bother, you can only have one installed at a time.
Glaring Emblem
50 Đ + 50,000 Cr
A tiny floating image of your Kavat that goes onto your shoulders.
Fae Path Ephemera 15 Đ + 15,000 Cr
One the older step-Ephemeras, and rather insubstantial compared to, say, Eros Wings or Vengeful Charge. A permanent fixture of Baro's repertoire.
I might have sharp and opinionated remarks about these items, but I'm not the fashion police. Buy whatever cosmetic tickles your fancy!
Other
If you haven't played Sands of Inaros yet, buy the quest key and do it (and bring your best setup for scanning Kavats). If you have Inaros Prime, you can buy the Baro Void-Signal (one per visit) to access some special cosmetics.
Also, check the answers below for second opinions.
That prisma ohma looks nice sadly it doesn't offers much in comparison with the other tonfas. Still picking it maybe I can do some meme build with it.
