Commander

Revision as of 20:46, 15 February 2019

The Commander recruitment window.

Recruiting

Once Account Level 7 is unlocked, a ship may not be queued for battle without a commander assigned to it. Thereafter, a commander can be recruited for a ship without one.^[1] There are several options offered when recruiting a new commander:

• Send to a Senior Commanders Course for 25 to earn three (3) skill points.
• Send to the Naval Academy for 7,500 to earn one (1) skill point.
• Be content with Basic Training at no cost for zero (0) skill points.
• Clicking the small, circular icon below the commander's name (middle left) in the recruitment window generates a new name and portrait for the commander. This can be repeated until the player is satisfied with the combination.

Recruiting is not the only way to obtain commanders. Certain missions, campaigns, and Scenarios award commanders. Experienced commanders can be bought in the Arsenal for Coal or Doubloons, or from the Premium Shop for real money. Awarded ships and some purchased ship bundles include experienced commanders.

When a ship is purchased from the tech tree, it can be with a newly recruited commander or without one. The latter option is useful when you intend to assign a commander from Reserve or another ship.

Managing Commanders

Clicking on the Commander portrait in the top right of the Port screen brings up the Commander interface. This screen allows players to manage their Commanders in various ways.

The Commander Interface: current skills (Red 1), redistribution (Orange 2), reserve Commanders (Green 3), current Commander (Blue 4), and Elite Commander experience (Purple 5).

The currently selected Commander is shown in the top right; the Commander skills trained are shown in the center. The drop down menu next to the Commander's name allows players to assign the Commander to another ship, send him to Reserve, dismiss him, or Go to their Personal File. Directly below the currently selected Commander is shown other Commanders that are eligible for use on the selected ship. The toggle at the top shows either commanders currently assigned to other ships, or those that are in Reserve.

The center of the Commander Interface displays the Commander skill tree — discussed in detail below — with currently trained skills highlighted. At the far left is the Redistribute function, that allows players to "respec" their Commanders by clearing their skill selections and allowing all skill points earned to be assigned again.

Commander Skill Points

The crux of the Commander system — and the main portion of the Commander interface — revolves around the various skills available to train. Players accomplish this by earning Commander experience, then spending that experience on Commander skills.

Commanders who have available skill points to spend will show unspent points in the Port screen.

Earning Commander Experience

Commanders earn commander experience (CXP) in the same way that ships do, including any bonuses to ship XP earnings. Additional bonuses that affect only commander XP — such as from Restless Fire  camo or the Zulu Hotel 🚫 signal — are added on top of this number. Therefore, it is possible to earn considerably more commander XP in a match than ship XP. See the Economics article for details of how CXP is calculated. Players can view how much commander XP they earned in a given match on the 'Credits and XP' tab of the post-battle report.

The table at right shows the experience requirements for a Commander to buy skill points.

The skill confirmation window.

Spending Commander Experience

Each commander displays his skill points overlayed on his portrait as available/total. Thus a commander with 15 points, only 3 assigned, would show "12/15" on the lower left of his portrait. Clicking on the commander's portrait brings up the Commander Interface screen (see the graphic above), where a new skill may be selected. The interface will ask for confirmation.

Some skills are only useful to certain classes or to ships with certain weapon systems. Skills that are not useful to the current ship are marked as such. They may still be selected. (If a skill is not useful on the current ship, it may become so when the commander is moved to a different ship.) However, considering the amount of time it takes to train a highly skilled Commander, it is best to focus his skills on ones that are immediately useful. A complete list of skills, their point cost, and effects appears below.

When training skills in Rows 2, 3 or 4, Commanders must have at least one skill trained from the previous row. Commanders are free to train any skill in a row before selecting any skill in the subsequent row; they are not confined to skills only within the sub-groupings shown below (and in the skill tree in the Commander interface).

Table of Commander Skills

Main article: Commander

Battleship skills  •  Cruiser skills  •  Destroyer skills  •  Aircraft Carrier skills ^[2]  •  Submarine skills

While a commander is re-training (specializing to a new tech-tree ship), his skills will not function on that ship. They will function on premium and special ships.
Further, while he earns Commander XP, he does not earn 5% Elite Commander XP .

Redistribute Commander Skills

Players will sometimes want to change the skill selections on one of their Commanders. This is accomplished in the Commander Interface by utilizing the "Redistribute" button (shown highlighted in orange on the graphic above). Redistributing Commander skill points costs either 25 or 10,000 Elite Commander XP per spent skill point; players are not charged to redistribute unspent skill points. Upon confirming the redistribution, all currently trained Commander skills are cleared, the corresponding skill points are refunded, and players may begin assigning those skill points again as they see fit.

Note that when using Elite Commander XP, up to level 7 it is cheaper to recruit a new commander and accelerate their training than to redistribute skills of an existing commander. This will also result in two commanders instead of one.

On occasion — such as Christmas or other holidays — Wargaming offers sales on redistribution. Clan Battle participants have been enjoying one week of free redistribution at the beginning and at the end of Clan Battle seasons.

Reserve Slots

Reserve slots — (shown highlighted in green on the graphic above) — hold unassigned commanders. Commanders in the Reserve can be assigned to any ship (of the same nation) as normal, subject to re-training costs (see below).

