Once in combat, and a certain type of ammo. Serah's blade is Energy for example, since it's made of Plasma. Magus' shocks were counted as something else too, but I forgot what.

The current main enemy we're facing is immune to Kinetic weapons.

Ohh, alright. I got it. Should have known that Cruxi can't be killed by mere bullets.
