>Ignite: Lanches a pea-sized fireball at the target Base Power: 4 Energy cost: 1
>Cool: launches a sphere of Ice at target Base power: 4 Energy cost: 1

Current list of Zombie Types (There is one that Isn't on here... I'll add It when it shows up):
Creeper: Pretty standard.
Spitter: can spit poisonous (or Acidic) saliva from a considerable distance.
Stalker: a quiet, Fast zombie.
Berserker: It's Fast, It's strong, It's tough, and it has an animalistic intelligence. It's also been known to attack other zombies.
Hunter: A Zombie that retains the Knowledge it had in life, but not the personality. Very rare, Very dangerous.
Torch: Only created by necromancers. It is capable of Self Immolation, and fire does not harm it.

What I need:
Weapons/Armor
Figure out how to allocate abilities
Suggestions for new spells/ Zombie types.
