Venom Dart IQ12 (M) [3]: This creates a magical dart that is cast at the target. If the dart hits, it inflicts 1d-1 damage. If the dart inflicts damage, the victim must make a 4/ST save or take 1d poison damage for the next 3 rounds.
A target that is already suffering from the poison damage of this spell does not get a HT roll tom resist any subsequent successful attacks.
