Jae Heydari Build Guide (Rogue Trader)
TL;DR: Run Jae as an Officer into Master Tactician for big personal damage off your party's Momentum, or Overseer for AoE officer buffs. Stack Fellowship above everything, recruit her in Chapter 2, and pair her with Cassia as your second Officer to double the extra-turn engine. Built well, she earns her "stupid overpowered" reputation.
Build: 03df5849ffd0Who Jae Is
entity:jae Heydari joins the dynasty in Chapter 2 with a Cold Trader origin out of an entity:imperial-world. Her starting Archetype is entity:officer and it is fixed, so you cannot reclass her at tier 1. What you get to choose is her tier-2 path, her stat priorities, and her full talent and skill spread. That fixed Officer chassis is exactly what you want here. Officer is the most famous mechanic in the game, and the action-economy tricks it unlocks are why Jae sits in the A tier of the companion rankings, right alongside entity:idira and entity:kibellah.
Her Cold Trader origin bonuses are what push her above other supports, to the point the community calls her "stupid overpowered" when she is built well. She is the ranged counterpart to what Kibellah is for melee. The one caveat: her Officer build rewards careful optimization rather than autopilot, so the choices below matter.
Fellowship First, Always
Fellowship is everything for an Officer. Most officer abilities scale off the Fellowship bonus, so FEL is the stat you pump at every opportunity, with Willpower as a secondary. Every point of FEL widens the damage floor on your command abilities and tightens the buffs you hand your carries.
The core entity:officer engine runs on two abilities. entity:voice-of-command applies a buff target. entity:bring-it-down then grants a marked ally an attack that ignores cover, doubles effective range, and, on a Voice-of-Command target, ignores dodge with a damage floor of (30 + 3 x FEL bonus)%. That floor is the whole reason FEL dominates her sheet. Stack those two abilities on your hardest-hitting damage dealer and you frontload an entire round of damage before the enemy acts.
The Tier-2 Choice: Master Tactician or Overseer
Jae's build comes down to one fork at tier 2, and both paths are strong.
Master Tactician is the personal-damage route. It converts the party's high mid-to-late-game Momentum into a large personal damage buff and group attacks. By Chapter 3 the game's difficulty is carried by alpha-strike damage and prevention, so a support character who also hits like a carry is enormous value. This is the pick when you want Jae buffing the party and then adding her own damage on top, rather than sitting idle once her commands are spent. It scales with party Momentum instead of fiddly positioning, which keeps her clean to play.
Overseer is the AoE officer-buff route. Where entity:master-tactician turns Jae into a hybrid damage threat, entity:overseer leans into spreading officer buffs across the group. Take this when your party already has its damage covered by entity:cassia and entity:argenta and you want Jae multiplying everyone's output instead of adding her own.
For most players chasing the ceiling, Master Tactician is the headline pick because it removes the old problem of the support character being dead weight on offense. Overseer is the answer when your composition wants pure force-multiplication.
Running Two Officers: Jae Next To Cassia
The single best thing you can do with Jae is run her as your second entity:officer next to entity:cassia. Cassia is the consensus number-one companion in the game, a Navigator whose entity:lidless-stare line clears most random encounters in a cast or two. She is also an Officer at her core, so stacking a second Officer doubles the engine.
The officer kit breaks the action economy. entity:bring-it-down plus the officer heroic act can hand a damage character two extra turns in a round. With two Officers feeding that loop, you are handing out extra turns from both sides of the party. With entity:paradox-solved (the heroic act costs no momentum) plus Iconoclast Rank 4, an Officer can buff, entity:voice-of-command an ally, and Bring It Down a second ally all in one turn. Double that across Cassia and Jae and you collapse hard fights into a single alpha strike.
One balance note worth knowing: patch 1.1.28 reined the engine in. Bring It Down! can no longer hit the same ally more than once per round, and officers can no longer farm Momentum from repeatedly granting bonus turns. The double-officer setup is still S-tier in practice; it is simply no longer infinite. Build around marking your two best carries rather than chaining one.
Stat and Talent Priorities
Pour points into Fellowship first and Willpower second. FEL drives every command, the Bring It Down! damage floor, and the strength of every buff she lays down. Willpower backs up her resilience and the morale side of the officer toolkit.
On talents, prioritize anything that deepens the entity:voice-of-command and entity:bring-it-down loop, then the Momentum payoff if you went Master Tactician. The Cold Trader origin bonuses do the heavy lifting on top of those choices, which is the secret behind her tier placement. You are not fighting the build; you are stacking FEL and pointing her commands at the right ally every turn.
Romance and Recruitment
Jae joins in Chapter 2, which means she lands while your party composition is still forming and there is room to slot her in as the second Officer from the moment she arrives. She is romanceable by any Rogue Trader regardless of gender, so she fits any playthrough without locking you out the way some companions do.
Where Jae Fits In Your Party
Jae's job is to make your carries hit twice and hit harder. With entity:master-tactician she does both for the party and for herself; with entity:overseer she pushes pure buffs across the group. Either way she belongs in a party built around alpha-strike damage, sitting next to entity:cassia so the extra-turn engine fires from two officers at once.
