Suitable CE choice if you wish to increase the NP acquisition rate solely without any other effects.
Increase NP Gain by 25%
Increase NP Gain by 30%
How to use
This CE increases your NP gain when attacking by 25%, which is slightly better choice if you want to increase your NP building rate only without trying to boost your damage with Arts cards performance increase CE. However, it does have its disadvantage of not being able to provide any additional effects which a CE that increases Arts card effectiveness could provide, besides being somewhat unreliable when used by servants that do not have much offensive power.
Servants that are suitable to equip this CE are mainly those supporting servants that wish to accelerate their NP rotation after use.
