Powers/Skills/Weaponry: Despite his lack of armor, Anthony is extremely durable. His skin is as tough as iron, and resistant against magic that he casts, and other forms of similar magic. Acid has nearly no effect on him, unless it is an extremely strong kind of acid. Anthony wields an indestructible scythe with around a 1-and-1/2' long handle, And the blade of the scythe comes in after a foot of handle. He can store the scythe in a safe place and summon it to his hands at will at any time. He also has a bow and quiver with an infinite number of arrows. This also has the same summoning and storage ability. His scythe and arrows aren't normal, though. They are extremely sharp and the arrows fly close to 200 mph, and both have the ability to charge to different kinds of magic. Once a magic type has been used, it cannot be re-used for a minute. They are as follows: 

Fire, creates an inferno once landed, envelops a 10 foot radius completely, and tends to be ~1500-2000 degrees Fahrenheit 
Ice, freezes all creatures within a radius of 10 feet for about 15 seconds. Can be combined with Water magic to create a hailstorm, which spans a 20 foot radius, and constantly drops grapefruit sized hail.
Earth, creates a large bog of mud in a 30 foot radius, slowing all who walk through it. Lasts for about a minute. 
Wind, create (Very powerful) random gusts of wind in a 10 foot radius strong enough to knock over a fully grown elephant. Lasts for half a minute. Can be combined with Water magic to create a Windstorm, spanning a 30 foot radius, and sending out winds about half as strong.
Sun, blind all (Excluding Anthony) in a 20 foot radius for 15 second. 
Moon, cause a large hallucination that appears different for each champion. It is of whatever each specific champion fears most. Lasts for half a minute.
Lightning, summon a lightning bolt that hits the nearest champion with ~1 mil. volts of electricity. Can be combined with Water magic to create a thunderstorm, which sends a strike of lightning to the nearest champion (Excluding Anthony) every 10 seconds, striking them with ~.85 mil volts.
Rain, a rainstorm begins in the arena. The storm lasts for a full minute, and constantly drops 50 gallons of water per second in a 50 foot radius.

Added more detail, and more potential. Also, when i say 'radius', i mean the radius from the arrow's landing point.

Basically i nerfed Skallgrim's description a bit, but added three more 'kinds' of magic.
