My final versions of the Eyros prestige classes for half-orc nobles, now appropriately balanced:
Dragonclaw Duelist (Eyros Prestige Class)
Experienced students in the Claws of the Dragon martial art develop some distinctive techniques with their noble weapon, the two-bladed sword. Those students who dedicate themselves to the training and earn some favor from their master teacher will acquire this prestige class, learning how to duel skillfully in the traditional Eyros style. Since the masters only teach half-orc nobles of Eyros, these students often train their courtly skills at the same time, in addition to traditional Eyrian military disciplines and duties. The Claws of the Dragon martial art emphasizes use of the two-bladed sword, especially for charging and other offensive maneuvers, intended to cut down an opponent quickly and spectacularly.
Prerequisites: Eyrian only, half-orc only, Base Attack Bonus +3 or higher, Bluff or Intimidate 5+ ranks, Jump 7+ ranks, Knowledge (war) 2+ ranks, Exotic Weapon Proficiency (Two-Bladed Sword), Two-Weapon Fighting, Weapon Focus (Two-Bladed Sword), must be formally trained in the Claws of the Dragon martial art by a recognized master in Eyros.
Alignment: Any.
Hit Dice: d8.
Class Skills: Bluff, Diplomacy, Escape Artist, Handle Animal, Intimidate, Jump, Knowledge (history), Knowledge (war), Perform, Ride, Sense Motive, and Tumble.
Skill Points at Each Level: 4 + Intelligence modifier.
Weapon and Armor Proficiency: This prestige class grants no additional proficiencies.
Fury of the Dragon: A Dragonclaw Duelist can make two attacks against an opponent they are charging, but only when using a two-bladed sword and jumping at least 3 feet high before the strike. In these circumstances, the Dragonclaw Duelist attacks once normally with their primary had, with the usual charging bonus, but also gains an off-hand attack against the same opponent or any other foe within melee reach, immediately after the primary-hand attack. The off-hand attack does not gain a bonus for charging, and instead suffers a -2 penalty to the attack roll. Do not apply the normal two-weapon fighting penalties with this special charge attack. Also, when using Fury of the Dragon, the Dragonclaw Duelist's AC penalty for charging is worsened by 1 point, for as long as they suffer that charging penalty to AC.
Dragon's Dive (Ex): The Dragonclaw Duelist is skilled at leaping into the air to bear down on their foe with a whirling two-bladed sword, like a dragon on the dive. Dragonclaw Duelists of the Dragon add their level in this prestige class, as a competence bonus, to both their Jump checks and the total maximum height and distance they can jump, in feet. If the Dragonclaw Duelist jumps high enough for at least their knees to be level with an opponent's chest, they get a +1 circumstance bonus on the attack roll for effectively having the high ground. A Dragonclaw Duelist may jump as part of a move, double-move, charge, or partial charge. Dragon's Dive is an extraordinary ability.
Defense of the Dragon: A 2nd-level Dragonclaw Duelist gains Two-Weapon Defense as a bonus feat. If they already possessed the feat, instead double the shield bonus of Two-Weapon Defense.
Wiles of the Dragon: When a Dragonclaw Duelist wields a two-bladed sword, they can use the Bluff skill to feint in combat as a move-equivalent action instead of a standard action. When they successfully use the Bluff skill to feint in combat, the Dragonclaw Duelist deals +1 damage with the following attack if striking with a two-bladed sword. This bonus damage is multiplied normally in the event of a critical hit. Wiles of the Dragon is gained at 3rd-level in the Dragonclaw Duelist prestige class.
Strength of the Dragon: The training and determination of the Dragonclaw Duelist pays off in part when they reach 4th-level in the prestige class, as they learn to apply the full force of their strength with the two-bladed sword. Henceforth, whenever they attack with both ends of a two-bladed sword on their action, they treat each end of the two-bladed sword as a one-handed weapon for purposes of damage. The off-hand end still counts as light for purposes of attacking, but deals damage as though it were instead a one-handed primary weapon. Thus, they apply their full Strength bonus to damage with the off-hand as well as with the primary-hand, while feats and abilities likewise treat the off-hand end as a one-handed weapon for damage, such as for Power Attack if they have that feat.
Fangs of the Dragon: At 5th-level in this prestige class, the Dragonclaw Duelist has attained such a level of skill with the two-bladed sword that it strikes as an extension of their own arms. With a two-bladed sword, the attack penalty for fighting with a double weapon is reduced by 2 points. This does not affect Fury of the Dragon, since that ability does not use the normal two-weapon fighting penalties.

