Metroid Prime Hunters/Spire

General Info
His affinity weapon is the magmaul and his alt-form is the dialanche. Spire is at home in lava arenas. He can stand in lava and not be damaged, as opposed to other Hunters who constantly get burn as they stand in the stuff. The magmaul throws like a grenade and if it hits an enemy and is charged, it sets him/her on fire, draining his/her energy. Shots from the Magmaul do bounce around, although not as much as the Judicator. The magmaul does backfire often, especially if you are running and shooting at the same time. The dialanche is a big rock form, not too complex to control, that actually attacks enemies directly as opposed to using bombs. His Alt-Form can scale walls, a great thing to have in some arenas. This is useful if you and your enemy are too close for comfort. Spire is the biggest & slowest hunter in the game, which may be a weak point.

Strategy

 * Spire resistance to lava makes him the #1 choice for any arenas with excessive lava.
 * Spire's alt form, Dialanche can climb up walls, making it ideal for reaching high up places, out of reach by other hunters. Such places include high up ledges in the arena, Council Chamber. These ledges are great sniping spots and provide a great view of the arena. However when climbing be aware, you are a very easy target whilst climbing. Try to make sure you have cover when climbing, and that you checked the coast was clear before attempting to climb. Don't get reckless, the Dialanche isn't fast enough when climbing, or when rolling to take a massive amount of damage and then to attempt to get health. One of the most likely times you'll be assaulted is when you climb.
 * The Magmaul when charged sets a foe aflame. While the burn is draining their health add in a few more shots from the Magmaul for good measure. This works escpecially well when equipped with the Double Damage. If your opponent has 99 energy or below they will quickly be killed. The initial shot takes off most of their energy, while the burn takes care of whatever energy remains. (The Double Damaged Charged Magmaul deals just about 90 damage. The burn does 4 damage every 0.5 seconds  so anyone with less than 120 health will almost be guranteed to die)
 * Dialanche is one of most effective alt-forms. His swipe attack can take off chunks of energy from enemy hunters and can repel other alt-forms, so if you are at home with close-quarters combat, Dialanche is the alt-form for you. But be careful with it, for it is very slow.
 * You should probably run for health if you get to about 100 or less health, with how slow Spire is. A good way to get people off your tail is to simply burn them, while running backwards.
