You can spend 1 Nova point to make a complexity 2 attack skill roll with a melee weapon against a creature then move up to your speed and make a second complexity 2 attack skill roll with a melee weapon against a different creature, then move up to your speed again and make a third complexity 2 attack skill roll with a melee weapon against a third creature. If one of these Attacks fails, there are no Consequences for failure and you can continue acting.
