Core problem: Farm enough Orokin Ducats and Credits before Baro leaves, and spend them on the right items without wasting resources. Baro's stock rotates - miss it and you wait two weeks.

Step-by-Step Guide

1
Confirm you can access Baro

Go to Larunda Relay (Mercury). Confirm your Mastery Rank allows entry. New players sometimes farm Ducats they can't spend because they never checked access first.

2
Farm Ducats and Credits if low

Ducats (the bottleneck): Run Void Fissure missions - Omni-Fissures are best for group play. Open Relics, then sell Prime parts and junk at Ducat kiosks in any Relay. Use Radiant relics for better high-Ducat drops. If short on time, buy "Prime junk" from Trade Chat with Platinum.

Credits: Run The Index (find groups in Recruitment chat). Sell duplicate mods and inventory junk for quick credit gains.

3
Buy in priority order

See the priority list below. Always grab Void Surplus first - it costs zero Ducats and only 50k Credits, once per visit.

4
Use community planning tools

Read the main r/Warframe Baro thread for TL;DR recommendations. Google Sheets masterlists (linked in Reddit posts each visit) show full Ducat costs and totals so you can plan your budget before walking up to Baro.

Buy Priority List

Always grab first

Buy
Void Surplus
0 Ducats + 50k Credits. Once per visit. Lootbox with materials, boosters, currencies, and a chance at an exclusive Signa. Nearly free - always take it.

High-priority mods (power spikes)

Mod
Primed Reach
+3m melee range. Massive QoL and damage increase for almost all melee builds. Top priority for anyone who melee.
Mod
Primed Fever Strike
High Toxin for melee elemental builds. Core for many endgame melee setups.
Mod
Primed Pistol Gambit
Crit chance for secondaries. Especially strong for Mesa builds and high-crit secondary setups.
Mod
Primed Smite Corpus
Situational but solid for Corpus-focused or endgame Corpus content. Lower priority unless you run Corpus missions heavily.

Weapons and Sentinels (MR and utility)

MR
Prisma Shade
Good MR, stealth utility. Solid sentinel pick if you don't have it.
MR
Quanta Vandal
MR plus a solid primary weapon. Worth buying if missing for Mastery.
MR
Prisma Obex
Community highlights potential value with its upcoming Incarnon. Buy now if you need MR.
MR
Prisma Twin Gremlins
MR plus fun secondary. Good pickup for Mastery hunters.
Relic
Neo O1 Relic
Good for Volt Prime parts, which remain relevant in parts of the meta.

Skip or low priority

Cosmetics (fashion, buy if Ducats allow)

Optional
Eos Prime Armor Set
Discounted bundle this visit. Good fashion value.
Optional
Velibreaker Login Music
New this visit. Buy if you want it before Baro rotates stock.
Optional
Sands of Inaros BP
Buy if you are missing the Inaros quest or want the frame. Otherwise skip.

Key Decision Points

New Player
Weapons and sentinels first
Prioritize MR items - Prisma weapons, sentinels, relics. Mastery Rank unlocks gear and systems faster, which matters more than any single mod early on.
Veteran
Primed mods and fashion
Go straight to Primed Reach and Fever Strike if you don't have them. Then cosmetics. MR weapons are low value when you're already ranked up.
Ducats Tight
Mods first, then Void Surplus
Primed Reach and Fever Strike, then Void Surplus (it's nearly free), then cosmetics. Weapons can wait if you don't urgently need MR.
Prisma Obex
Worth buying now
Community is flagging Prisma Obex for its upcoming Incarnon potential. If you don't have it, buy it now before Baro rotates it out.
Tennocon prep: If you are planning to attend the Tennocon relay (ticket required), stock up on Ducats now for bulk buying at the special Baro visit during Tennocon.

Common Mistakes to Avoid

x Buying everything indiscriminately. Spending Ducats on low-use items like Fanged Fusillade or niche cosmetics drains your budget. Stick to the priority list.
x Ignoring the Credits cost. Many items cost both Ducats and Credits. Check your Credits balance before you go - some players run out mid-purchase.
x Missing Void Surplus. It is once per visit and costs almost nothing. Always grab it before leaving Baro.
x Farming solo non-radiant fissures. Group Omni-Fissures are significantly faster for Ducat farming. Use Recruitment chat to find groups.
x Waiting too long. Baro leaves after ~48 hours. If you need Ducats, start farming the moment Baro arrives - don't leave it to the last day.
