Who Tiza is and why you’d want him
Tiza is a Common, Command-class officer in the Mudd’s Company group, on the Neutral faction list. The reason to pay attention to him is narrow but clear. Both of his abilities target Eclipse hostiles, the same enemy type players grind for Exchange materials. If you fight Eclipse ships on a regular basis, Tiza pulls real weight despite the low rarity.
Tiza is also one of the cheapest Eclipse-focused officers to recruit. Common officers cap out at a small shard pool, so getting Tiza to max rank costs a fraction of what an Epic equivalent would. That makes him a useful early answer for any account that wants to grind Eclipse content without burning through premium recruits.
Star Trek background
Tiza is not pulled from any Star Trek series. The character and the Mirani species were introduced inside Star Trek Fleet Command as part of the Eclipse storyline, the same arc that brought the Exchange and Mudd’s Company to the in-game universe. There is no Memory Alpha entry for him, which is helpful to know upfront so you don’t go hunting for canon context that doesn’t exist.
The lore the game gives is simple. The Mirani were a tech-forward species who lost their home space to Eclipse roughly a century ago. A handful of survivors escaped and rebuilt on abandoned planets. Tiza now leads what’s left of them and wants their old systems back. That motivation is why every Tiza ability points at Eclipse and only Eclipse.
Tiza’s role in STFC
Tiza sits in a small bucket of officers built specifically to counter Eclipse hostiles. He is not a generalist. Putting Tiza on a ship hunting Klingons, Federation, or Romulan targets gives you nothing. Putting him on a ship hunting Eclipse hostiles or Eclipse Armadas gives you two layered bonuses: a small offensive nudge on the captain side and a real survivability boost on the officer side.
Because both abilities live in the same Eclipse niche, you can run Tiza in the captain seat or as an officer slot depending on what your other crew slots need. The better use of him is on the bridge as an officer, not as captain, and the next section explains why.
Security Breach (captain ability)
Security Breach is Tiza’s captain maneuver. When fighting Eclipse hostiles, including Eclipse Armada Targets, it cuts the opponent’s Shield Mitigation by 4% in the opening of combat (as of the latest game data). Cutting Shield Mitigation makes more of your weapon damage land instead of being absorbed, so the effect shows up as a slightly faster time-to-kill on Eclipse targets.
Two caveats are worth flagging. First, the rank-1 value is the safe number to quote; the in-game data does not present a clean per-rank table for this captain ability, so don’t expect the cut to scale dramatically with promotions. Second, the bonus is restricted to the opening rounds, so it helps most on Interceptors and other ships that close the fight quickly. On a long slugfest it has less time to matter.
Mirani Technology (officer ability)
Mirani Technology is the headliner. When Tiza is on the bridge as an officer (not captain) and you engage an Eclipse hostile, including Eclipse Armadas, he has a chance to double Shield Deflection, Armor, and Dodge for the entire combat. The chance scales with rank.
The per-rank chance values are consistent across sources and form a clean monotonic progression, so a per-rank table is worth showing (current as of the latest game data):
| Rank | Chance to trigger |
|---|---|
| 1 | 35% |
| 2 | 45% |
| 3 | 55% |
| 4 | 65% |
| 5 | 75% |
Two things to remember. The ability is a chance, not a guarantee, so even at rank 5 about one fight in four won’t trigger it. When it does trigger, the +100% to all three mitigation stats lasts the whole combat, which turns survivable Eclipse fights into very forgiving ones. That dynamic is what makes the rank-up path worth it for any account running daily Eclipse content.
One more piece of context. Shield Deflection, Armor, and Dodge are three separate defensive stats in STFC, not a single bucket. Doubling all three at once is a real spike in effective HP, even if individual stats stay relatively low.
Where Tiza is worth slotting
A few situations where Tiza earns the seat:
- Daily Eclipse hostile grinding for Exchange materials. The mitigation chance turns a defensive crew into something that can take repeat hits without expensive repairs.
- Eclipse Armada runs. Both abilities call out armadas explicitly, so Tiza is not restricted to solo hostiles and contributes inside group content too.
- Lower-tier players who do not yet have access to higher-rarity Eclipse-specific officers. Common shard sources are cheap, so Tiza is one of the first usable answers to the Eclipse threat curve before bigger names show up in the roster.
Outside of that, Tiza does not add much. Skip him on faction-grinding crews, station defense, mining ships, and any combat against non-Eclipse hostiles. Officers built around a single hostile type live and die by whether you actually fight that hostile, and Tiza is no exception.
How to get Tiza shards
Tiza is a Common officer, and the shard ladder from recruit through max rank totals 200 shards. The promotion costs are 10, 15, 35, 65, and 75 shards for ranks 1 through 5, in that order. Max level by rank is 5, 10, 15, 20, and 30.
For shard sources, check current event and faction store availability inside your build of the game. Common officer rotations shift over time, so the specific store or event that drops Tiza shards today may not be the one that drops them in a few patches. The good news is that Common officers tend to show up in starter recruit pools and low-tier chests, so casual play often fills out Tiza’s shard pool without targeted farming.
Synergies and crew building
Tiza’s class-synergy bonus is small. Putting him in the captain seat adds 1% to Command-class officers, 2% to Engineering-class officers, and 2% to Science-class officers. Those numbers are useful to know for completeness, but they are not the reason you would run Tiza.
The reason is Mirani Technology. Build the crew around Tiza-as-officer, with a captain whose maneuver also helps against Eclipse hostiles, and do not worry about squeezing extra synergy points out of the captain seat. Two officers stacking Eclipse-focused effects on the same ship is more valuable than chasing a 1% synergy bump.
The other two officer slots are open. The source data does not lock in any specific named pairing for Tiza, so general advice fits best here: pair with another defensive Eclipse-focused officer in the second slot, and a captain or third officer that boosts the damage type your ship uses (Kinetic, Energy, or Explosive). Avoid copying named crews from older guides without checking whether those officers still match your current event meta.
Frequently asked questions
Is Tiza worth ranking up?
If you fight Eclipse content as part of your daily play, yes. The chance to trigger Mirani Technology goes from 35% at rank 1 to 75% at rank 5, and the cost to climb that ladder is low compared with higher-rarity officers. If you never fight Eclipse, no.
What ship is Tiza best on?
Any ship you regularly send into Eclipse fights. Mirani Technology raises Shield Deflection, Armor, and Dodge, so it benefits hulls where those defensive stats matter (Interceptors and Battleships gain the most). The captain ability is shorter-lived, so it tilts toward faster ships that close range quickly when it sees use.
Does Mirani Technology work on Eclipse Armadas?
Yes. Both the in-game text and the source data list Armada Targets in the same Eclipse bucket, so the chance to double mitigation applies in armada combat the same way it does on solo hostiles.
Captain seat or officer slot?
Officer slot, almost every time. The captain maneuver is a small first-round Shield Mitigation cut on the enemy and does not present a clean per-rank scaling, so it caps out quickly. Mirani Technology on the bridge is the bigger lever and what justifies the rank investment.
Where do Tiza shards come from right now?
Check the current store and event rotations inside the game. Common officer shards rotate frequently, and pinning the answer to a single source would go stale within a patch or two.
Bottom line
Tiza is a focused tool, not a flexible one. If you grind Eclipse hostiles, he belongs in the rotation early because the shards are cheap and Mirani Technology pays out. If you do not fight Eclipse, he sits on the bench. Look at your weekly objectives, see how many Eclipse fights you are actually running, and rank Tiza up only as far as your usage justifies.
