Primary Fire: Throws one Grenade.
Second Fire: Throws two Grenades that arc to the sides. More mana usage and slower fire rate.
Tips: When using secondary fire remember that you will throw the grenades slightly to the sides. As such ether use them when a group of enemys are in front of you, or force them to blow up early so they dont move apart from each other even more. Since they fire off to the sides, if an enemy is directly in front of you, they will not hit it.
