Help:Resource Farming

This article aims to provide advice on the better ways to farm the main resources () and consumables ().

As some general rules

• Expeditions are the best way to gain most resources, with the advantage of being AFK compatible,
• Quests are often the better way to farm consumables, especially screws ,
• Sorties generally provide the greatest hourly gain for any resource/consumable, but at the cost of more active playtime and some other resources.

Notes

• Special resources are not detailed here, as they are difficultly "farmable", please refer to each individual page for more details.
• Only repeatable quests are listed on this page, as they are the most relevant in a "farming mindset",
  • One-time quests can also be a major source of resources. Please refer to Quests for more details.
• Expected for screws, monthly expeditions are also omitted here, as even so they reward great amounts of resources and consumables, they are incompatible with a "farming mindset",
• Events and limited-time quests are often a great way to gain all types of consumables, with some events introducing great resource farming spots.
  • Please refer to the current event's page for more details on such addition.

General Tips

Sortie Tips

Resources in sorties are gained from Resource Nodes and Scraping dropped ships.

• Using the lightest possible fleet is recommended to reduce the average sortie costs and so maximize gains.
• For resource nodes, using appropriate gear (//) is essential to maximize gains:

Normal Resource Nodes Gain Modifiers
Equipment / Ship			Bonus Gains (per DLC / Ship)
Type		Name	(& 7-3 O )
	A	Toku Daihatsu Landing Craft Daihatsu Landing Craft Armed Daihatsu DLC + T89 Tank DLC + Panzer II Soukoutei Toku DLC + Ho-Ni Tank	3.0	2.0	0.0
		Ka-Mi Tank Ka-Tsu Tank Ka-Tsu Tank Kai
	B	Drums	2.0	1.5	0.0
	C	Toku DLC + 11th Reg M4A1 DD Toku DLC + Panzer III Toku DLC + Chi-Ha Toku DLC + Chi-Ha Kai Toku DLC + Panzer III J	0.0
All ships			0.0
Resource Cap			N/A
Random Resource Increments			5		0
Notes:

• A battle has to be completed (win or loss) after the resource node in order to claim the resources.
  • Exceptions are resource nodes that are dead-end nodes.

Expedition Tips

Expeditions come in various types and forms, being each more or less suited for some resources or even farming methods.

• Regarding resources:
  • Some expeditions will reward a "modest" amount of resources, but on a short timer, being great on an "hourly gain" perspective, being more suited alongside active gameplay,
  • Some expeditions will reward a "high" amount of resources, but on a long timer, being great on an "absolute gain" perspective, being more suited alongside AFK periods.
• Regarding consumables:
  • Some expeditions will reward a "fixed" consumable, being rewarded 50% of the time,
  • Some expeditions will reward a "GS" consumable, being rewarded with "Great Success" only,
  • Since no expedition rewards more than very few consumables, there is no "long timer" expedition adequate for farming, unless the consumable is a side reward of other resources.
• For most expeditions, having a "Great Success" is advisable, especially for "short timer" ones.
  • This mostly requires sparkling ships, which is time-consuming, but still worth it when trying to reach greater hourly gains,
  • See Success Conditions for more details.

Quest Tips

Quests are mostly used to farm consumables ().

• While it is ideal to use the lightest fleets possible to maximize primary resource gains, it is more important to use fleets that reliably clear the quests.

Landing Craft Carriers

Here is a list of the Landing Equipment / capable ships, used in sorties and expeditions.

Fuel

1-3

Node D is a "normal resource node" rewarding 10~20

• Has many Landing Craft and Amphibious Tanks should be equipped to maximize fuel gain.
  • Drums work as an inferior substitute.
  • Only using those equipment in the fleet is a viable solution.
• When lacking enough Amphibious Tanks for SS(V), Luigi Torelli is recommended as a substitute that can carry Drums.
• When using an AO, the reach rate is 100%, but is only 80% when using an AV instead.
• Once the first battle is complete, "retreat" and "resupply" before going back out.

If done correctly, this can result in an outstanding fuel gain that can surpass expedition gains.

• Using "cheap" ships to refuel in the fleet (such as Kamikaze-class and Mutsuki-class) will optimize the fuel consumption/farming.
• It is alternatively possible to use throwaway DDs with Drums that are never refueled until they are critically damaged, and then scraped to save on resources (do not forget to swap their drums with the new ones before doing this).

