Jedi could not effectively block a phaser though. unlike blaster bolts in SW, the phaser can be fired continually, so its like a water hose only of energy. There's no way to block it with a lightsaber. A Jedi would have to be jumping all over the place in order to not get killed by a phaser. There's just no way they would be able to stop it with a saber because its a continuous stream, not a blot. However, If you just held a saber up and started shooting at it with a phaser at full setting I doubt it'd do much, the lightsaber would prolly stop it. Unfortunately that wouldn't work in a real fight cause all you'd have to do is move the phaser around and they Jedi couldn't stop it with the saber.
