Os Celaes, the Orc Hunters

Et forslag til en prestige class i Lagos.
Ideen er at Os Celaes består af elvere der vil have grønhuderne og andet skravl ud af lagos.
De er bygget over Darkwood Stalker fra Complete Warrior. De er racister så det batter, men det er vel også iorden at slå orker ihjel...?

Weapon and Armor Proficiencey: Os Celaes gains no further proficiency with armor or weapons
Ancient Foe (Ex): Due to his extensive study of orcs and training in the proper techniques for combating them, an Os Celaes gains a +2 bonus on Bluff, Listen, Sense Motive, Spot, and Search checks when using these skills against orcs. He gets the same bonus on weapon damage rolls against these creatures. An Os Celaes also gets the bonus on damage with ranged weapons, but only against targets within 30 feet. The bonus on damager dos not apply to creatures immune to critical hits. At 4th, 7th and 10th level the Os Celaes’ bonus goes up by +2. This bonus stacks with a favored enemy bonus (if any) aquired through ranger levels.
Hunter’s Oath: At 1st level the Os Celaes takes an oath to stay true and follow the cause no matter what stands in the way. As the Os Celaes progresses in level, so does his blind faith in the oath. In gaming terms this means that the Os Celaes gains a +1 bonus on any will save that is forced upon him by orcs (spells and effects). This bonus is raised by one for every level of Os Celaes.
Uncanny Dodge (Ex): Starting at 2nd level, an Os Celaes gains this ability. If he already has the uncanny dodge ability from another class, the character gains the improved uncanny dodge instead.
Sneak Attack (Ex): If an Os Celaes has this ability from another class, the bonuses stack. Same as Rogue.
Darkvision (Ex): Although stealthy and keen-eyed, the Os Celaes is often at a disadvantage against orcs when fighting in darkness. As they grow in experience, their night vision improves, eventually matching the darkvision of their hated foes.
Improved Uncanny Dodge (Ex): At 5th level and higher an Os Celaes can no longer be flanked. Same as Rogue.
Dodge Critical (Ex): Although often more skilled than their foes, Os Celaes have seen too many battles won by one lucky blow from a falchion. At 8th level, an Os Celaes becomes able to turn even the luckiest blow into a grazing strike. Once per day an Os Celaes can make a Reflex save (DC 20 + the enhancement bonus, if any, possessed by the weapon) to turn a critical hit dealt upon him into a normal hit. The Os Celaes must be aware of the attack, and not flat.footed, and he must declare his attempt to reduce the effect of the critical hit before the damage is dealt.
Death Attack (Ex): If a 10th level Os Celaes stuies a particular orc for 3 rounds and then makes a sneak attack with a melee weapon that successfully deals damage, the sneak attack has the additional effect of possibly killing the target. While studying the orc, the Os Celaes can undertake any other actions as long as his attention stays focused on the target and the target does not detect the Os Celaes or recognize him as an enemy. If the victim of such an attack fails his Fortitude save (DC 10 + the Os Celaes’ level + The Os Celaes’ Wis modifier), he dies. If the victims saving throw succeeds, the attack is just a normal sneak attack. Once the Os Celaes has completed the 3 rounds of study, he must make the attack within the next 3 rounds.
