Serina is a current Pax Autocratica player-search intent, but the available first-party material does not publish a reliable complete attack list, phase script, resistance table, sector location, or reward table. This page therefore gives a safe method for the live public-branch encounter and clearly leaves unverified specifics to the game you can see.
Verify that the encounter is Serina
Record the exact name shown by the mission, objective, target panel, or result screen. Also note the sector or destination, difficulty, active objective, and current directive date. Do not identify the encounter from a pre-release thumbnail or a community title alone.
Keep the access sequence with the record. If a later save cannot reach Serina, compare mission and progression states rather than assuming a hidden permanent lock.
Prepare a reconnaissance squad
Save before departure, leave the colony’s essential jobs covered, and bring a formation that can hold position, focus a priority, and withdraw. Favor readable, controllable actions on the first attempt. Avoid several large effects that cover the boss cues you are trying to learn.
Build the attack record from earliest cues
For each repeated attack, note where Serina begins, the earliest visible or audible cue, which direction the action develops, whether it tracks, how much space it covers, whether another action follows, and when movement becomes safe again. Record only behavior reproduced in the current encounter.
Do not rush to name phases. Instead, note the exact state change: a new indicator, location, add, objective, animation set, or arena behavior. This keeps the guide useful even if the interface does not formally divide the fight.
Account for the current indicator fix
Directive AG-12 included a fix involving a Serina-related indicator. That confirms an indicator issue existed in an earlier Early Access state, but it does not prove every present visual problem has the same cause. If an indicator is missing or impossible, record the exact trigger and current branch before changing tactics around it.
Preserve a save from before the state change. If the issue repeats, report Serina, the mission, current settings, and what the indicator did or did not show.
Refine one failure at a time
If the Leader cannot read a cue, increase observation distance or reduce visual clutter. If soldiers split, simplify the anchor. If an opening is too short, use a smaller action. If the encounter crashes, stop tactical testing and follow the technical sequence in Crash Fixes.
After a successful attempt, return to the mission and result panels before naming a reward or progression effect. Record what the game grants and what changes on the Star Map. This closes the Serina entry with evidence from access through outcome, rather than ending the guide at the final hit.
Do not publish a “best” weapon, core, resistance, reward, or phase count from one successful run. Add those facts only when the current public branch and repeatable evidence support them. The general Boss Guide covers the broader method; Squad Builds helps rebuild the formation without inventing Serina-specific counters.