Each player starts with four (4) Reserve slots. Additional Reserve slots can be purchased with doubloons -- normally four (4) slots for 100. Slots are very rarely available though other means.

Retraining Commanders

Once trained to a non-premium ship from the tech tree, a Commander's skills can be fully utilized only on that ship. Transferring to a new tech tree ship requires the commander to re-training to that ship, which is usually accomplished by earning a certain amount of Commander XP in his new ship (see the table to the right). Normal commander training resumes once re-training has been accomplished.

When re-training is required, players are offered several options. Commanders can spend:

• 500, completing re-training instantly.
• 200,000, requiring them to earn 1/2 the Commander XP normally required (see table) to completely re-train (or spend the full amount of doubloons).
• nothing, requiring them to earn Commander XP in order to fully re-train for their new ships.

Commanders can also spend Elite Commander XP (and/or Free XP) equal to the remaining cost of re-training, finishing re-training instantly. This can be combined with the 200,000 option in order to save ECXP.

Premium Ships

A commander can be assigned to a premium ship of the same nation at any time without undergoing re-training. His skills will continue to work at full strength on the premium ship. Commander XP earned while assigned to a premium ship counts toward re-training on his specialized ship. This makes premium ships a great way to re-train commanders while avoiding retraining penalties. The commander can be moved back to his specialized ship without penalty.

Elite Commander Experience

No commander can earn more commander experience (CXP) than the amount needed for 19 Commander skill points. One who earns 19 points becomes an Elite Commander. All XP earned by Elite Commanders becomes Elite Commander XP (shown highlighted in purple on the graphic above). Elite Commander XP (ECXP) does not accumulate on the earning commander but is added to a common pool on your account.

Using Elite Commander XP

Elite Commander XP can be:

• Applied to any non-Elite Commander to gain additional Skill Points.
• Used to retrain any non-Elite Commander moved to a different ship (instead of spending doubloons).
• Used to reset all mastered Skills (in lieu of using doubloons)
• Converted into Free XP for doubloons.

How to Spend Free XP on Commanders

Free XP can be used in the same way as Elite Commander XP. After all ECXP is spent, Free XP can be spent:

• on promoting any non-Elite commander to the next rank, thus increasing his number of Skill points.
• to retrain a Commander, when assigned to a different ship, to 100% (instead of using doubloons.)
• on resetting all Skills mastered by a commander (in lieu of spending doubloons). (See Restistribute Commander Skills above.)

Elite Commander XP and Free XP can be spent together, like the way Ship XP and Free XP are spent on researching ships and ship modules.

When Elite Commander XP and Free XP are spent, the following rules apply:

• To retrain a Commander, promote him to a new rank, or redistribute his Commander Skills, the available Elite Commander XP and/or Free XP should be sufficient to fully complete such an operation (for example, to re-train a Commander to 100%).
• When an operation can be completed, Elite Commander XP is spent first and Free XP is used only if there is not enough Elite Commander XP available.

When training/re-training a Commander, the total amount of Elite Commander XP and Free XP spent is equal to the amount of the Commander's own XP (Commander XP) required to train this Commander to a 100% level or earn the next Skill point. The total amount of Elite Commander XP and Free XP required to reset Commander Skills equals the amount required for such resetting.

Conversion of Elite Commander XP to Free XP

Elite Commander XP can be converted to Free XP in the same way as Elite (ship) XP -- ( 25 ECXP + 1 => 25 Free XP ). Free XP cannot be converted back to Elite Commander XP.

Access to Operations Involving Elite Commander XP

Elite Commander XP and Free XP become available for leveling up Commanders at Account Level 7, where the Commanders feature itself becomes available. However, Elite Commander XP can be spent only after it's been earned. Unlike Elite Commander XP, Free XP is already accessible to players before the Commanders feature is unlocked. Because of this, Free XP can be spent as described above before any Elite Commander XP has been earned.

Unique Commanders

Some commanders have unique talents or modified commander skills. Check out the list of unique commanders to learn more.

Commander Ranks

As a Commander gains levels, they are given ranks based on their nation. These roughly correspond to the historical ranks awarded to officers of their nation's respective navies. The table below lists these ranks as they appear in game.

Notes

1. ↑ To recruit a commander to Reserve, temporarily move the commander of a ship to reserve, recruit a new commander, then swap back.
2. ↑ Aircraft Carrier skills do not apply to hybrid ships such as Ise and Tone.
3. ↑ ^{3.0 3.1} When activated, the continuous AA damage in the priority sector instantly gains 25% and rises to its default maximum plus 25%. Meanwhile, the weak side loses an additional 25%.
4. ↑ Secondary target designation can be tricky at first. To make it more sure, with the Alternate Interface Mode set to Full (highly recommended on the Settings.Controls panel) <ctrl-left click> on the red damage bar just above the range number. A target icon will appear above the ship.
5. ↑ ^{5.0 5.1} The standard main battery firing range or standard detectability range are those values shown in port. They are not changed by in-battle effects such as gun bloom, spotting aircraft, smoke, or weather.
6. ↑ This means:
   • If the submarine gets the warning on the surface, it is in the range of an activated Submarine Surveillance.
   • If the submarine gets the warning at periscope depth, it is in the range of an activated Surveillance Radar.
   • If the submarine gets the warning at maximum depth, it is either in the range of an activated Surveillance Radar or Hydroacoustic Search (but more than 2 km away).
