Im at Kraya and i can beat her sort of easily in the first part of the battle until she pulls out the 3 sabers what is a good strategy here.

using all stims and enlightenment and force immunity to do this btw

I'd suggest hit and run. The pathing AI in the game isn't the greatest, so if you make tracks fast enough you can zip around a pillar and have some breathing time before the floating sabers catch up with you. Most people use this opportunity to spam Force Storm or some other offensive power to take down the sabers.

Using force wave will actually stun one of the sabers and take hit points away from the other two even though they avoid being stunned. Hit master speed if you have it then hit master flurry, take one saber at a time and you shouldn't have any problems.
