Grand Master Aki

Aki the Chosen is the final Grand Master Pet Tamer you need to defeat for Taming Pandaria. You must have already completed Battle Pet Tamers: Pandaria / Battle Pet Tamers: Pandaria.

Her pets are:

• 
  
• Chirrup - a level 25 [npc=63370] (1600 Health / 300 Power / 375 Speed), with the abilities [petability=298], [petability=573], and [petability=706]
• 
  
• Stormlash - a level 25 [npc=65321] (1769 Health / 334 Power / 300 Speed), with the abilities [petability=204], [petability=347], and [petability=122]
• 
  
• Whiskers - a level 25 [npc=63841] (1600 Health / 334 Power / 334 Speed), with the abilities [petability=564], [petability=509], and [petability=283]
• 
  

Counter her Critter / Dragonkin / Aquatic team with Beast / Humanoid / Flying pets and abilities respectively.

Defeating Aki will also unlock the Panderia Pet Battle Daily Quests.

OP & easy-to-get pet for this battle: [npc=68659]. Allows you to kill all 3 enemy's pets solo with 3 abilities: 1, 2, 3).
(upd. after mininerf Idol can unluckly die on 3rd pet, it's okay, just keep ready some high-lvl moth (f.e. [npc=21010]))

As well (thanks for [petability=453]) when u're fighting with Chirrup u're taking 0 (zero) damage, that means u can activate (even) 1lvl pet, hit 1 time and switch them back.
1lvl Battle pet gets 3625хр and becomes 10lvl (+71% more) (without magic hat or food)

p.s. read up enemy's abilities in a ^ comment. I always deflect only Dive (it's 2 round ablilty, press deflect when enemy is already under the ground), but mb you want to also deflect [petability=204] or avoid dmg from passive dragon buff
p.p.s. screenshot
p.p.p.s. sadly we can't abandon Grand Master Aki, but it's still great for lvling pets.

As a curious thing, when you challenge her the first time, she says you'll receive as reward a "Heavy Sack of Gold". After defeating her, she gives you only 9 gold and 80 silver coins... until you check your mail, where you'll get a 3000g from her and a letter which starts with "I thought there was no way you could beat me..." ;)

A word of advice, every body always says "you can counter this pet type with this one", but the truth is use those you trained and you know well. Every time I listened other people's advice about what type is stronger against any other, I lose. Whenever I used the ones I trained and I knew what they were capable of, I won.

I defeated Aki with a team of my own, completely different from the recommended one at first try with no problem at all.
