The Warding focused arcane school complements the Eldritch Warder multiclass archetype.
Associated School: Abjuration.
Replacement Powers: The following school powers replace the resistance and energy absorption powers of the abjuration school.
Arcane Defense (Ex): At 1st level, you select a single wizard school. You gain a +1 bonus on saving throws against arcane spells of that school. Every four levels beyond 1st level you select a new school and gain this bonus against arcane spells of that school (to a maximum of five schools of magic at 19th level). Furthermore, each time you select a new school, the bonuses for the schools you have already chosen increase by 1. At 20th level, you become immune to the effects of the school of arcane magic you selected at 1st level. Neither harmful nor helpful arcane spells of that school have an effect on you. If a spell of that school is an area of effect spell, the spell goes off as normal, but you are untouched by its effects.
Suppression Ward (Su): At 6th level, as an immediate action, you can surrounds yourself in a shimmering aura of suppressive magic for a number of rounds per day equal to you level. This aura excludes all spell effects of your caster level or lower. The area or effect of any such spells fails to affect you while the aura is activated. Excluded effects include spell-like abilities and spells or spell-like effects from items. However, this aura does not affect your ability to cast spells, and such spells take affect as normal. Spells cast by a spellcaster with a higher caster level than you are not affected by the aura, nor are spells already in effect when the aura is activated. Note that spell effects are not disrupted unless their effects enter the aura, and even then they are merely suppressed, not dispelled. If a given spell has more than one level depending on which character class is casting it, use the level appropriate to the caster to determine whether an aura of suppression stops it. These rounds need not be consecutive.
