Nice Wiz, definitely a post that needs some attention.
Obviously as the school of war the Warlock in my opinion should really have some teeth to his attacks:
Unleash Hell (Yes, from Gladiator): Conjuration Nonliving 0-0
Level 4 Mana 20
Armor 5 Health 14
1-3 Ranged Fire Damage 6 Dice D12 6-10 1 burn, 11+ 2 burn
Warlord only, Legendary
A stationary War Machine that reigns fire balls from great distances. Basically the Wizard Tower without being able to change spell, but the bonus of having to pay mana only once. High mana for obvious reasons. Thoughts?
