Cost represents how much DP is needed to deploy Operators, summons, and deployable devices.

Operators have different costs depending on their class, branch, and rarity; generally, lower-rarity Operators cost lower DP than higher-rarity ones. Most Operators will have their cost reduced by 1 at Potentials 2 and 6 or at Potentials 2 and 5 for some; welfare Operators have their cost reduced by 1 at Potentals 2, 4, and 6 instead. All Operators have their cost increased by 2 (3 for certain branches) when promoted to Elite 1 as well as another 2 at Elite 2 for some.

An Operator's cost will be increased to 1.5× when they are redeployed for the first time and 2× when redeployed for the second time onwards, but will never be above 99; this is especially noticeable in Challenge Modes that increases the DP cost of certain Operators. Operators return DP equal to half of their current cost when retreated, rounded down, with the following exceptions:

• Charger Vanguards return their base cost when retreated. With the Charger's respective CHG-X Operator Module, their current cost will be returned instead.
• Executor Specialists with their respective EXE-X Operator Module returns 80% of their current cost.
• Merchant Specialists do not return their cost.

Summons and deployable units' cost do not ramp up like Operators do, but will not be returned when they are retreated.

Reductions

Splash Casters' SPC-Y Module reduces their cost by 8.
