Improve Armor (3.5e Spell)
From D&D Wiki
|Level:||Duskblade 1 (Redux)|
|Casting time:||1 Standard Action|
|Spell Resistance:||Yes (Harmless)|
Improve Armor magically enhances the armor a spellcaster is wearing. This effectively grants a +2 enhancement bonus to the armor (but not the shield) the caster is wearing when the spell is cast. This enhancement bonus increases by +1 for every three caster levels above 3rd, to a maximum of +5 at caster level 12th.
This enhancement bonus stacks with the armor's armor bonus, but not with other enhancement bonuses from other magical effects, or from magically enchanted armor. While this spell can affect clothing, it can not be used if the caster is naked.
