Build complete — every recommended skill is already unlocked at 21 points.
- This is a no-reset path: every skill taken at an earlier milestone is still in the final 21-point build, so you never pay to redistribute points.
- The build is organised around Burst Fire: because the recovery after a burst is long, every reload skill is worth more here than on a conventional cruiser.
- Points are banked once, between 6 and 10, so Top Grade Gunner is bought outright instead of a cheap skill the final build would not keep.
- Eye in the Sky is an unusual pick that fits this ship specifically — Castilla fights at range with a Spotting Aircraft and no radar or smoke.
- Heavy AP Shells is taken late but is real: the 254 mm guns clear the 190 mm calibre requirement, so the skill is fully active.
- Open at long range and keep moving; your speed and flat shell arcs are what let you damage ships that cannot answer.
- Fire the burst when the target is committed to a turn — the two salvos land close together, so a broadside is worth waiting for.
- Respect the recovery time after a burst: start your turn away before the reload finishes, not after.
- You have no smoke and no radar, so never take a cap alone against a destroyer — support your own destroyers from range instead.
- Use Repair Party early and often against fire damage; HE is the damage type that actually threatens this hull.

Showing 24 of 24 cruiser commander skills , rated for Castilla.
Grease the Gears
1 ptEssential5 out of 5Improves main battery turret traverse speed.
Castilla kites constantly, so turret traverse decides how much of each burst actually lands. One point, immediate effect.
Eye in the Sky
2 ptsEssential5 out of 5Increases the action time of the Spotting Aircraft consumable.
Castilla fights at long range and carries a Spotting Aircraft; a longer spotter window turns directly into extra firing range and extra salvos.
Priority Target
2 ptsEssential5 out of 5Shows how many enemies are currently aiming at your ship.
The ship is fast but fragile to HE. Knowing how many guns are pointed at you is what keeps a kiting cruiser alive.
Adrenaline Rush
3 ptsEssential5 out of 5Reload speed improves as your ship loses hit points.
Faster reload as your health drops — and with Burst Fire on a long cycle, shaving the reload is worth more here than on a fast-firing light cruiser.
Heavy AP Shells
3 ptsEssential5 out of 5AP shell damage +5% for main battery calibre 190 mm and above.
Ineffective on main batteries below 190 mm (Brisbane B: 152 mm).
The 254 mm guns clear the 190 mm calibre gate, and Castilla's flat trajectory makes AP punishing against broadside cruisers.
Survivability Expert
3 ptsEssential5 out of 5Increases the ship's maximum hit points per tier.
Extra hit points matter on a Tier X cruiser that plays at range but is punished hard by HE when caught.
Top Grade Gunner
4 ptsEssential5 out of 5Main battery reload improves while the skill's in-game condition is met (see the skill card in port for the exact condition and value).
The signature pick: a main battery reload bonus directly shortens the long recovery after a Burst Fire salvo pair, which is Castilla's whole damage rhythm.
Last Stand
1 ptRecommended4 out of 5The ship keeps moving and steering with incapacitated engine or steering gears.
Cheap insurance for a ship whose survival depends on staying at speed.
Consumable Specialist
2 ptsRecommended4 out of 5Reduces the reload time of consumables.
Shorter Repair Party and Spotting Aircraft cooldowns; a fine two-point swap if you would rather cycle consumables than hold an extra charge.
Consumable Enhancements
2 ptsRecommended4 out of 5Increases the action time of consumables.
Longer consumable action time, which suits the long-range spotter plan.
Superintendent
3 ptsRecommended4 out of 5+1 charge to consumables, excluding those with unlimited charges and Squadron consumables.
The final three points: an extra Repair Party charge, which is the only healing a ship with no smoke and no radar can rely on.
Concealment Expert
4 ptsRecommended4 out of 5Reduces the ship's detectability radius.
A legitimate alternative four-point pick if you want to choose your engagements; this build prefers reload because Castilla wins by out-ranging rather than ambushing.
Demolition Expert
1 ptSituational3 out of 5Increases the chance of setting a fire with HE shells.
Fire chance is a real secondary income for the 254 mm HE, but this build leans on AP and reload instead.
Gun Feeder
1 ptSituational3 out of 5Reduces the time needed to switch main battery shell types.
You do switch between HE and AP, so faster switching has some value — just less than the core picks.
Incoming Fire Alert
1 ptSituational3 out of 5Warns you when shells are fired at your ship from long range.
Useful at the ranges Castilla likes; it just competes with a point that is already doing more.
Focus Fire Training
2 ptsSituational3 out of 5Improves secondary and AA performance against a priority target.
Helps against long-range fire while kiting, but it does nothing about the destroyer that finds you.
Outnumbered
4 ptsSituational3 out of 5Bonuses when several enemies are close and friendlies are not.
Castilla should not be outnumbered at close range; if it is, the skill is not what saves you.
AA Defense and ASW Expert
4 ptsSituational3 out of 5Improves continuous AA damage and ASW aircraft performance.
Take it only in carrier- and submarine-heavy queues.
Radio Location
4 ptsSituational3 out of 5Shows the direction of the nearest enemy ship.
Knowing where the nearest ship is helps a ship with no radar, but four points is steep for information alone.
Heavy HE and SAP Shells
3 ptsOptional2 out of 5HE and SAP shell damage +10%. Main battery detectability penalty applies for main battery calibre 149 mm and above.
More HE damage, but the detectability penalty for 149 mm+ guns is a bad trade for a cruiser that survives by controlling range.
Inertia Fuse for HE Shells
4 ptsOptional2 out of 5Increases HE shell armour penetration but lowers fire chance.
Only worth four points if you commit to an HE-first playstyle, which gives up Castilla's best trait.
Swift Fish
2 ptsAvoid / Inefficient1 out of 5Torpedo speed +5%.
Avoid — Castilla has no torpedo armament to speed up.
Fill the Tubes
2 ptsAvoid / Inefficient1 out of 5Speeds up torpedo tube reload.
Avoid — torpedo reload on a ship with no torpedoes.
Pack a Punch
3 ptsAvoid / Inefficient1 out of 5Torpedo damage +15%.
Avoid — torpedo damage on a ship with no torpedoes.