Dragonclaw Master (Eyros Prestige Class)
Students who rise to any master rank in the Claws of the Dragon martial art tradition may begin to study the deeper meanings and uses of the art. They learn how to apply this style to mass combat situations and taking on large groups of enemies, fighting like a rampant dragon tearing through hordes of enemies. Although they may train less in defense and physical might, the advanced students gain significant offensive prowess from their mastery in Claws of the Dragon philosophy. These masters of the fighting art also work on developing more draconic cunning and awareness, learning to apply tactics and strategies more quickly and broadly. Taking this prestige class is a step in that direction, leading towards mastery in the Claws of the Dragon style. Dragonclaw Masters are not only exceptional duelists, but also master tacticians and main battle troops, making excellent centurions and legates in the Legions of Eyros. They can frighten lesser troops into surrender or retreat, and cleave through numerous foes with deadly accuracy when they foolishly offer resistance against the superior Dragonclaw Master.
Prerequisites: Eyrian only, half-orc only, Base Attack Bonus +7 or higher, Bluff or Intimidate 10+ ranks, Jump 10+ ranks, Knowledge (war) 5+ ranks, Tumble 5+ ranks, Exotic Weapon Proficiency (Two-Bladed Sword), Improved Critical (Two-Bladed Sword), Power Attack, Two-Weapon Fighting, Weapon Focus (Two-Bladed Sword), Wiles of the Dragon class ability, must be formally trained in the Claws of the Dragon martial art by a recognized master in Eyros.
Alignment: Any.
Hit Dice: d6.
Class Skills: Bluff, Diplomacy, Escape Artist, Handle Animal, Intimidate, Jump, Knowledge (history), Knowledge (war), Perform, Ride, Sense Motive, and Tumble.
Skill Points at Each Level: 4 + Intelligence modifier.
Weapon and Armor Proficiency: This prestige class grants no additional proficiencies.
Lunge of the Dragon: When the Dragonclaw Master charges an opponent, he or she can move both before and after the charge, rather than halting once he reaches the foe. He or she is still limited in how far they can move, as normal for a charge, and they must still move in only a straight line, also as normal for a charge. The Dragonclaw Master's movement with this charge does not provoke attacks of opportunity from any opponents they charge. Additionally, the Dragonclaw Master's charge penalty to Armor Class is reduced by 1 point. Lunge of the Dragon only functions when using a two-bladed sword.
Uncanny Dodge (Ex): A 1st-level or higher Dragonclaw Master retains their Dexterity bonus to AC even when surprised or flat-footed, though he or she does not retain any other AC bonuses that rely on keeping the Dexterity bonus to AC. Further, once they reach 2nd-level in the prestige class, they can no longer be flanked, and thus a Rogue cannot Sneak Attack them merely by flanking. However, a Rogue with at least 4 character levels more than the Dragonclaw Master may still flank him or her, and may then use Sneak Attack against them normally. Uncanny Dodge is an extraordinary ability.
Rampage of the Dragon: Dragonclaw Masters receive the Whirlwind Attack feat for free at 2nd-level, as a bonus feat, and do not need to meet the feat's normal prerequisites.
Wings of the Dragon: By 3rd-level in the Dragonclaw Master prestige class, the character has improved their skill at leaping attacks to be truly devastating. They gain +2 on Jump checks, and on damage rolls with any attack they make with a two-bladed sword while jumping at least 5 feet high. The damage bonus is multiplied normally in the event of a critical hit. Lastly, if a Dragonclaw Master jumps at least half as many feet high as their opponent's current height, just before attacking the foe with a two-bladed sword, the Dragonclaw Master receives a free trip attempt against their opponent, using the two-bladed sword. If they fail this trip attempt, the opponent does not get a chance to trip the Dragonclaw Master, but if the Dragonclaw Master successfully trips the opponent, it occurs just before the attack. This trip attempt does not provoke attacks of opportunity from the opponent being tripped.
Voice of the Dragon (Ex): A Dragonclaw Master gains +2 on both Diplomacy checks and Intimidate checks, at 4th-level in this prestige class. When demoralizing foes with the Intimidate skill, the Dragonclaw Master panics them instead, causing the demoralized foes to flee in fear of the Dragonclaw Master in addition to the effects of being shaken. Also, the panicked foes suffer a 50% chance of dropping anything they hold, just before fleeing. Voice of the Dragon is an extraordinary ability.
Mastery of the Dragon: The threat range of any two-bladed sword, when wielded by a 5th-level Dragonclaw Master, is improved by 1 point. This stacks with any other threat range adjustments, and is factored in last. In addition, the Dragonclaw Master treats opponents as having one degree less cover when he or she attacks them with the two-bladed sword. This particular benefit does not reduce total cover, however.
