This spell, favored among eladrins visiting the Material Plane, envelops the target in a protective, shimmering aura of light. The luminous armor resembles a suit of dazzling full plate, but it is weightless and does not restrict the target's movement or mobility in any way. In addition to imparting the benefits of a breastplate (+5 armor bonus to AC), the luminous armor has no maximum Dexterity restriction, no armor check penalty, and no chance for arcane spell failure.
Luminous armor sheds light equivalent to a daylight spell and counters darkness spells of 2nd level or lower with which it comes into contact. In addition, the armor's brightness causes opponents to take a -4 to penalty on melee attacks made against the target. This penalty stacks with the attack penalty suffered by creatures sensitive to bright light (such as dark elves).
Sacrifice: 1d2 points of Strength damage.
