Whirlwind rage (Ex): A Storm rager learns to channel her Rage abilityin order to improve her speed and reflexes.
The Storm rager’s morale bonus to saving throws now applies to Reflex saves as well, and her morale bonus to ability scores is also applied to dexterity.
Finally, she is always under the effect or Guarded stance and Rolling dodge when raging and does not take the usual AC penalty induced by rage.
Storm warrior: At 2nd level, Storm rager levels stack with Barbarian levels for purposes of choosing new rage powers and their effect. Furthermore, the Rager gains 2 extra rounds of daily rage use per class level.
***
Uncanny Dodge (Ex): A Storm rager can to react to danger before her senses would normally allow her to do so. She cannot be caught flat-footed, even if the attacker is invisible. She still loses her Dexterity bonus to AC if immobilized. A Rager with this ability can still lose her Dexterity bonus to AC if an opponent successfully uses the feint action against her.
If a Storm rager already has uncanny dodge from a different class, she automatically gains improved uncanny dodge (see below) instead.
***
Improved Uncanny Dodge (Ex): At 3rd level and higher, a Storm rager can no longer be flanked. This defense denies a rogue the ability to sneak attack the Storm rager by flanking her, unless the attacker has at least four more rogue levels than the target has Barbarian levels.
***
Evasion (Ex): At 4th level, the Storm rager takes no damage on a successful Reflex saving throw against attacks. If she already has evasion from another source, she gains Improved evasion instead (see below).
***
Speed of Thunder (Su): At 5th level, the Storm rager gains a permanent 5ft untyped increase to her base speed, and another extra 10 feet while raging (for a total increase of 15ft while raging).
***
Greater Whirlwind rage (Ex): At 6th level, the Storm rager can make an extra attack per round, but then takes a -2 penalty to all her attacks until her next turn.
***
Lightning strikes (Ex): At 7th level, the Storm rager can use her Unexpected Strike rage powers a total number of times per rage equal to her unmodified dexterity bonus.
***
Improved Evasion (Ex): At 8th level, the Storm rager learns improved evasion. She henceforth takes only half damage on a failed reflex save. A helpless Storm rager does not gain the benefit of improved evasion.
***
Thundering weapon (Su): At 9th level, any weapon held by the Storm rager deals an extra d6 sonic damage per hit, and upon scoring a critical hit deals 1d10 (2d10 if the weapon multiplier is x3, etc) and forces his target to succeed a fortitude saving throw (DC 10+1/2 Class levels + The Rager’s Con modifier) or be permanently deafened.
***
Storm rage (Su): At 10th level, the Storm rager earns her name. When raging, a lightning nimbus envelops her, granting her 10% concealment and dealing 1d6 electricity damage to any creature landing a hit within her reach.
*bump* balanced?
the only 2 things i would like to point out is that all of the prestige classes require a minimum level of 5 in pathfinder and yours requires level 8
i would drop the base attack to +5 and the skill rank to 5.
