Duskblade:
The duskblade has a d10 as HD.
The duskblade does not gain the Arcane Attunement (sp) ability.
At 15th level, a duskblade gains Armored Mage (ex), he is now able to use heavy armor without incurring a spell penalty.
At 20th level, a Duskblade gains the Empower Blade (sp) ability. Once per day as a standard action, he can imbue his weapon with a tremendous amount of magical might: it becomes a +5 brilliant energy weapon (its type stays the same). Any other magical or material properties of the weapon are suppressed. If the weapon leaves the hands of the Duskblade, it transforms back into its natural state. The weapon remains empowered for one + the Duskblades Intelligence bonus (if any) rounds.