Recommended Fleets

• Kamoi/Souya, 4-5DD, 0-1SS(V)
• 1AV/AO, 4-5DD, 0-1SS(V) (if lacking those AO)
• Route = A D B E

1-3 Souya Immortal Farming

Thanks to her incredible Luck (77+) and Armor (62) stats, Souya (AGB) (not AGS nor AGL) can exploit damage mechanics to farm on fuel on 1-3.

• Souya needs to:
  • Be on AGB form (last one),
  • Be max moded, especially her armor,
  • Carry a Large armor
    
    (if possible the one at +10 armor),
    • The armor can be put in a Reinforcement Expansion to save one slot,
  • Be moderately damaged (中破), with 7 HPs,
  • Carry as much Landing Craft
    as possible.

When setup like that, Souya can be sortie alone on 1-3,

• She will follow the route A D B E
• One the battle of Node E, thanks to how damages are calculated in Kancolle, she will be virtually immune to damages and so will survive the battle almost every time,
• Once the battle is completed, the sortie can be ended to gather the fuel and restart a run,
• It is possible to farm about 900+ fuel/h "risk free" using this method.

Note

• The method only works on 1-3 Node E, other battles being able to damage Souya.

7-4

7-4 is a great "risck free" place to farm both fuel and bauxite.

• See the relevant page for more details.

4-3

This map can be used to farm both fuel and bauxite. The fleet used is the same for both resources. Fuel is obtained from node B. Take note that you do not have to retreat if heavily damaged at G. This is because node J is a dead-end node and will end the sortie. Unlike 1-3, a majority of the fleet needs to be combat focused. While this means you cannot bring as many bonus equipment, the base resource gain is higher. This map will cost more buckets compared to 1-3. You should take the AV over Hayasui because of the latter's cost.

Resource Gain

• 30-90 (5 increments}}
  • +2 per
  • +3 per

Recommended Fleets

• 1AV/AO 1CL 2DD 2CLT

Equipment Setups

Ship Type	Equipment	Notes
DD		Because of the limited space for bonus equipment, you do not have the luxury of bringing drums.
CL		This setup is for Abukuma Kai Ni or Yura Kai Ni. These two are the ideal girls for farming this map as the opening torpedoes are great at taking out threats.
		In the event that you are unable to use Abukuma or Yura in this map, simply give your CL a standard artillery spotting setup.
CLT		The midget submarine will allow them to take out some threats early and minimize the damage your fleet takes. OASW is highly recommended, especially since you will encounter submarines enroute.
AO/AV		This setup is for Hayasui. Her slots may be a bit small for the enemies present in this map but they're still enough to take out the weaker enemies. Kamoi is not recommended for this map.
		The AV should have a midget sub to add to the strength of the opening torpedo. The extra seaplane bombers add the airstrike cherry on top.

Ammunitions

3-2

The main method to farm this map is to send one sacrificial DD equipped with a Repair Team and some drums. Simply continue after the battle at node A to reach node B. The repair team will not be consumed. After the sortie, simply move the equipment to a new DD and sortie again. Because you are using a fresh DD each time, this map can be run consecutively. Do note that this method will tank your sortie win ratio. You will need to watch that ratio to ensure you maintain the 75% win rate needed for event participation.

The second method is to send a fleet of 3-6SSV. This method brings a greater return but carries a higher risk and has steeper requirements. SSV can only carry Type 2 Ka-Mi Tanks. This equipment is difficult to obtain and carries a steep cost. Furthermore, there are only 4 non-event SSV. The enemy fleet also contains 1-2 ASW DD that can cost you buckets. All this translates into 18-36 more ammo per run.

DD		The Repair Team/Goddess is to allow your DD to bypass the auto-retreat mechanic for damaged flagships. The drums are to eke out the extra resources.
SSV		Just stack Ka-Mi tanks to maximize resource gains. For 3-slot submarines like I-13 and I-14, just give them an additional tank.

Steel

1-4

There really isn't a good place to farm steel but this is the only map where it is possible to do it at a low cost. This map has random branching which means you are not guaranteed to hit the steel node. The bright side is that you can gain or instead. What you want to do is maximize the power of your opening strike to minimize the damage your DDs will take. Since a majority of the enemies encountered have weak ASW and are forced to target submarines, taking one along can allow you to sub-tank the map. You will want to retreat in the battle after the resource node.

