At 13th level, it functions as a +3 longsword. A force sword cannot be attacked or harmed by physical attacks, but dispel magic, disintegrate, a sphere of annihilation, or a rod of cancellation affects it.
If a creature you attack with the sword has spell resistance, you must attempt a caster level check (1d20 + your caster level) against that spell resistance the first time the force sword strikes it. If you fail the check, the spell is dispelled. If you succeed, the weapon has its normal full effect on that creature for the duration of the spell.
