Many battlemages focus purely on destructive evocations, but some extend their tactical studies to include use of the tried-and-true protection of steel. These armored battlemages learn to move and cast spells in even the most restrictive armors, and have developed new methods to magically enhance their armor.
An armored battlemage gains this ability at 1st level instead of 7th. When wearing medium or armor, the armored battlemage gains a +4 bonus on concentration checks to cast defensively. This stacks with the bonus from the Combat Casting feat.
This ability replaces spell combat and alters the medium armor ability.
An armored battlemage cannot spend points from his arcane pool to enhance weapons. Instead, he can expend 1 point from his arcane pool as a swift action to grant armor he is wearing a +1 enhancement bonus for 1 minute. For every 4 magus levels he has beyond 1st, the armor gains another +1 enhancement bonus, to a maximum of +5 at 17th level. These bonuses stack with existing armor enhancement bonuses to a maximum of +5.
Multiple uses of this ability do not stack with themselves.
At 5th level, these bonuses can be used to add any of the following armor special abilities: balanced, bitter, fortification (heavy, light, or medium), ghost touch, invulnerability, spell resistance (13, 15, 17, or 19), or spell storing.
Adding these special abilities consumes an amount of bonus equal to the ability’s base price modifier. In addition, the armored battlemage can grant his armor the energy resistance special ability at the cost of a +3 bonus or the improved energy resistance special ability at the cost of a +5 bonus. These special abilities are added to any the armor already has, but duplicates do not stack. If the armor is not magical, at least a +1 enhancement bonus must be added before any other special abilities can be added. These bonuses and special abilities are decided when the arcane pool point is spent and cannot be changed until the next time the armored battlemage uses this ability. These bonuses do not function if the armor is worn by anyone other than the magus.
An armored battlemage can enhance only one suit of armor in this way at one time. If he uses this ability again, the first use immediately ends.
This ability alters arcane pool.
At 8th level, he gains armor training 2.
At 13th level, he gains armor training 3.
At 18th level, he gains armor training 4.
This ability replaces the magus arcana gained at 3rd and 18th levels, and improved spell combat.
An armored battlemage gains this ability at 7th level instead of 13th.
This ability alters heavy armor.
At 14th level, the armored battlemage can grant his armor the glamered special ability at the cost of a +2 bonus, the slick or shadow special ability at the cost of a +3 bonus, and the greater slick or greater shadow special ability at the cost of a +5 bonus when using his arcane pool.
This ability replaces greater spell combat.
