The reason why your friend took 30dmg because you missed him. The laser dagger hit next to him. When he threw it at you, he hit you right in the belly. As from what I know the laser dagger (when thrown) has a small AoE DMG so if you miss just by a little it will do reduced dmg but if you hit it will do a tone.
