What named creators run on Iana, and every option the game allows. Plus the gadget interactions that decide the matchup.
Primary and attachments: NotJoeyBlack's pick.
Rainbow Six counters are gadget interactions, rules of the game rather than statistics, so every pairing here comes from the two operators' own kit pages: the mechanism from whoever wins it, the gadget it beats from whoever brings it.
The Gemini Replicator fools anything that looks. Pulse's HB-5 Cardiac Sensor reads a heartbeat, and a hologram does not have one, so he clears the copy and finds the body.
Both operators sell a fake. Prisma marks whoever shoots or touches a hologram, so Iana's Replicator, which cannot shoot back, walks into a decoy that reports her position instead of collecting one.
Iana scouts with the Replicator and its cooldown runs longer when it is destroyed. A Razorbloom Shell in the room fires on proximity, so scouting that room costs her the gadget for longer than the intel was worth.
A Pest latches onto the nearest enemy drone. The Gemini Replicator is a hologram, so it walks the exact route Mozzie set up to deny and there is nothing on it to hack.
Skopos can only run one Pantheon Shell at a time and loses both if one dies. A Replicator in the other room pulls her to the wrong shell and costs her nothing to kill.
Iana is an Attacker in Rainbow Six Siege.
Rainbow Six's counters are mostly deterministic gadget interactions, rules of the game rather than statistics, so we state them from the two operators' own kit pages with no telemetry needed. A pairing is only written where the winning operator's page names the mechanism, which is why plenty of operators here carry none. Statistical data is based on external APIs and publicly available information. It may differ from official data.
NotJoeyBlack, SINOOS and Rasco100 publish loadout picks under their own name, and this page credits each of them rather than averaging them into a single answer. We measure nothing ourselves. The list of what Iana can equip is the game's own, and is separate from anyone's opinion about it. Statistical data is based on external APIs and publicly available information. It may differ from official data.
