Tis' the joy of NP Looping.

When unleashing a Noble Phantasm, all NP Gauge is consumed at the beginning of the Servant’s chant. However, after the Noble Phantasm deals damage, depending on the Servant and the conditions, some NP Gauge is refunded after using the NP.

With a sufficiently high NP refund, it becomes possible to spam NPs almost endlessly.

Use this FGO Calculator to find out the amount of NP refund provided by a Servant’s NP alone. Critical Stars generated and NP Damage are available as tooltip, or as a Chart toggle.

Use the advanced features below to adjust for specific combat setup and save it for future reference.
