Weapon and armour proficiency: the wizard is proficient with the club, crossbow (light and heavy), quarterstaff, magic wands and any one martial weapon. He is proficient with light and medium armour.
Spells: A warmage casts arcane spells which are drawn from the warmage spell list. A warmage must choose and prepare her spells ahead of time (see below).
To learn, prepare, or cast a spell, the warmage must have an Intelligence score equal to at least 10 + the spell level and a class level of twice the spell level-1. The Difficulty Class for a saving throw against a warmage’s spell is 10+the spell level+half the warmage's class level+the warmage’s Intelligence modifier.
Like other spellcasters, a warmage only has a limited amount of mana a day. A warmage must prepare their spells in advance, spending the mana when they prepare the spell and then noting down that the spell is memorized. A warmage can only cast a meorized warmage spell.
Unlike a bard or sorcerer, a warmage may know any number of spells. She must choose and prepare her spells ahead of time by getting a good night’s sleep and spending 1 hour studying her spellbook. While studying, the warmage decides which spells to prepare.
Armoured mage: a warmage learns to cast spells in armour. at 1st level a warmage gains the ability to ignore arcane spell faliure for warmage spells when they are in armour they are proficient with.
Direct damage specialization: a warmage deals +2 damage with spells that deal lethal damage.
Bonus feats: at 5th level and every 5 levels thereafter the warmage gains a free metamagic or item creation feat.
