Make your way to the Wailing Caverns.
From the outside of the entrance/cave, it looks like a skull. Fly, or make your way, into the left 'eye' and speak to [npc=116781].
Turn in A Call from the caverns and accept Wailing Critters.
Speak to [npc=116781] again and she will transport you into the Wailing Caverns.
You now start to run a gauntlet of pet battles to reach The Budding Everliving Spore. There are a total of 11 fights in all.
1. [npc=116786] - level 25 beast
In this fight, I faced 2 beasts and 1 flying. All level 25, but no special ablities.
I used 3 mechanical pets; a [npc=48609], a [npc=55356] and an [npc=77221].
My Clockwork Gnome soloed the fight using Metal Fist, Repair and Build Turret, using a repair in the middle of the fight.
2. [npc=116788] - level 25 aquatic
In this fight, I faced 2 Aquatic and 1 flying. All level 25, but no special abilities.
I used 3 flying pets; 2 [npc=67443] and a [npc=62900].
My first [npc=67443] only just soloed the fight, but very easy with 3 pets.
3. [npc=116787] - level 25 flying
In this fight, I faced 2 flying and 1 Aquatic. All level 25, but no special abilities.
I used 3 magic pets; a [npc=38374], a [npc=68660] and a [npc=62888].
My [npc=38374] soloed the fight.
4. Son of Skum - level 25 beast.
In this fight, I faced Son of Skum, 1 aquatic and 1 flying.
Son of Skum is a 'Boss' (purple) level pet with 50% damage reduction and cannot be dealt more than 35% of it's maximum health in one attack. The other 2 pets are common (white) with no special abilities.
I used the same 3 mechanical pets that I used in the first fight; a [npc=48609], a [npc=55356] and an [npc=77221].
He casts a buff on himself called Stoneskin which reduces his damage by 81 for each attack. So attacks like Turret are blocked. My [npc=48609] got him down to just under 400 health and I finished him off with my [npc=55356]. The [npc=55356] was then able to just kill the other 2 pets, but with the [npc=77221] as a backup, still an easy fight.
5. Phyxia - level 25 beast.
In this fight, I faced Phyxia, 1 beast and 1 flying.
Phyxia is an uncommon (green) level pet with 50% damage reduction. The other 2 pets are common (white) level pets with no special abilities.
Again, I used a [npc=48609], a [npc=55356] and an [npc=77221].
The [npc=48609] soloed the fight.
6. Dreadcoil - level 25 beast.
In this fight, I faced Dreadcoil and 2 other beasts.
Dreadcoil is also an uncommon (green) level pet with 50% damage reduction. The other 2 pets are common (white) level pets with no special abilities.
Again, I used a [npc=48609], a [npc=55356] and an [npc=77221].
The [npc=48609] killed the first 2 pets and I finished the third off with my Tonk.
7. Vilefang - level 25 beast.
In this fight, I faced Vilefang and 2 aquatic.
As with the other 2 snakes, Vilefang is also an uncommon (green) level pet with 50% damage reduction. The other 2 pets are common (white) level pets with no special abilities. Again, I used a [npc=48609], a [npc=55356] and an [npc=77221].
The [npc=48609] only killed [npc=48609], but my [npc=55356] easily killed the last 2 pets.
8. Yet another snake, Hiss - level 25 beast.
In this fight, I faced Hiss and 2 aquatic.
Unlike the last 3 snakes, Hiss is a 'Boss' (purple) level pet with 50% damage reduction and cannot be dealt more than 35% of it's maximum health in one attack. The other 2 pets are common (white) with no special abilities.
Again, I used a [npc=48609], a [npc=55356] and an [npc=77221].
The [npc=48609] nearly killed Hiss, but my [npc=55356] easily finished him off and killed the last 2 pets.
9. First of 2 Growing Ectoplasm - level 25 magic.
In this fight, I faced Growing Ectoplasm, 1 beast and 1 flying.
Growing Ectoplasm is a rare (blue) level pet with 50% damage reduction. The other 2 pets are common (white) level pets with no special abilities.
I used 3 dragonkin pets; [npc=65321], [npc=62201] and [npc=36607]. All 3 used Tail Sweep, Healing Flame and Deep Breath.
The Growing Ectoplasm really hit my [npc=65321] quite hard. It died after only getting the Growing Ectoplasm down to about 30% health. But my [npc=62201] killed it and the second pet before dying and my [npc=36607] finished the fight very easily.
I think the problem with using my [npc=65321] first was that it was an S/S breed and so it went first and made the Tail Sweep less effective.
Put him into the last slot for the second Growing Ectoplasm.
10. On to the second Growing Ectoplasm - level 25 magic.
In this fight, I faced Growing Ectoplasm, 1 aquatic and 1 flying.
The same as the last one, the Growing Ectoplasm is a rare (blue) level pet with 50% damage reduction. The other 2 pets are common (white) level pets with no special abilities.
I used the same 3 dragonkin pets but in a slightly different order; [npc=62201], [npc=36607] and [npc=65321] in the last slot this time. All 3 used Tail Sweep, Healing Flame and Deep Breath.
Much easier fight this time. [npc=62201] almost killed the Growing Ectoplasm leaving it with next to no health. [npc=36607] finished it off and easily killed the other 2 pets.
11. And finally onto the Budding Everliving Spore - level 25 elemental
After reaching the top of the cavern, we confront the Shadowy Figure (lying on some straw near a pile of rocks). There's a little bit of dialogue and then he jumps off a ledge. This now activates the final pet battle, The Budding Everliving Spore.
In this fight, you face The Budding Everliving Spore and 2 beast.
The Budding Everliving Spore is a legendary (orange) level 25 pet with 50% damage reduction and cannot be dealt more than 35% of it's maximum health in
one attack. On top of this, as an elemental, it ignores all negative weather effects. However, your pets will still gain any beneficial weather effects.
The other 2 pets are common (white) with no special abilities.
I used 2 Skimmers/Striders all with Water Jet, Cleansing Rain and Pump.
A surprisingly easy (and disappointing) fight. I put a fast Skimmer/Strider first and used Pump (with one Cleansing Rain after the first turn) and killed The Budding Everliving Spore really easily. A combination of Water Jet, Cleansing Rain and Pump from the other 2 pets finished the fight really easily.
Once this is done, make your way back down to the bottom. Speak with [npc=116781] and select 'I would like to leave the Wailing Caverns'. Ignore the message about your progress being reset (BUT ONLY IF YOU HAVE COMPLETED ALL OF THE PET BATTLES) and you will be ported to the 'other' [npc=116781], outside of the scenario, where you can then hand in your quest.
You will then be offered a 'Pet Battle Challenge' where you have to complete the same pet battles you just did, but without being able to heal ANY of your pets in-between fights.
Good luck all.