Resource Gain

Equipment Setups

Ship Type	Equipment	Notes
DD		Ideally you should be using landing craft capable destroyers to supplement the meager resource returns.
		This setup is when you are not using Landing Craft-capable destroyers.
CVL		This setup maximizes the CVL's airstrike capability and takes AS+ against the enemy CVLs. If using 2CVL, the other one can swap a fighter for a Type 2 Recon Aircraft to maximize airstrike damage.
SSV		Just stack Ka-Mi tanks to maximize your resource gains if you can manage it. For 3-slot submarines like I-13 and I-14, just give them an additional tank.
		If you lack tanks, you can just equip torpedoes on your SSV. Ideally, she should have the 61cm Triple (Oxygen) Torpedo Mount to maximize her armor.
AV		The AV is meant to be a CVL-lite with opening torpedo capability. It is not recommended to use AV that cannot perform an opening torpedo strike.

Scraping unwanted drops is an excellent source of .

• Larger ships will provide more steel when scrapped.
• Remember that any equiped gear will also be scraped in the process, adding some resources, unless the "unequip" switch is toggled.

Bauxite

2-2

This is by far the easiest map to farm bauxite. The fleet requirements are light and there is only one battle. As an added bonus, it can be run at low morale because you're depending on the airstrike to kill everything. It also has 2 transports to finish your dailies and weeklies.

Node A is a "special resource node" rewarding 1 .

• Using 4 Landing Craft and/or Amphibious Tanks give a 50% chance of rewarding 2 .
• Using more than 4 will not increase this rate.

Farming this map can prove a bit frustrating because of the random routing at node C.

• It is recommended to farm for DevMats too, as they are rewarded on the off-route path (see below).
• It is additionally recommended to bring 1 Surface Surface Radar on each girl to diminish the resource losses on the storm maelstrom.

Recommended Fleets

• 3CV, 2-3CA(V)/CL/SS(V), 0-1DD
• Route = B C F A
  • 50% chance to route to A, 50% to G

CV		At least 144 fighter power is needed for AS+ on node F. When enough fighters are used to reach this value, the other planes can be bombers to maximize damage. It is recommended to use carriers with at least "medium range", so that their attack takes priority over the other ships. See Range for more details. The Radar can be used to block the largest slot and limit bauxite losses.
SS(V)		When using a SS, it should either use torpedoes to maximize damage, or to bring additional buckets.

The fleet used is similar to the leveling fleet with an AV taking the place of the BB/CA. The AV guarantees routing to node E and you can either retreat after node D or continue on to node H to finish daily/weekly quests.

Recommended Fleets

• 2CV/L 1AV 1CL/T 2DD

Equipment Setups

Ship Type	Equipment	Notes
DD		Fairly standard setup for DDs. They won't be contributing much to the battle beyond providing AA support. They are primarily here to reduce costs. Else, putting more CL and CA in the fleet would still work.
CL		Setup for CLs that are capable of Artillery Spotting. For those that are not, simply replace the seaplane with a radar or anti-air gun.
CLT		CLTs are useful at increasing the pass rate for this map. The addition of a midget sub for opening torpedo strikes can reduce the number of threats even further.
CV/L		You may need to shuffle around some planes in order to hit the 162 fighter power required for AS+. One of your carriers should also have a Saiun if you can manage it.
AV		You should be using an AV capable of opening torpedo strikes. One midget sub and two torpedoes will provide sufficient power for the opening torpedo strike to take out some of the tougher enemies on this map.

Nodes G H are "Air Reconnaissance", a unique kind of node, rewarding , , and .

• Bringing Large Flying Boats
  and Seaplanes (SPR and SPB) will increase the chance of getting more resources/materials.

While this map has the potential to return significantly more DevMats than 2-4, it is also costlier and more difficult. The enemies encountered are strong and any node has the potential to force a retreat. Furthermore, to claim the resources, the boss has to be at least B ranked. This can be a tall order when fighting BB, CA, and DD Hime with a light fleet.

Recommended Fleets

DD		Because this map has no air power, the guns can be whatever is best on each DD. The wildcard can be anything that does not interfere with the double attack setup, usually a Radar. This setup can alternatively be swapped with other Night Cut-In setup if available.
		It is advisable to have 1-2 DD on OASW duty, preventing some retreats.
CL	Minisub//	The CL can play most roles, being a crucial component to defeat the boss. It should therefore be focused for combat/night battle, carrying additional geras if possible (especially true for 4 slots CL).
AV	Bomber//Minisub	Akitsushima and Nisshin are the only LFB capable AV, and so should preferably carry as many planes as possible to maximize gains. Other AV are still viable, with the ability to carry either more Bomber or one Minisub. Recon can be used but are a waste of potential.
