As the swords contact the clone pressed forward with his sword and punched himself as fast/strong as he could. The result would be the lightning clone reverting to its natural lightning-state, at the same time electrocuting whatever it is touching which be Katrina's sword in result electrocuting her. Jet made sure not to put to much lightning Chakra into the lightning clone however it still probably will paralyses a normal person for a few minutes and for Katrina possibly for a few seconds but that's all Jet needs. Then real Jet quickly throws two ninja stars at Katrina's shoulders might to cut them on the sides slightly and fly past. If this hits she get more shocked because he put some lightning Chakra into them. Jet also noted Katrina needs to speak for some of her magic.
Katrina, having already uttered the spell, was only slightly shocked, as the ground absorbed at least half of the lightning. Since Jet had been holding back with the chakra, it wouldn't be enough to paralyze her, though she felt the painful, numbing sting. It made her arm seem like it was moving through mud, and it would stay that way for a few more moments while her healing factor mended the limb. She cast out the residual lightning, sword point aimed at Jet, and also added her own energy to the spell, saying, "Kveykva eitha!"
Katrina turned to the side as a bolt of silver-blue energy danced from Uden's black tip, moving faster than human eyes could follow. Because of her turn, both shuriken would narrowly miss. If it hit him, he would be the one to be paralyzed instead. Regardless of if the bolt landed or not, Katrina leaped into the branches of the tree with a single jump.
