GRD, Chain Shift and EXS
The combat system rewards smart decisions around the GRD gauge. With Chain Shift, you convert collected GRD into EXS and can cancel certain actions to chain further attacks. Together with the EXS techniques, this creates longer combinations and tactical decisions about when to spend resources.

Creeping Edge and Celestial Vorpal
Creeping Edge and Celestial Vorpal expand your tactical options. The new systems affect the interplay of defence, movement and attack. Existing characters have also received additional special techniques, including Hyde and Linne.
