This spell enables the caster or the creature touched to move and attack normally for the duration of the spell, even under the influence of magic that usually impedes movement.
The spell also allows a character to move and attack normally while underwater, even with slashing and bludgeoning weapons, provided that the weapon is wielded in the hand rather than hurled. The freedom of movement spell does not, however, allow water breathing.
