This item can resupply fuel and ammunition at sea during combat. With this equipped during sorties when fuel and ammunition have become used up, the "Underway Replenishment" will occur and resources will be resupplied on the spot. Please use it to support the long sorties of the decisive battle.
(will disappear once activated and used)
Single-use consumable item.
Can be purchased off the cash shop with 300 DMM points for 2.
Allows to resupply fleet's fuel and ammo during a sortie before entering the boss node (fuel and ammo are known to affect evasion and damage, respectively). Before entering the boss node you will be asked if the item(s) should be used (許可 or 却下, choosing 許可 will consume the item(s)).
For normal fleet, replenishes 25% (rounded down) of fuel and ammo of all ships, 50% when two items are used. For combined fleet, replenishes 15% of fuel and ammo of all ships (both main and escort fleets), 30% for two items.
Used fuel and ammo will be detracted from your stockpile. Partial replenishment can occur when not having enough fuel/ammo, with 0 fuel/ammo the choice for replenishment won't appear. Married ships won't receive the usual 15% reduction for fuel/ammo consumption.
Can always be activated, regardless of Fleet Oiler fleet position, morale, or health, except when she is retreated using Fleet Command Facility.
