Each of these talents has varying effects depending on your spec.
Your 1st Talent has various effects:
Balance – "Sunfall:" Entering your Solar Eclipse transforms your Starfall into Sunfall and resets the cooldown.
Feral – "Lunar Inspiration." Moonfire is now usable while in Cat form, adds 1 combo point and costs 30 energy.
Guardian – "Guardian of Elune:" Your Savage Defense now lasts 4 seconds and increases your dodge by 100%.
Restoration – "Moment of Clarity:" Omen of Clarity now lasts 5 seconds, instead of one cast. Sounds pretty nice.
2nd Talent
Balance – "Insect Swarm:" Attack the target with bugs, doing damage every 3 seconds for 15 sec. Each time damage is done you get 5 lunar or solar energy, whichever is more appropriate at the time. Cannot be cast while in Eclipse.
Feral – "Bloody Thrash:" Your Thrash now spreads Rake to other damaged enemies. Awards 1 combo point if it strikes your current target.
Guardian – "Pulverize:" Smash the target using three stacks of Lacerate to deal 500% damage, generate 30 rage, and reduce incoming damage by 20% for 10 seconds.
Restoration – "Germination:" You can apply two rejuvenations to the same target. Tanks and PvP allies will love you.
3rd Talent
Balance – "Equinox:" Your Lunar and Solar Eclipse now last until the other is triggered, instead of ending when you run out of energy.
Feral – "Savagery:" Your Savage Roar is now passive. How does a finishing strike work as a passive? Is the buff always on? Does this add 40% to all physical damage all the time? Is this one going to be the "go to" level 100 feral talent?
Guardian – "Bristling Fur:" this 3 seconds effect, 1 min cooldown, reduces all damage by 50%.
Restoration – "Rampant Growth:" Your Swiftmend now consumes your own Rejuvenation or Regrowth, but has no cooldown.
