vs Whispertail
- Crush until your Anubisath Idol dies
- Switch to Carry pet > switch to Emerald Proto-Whelp

A level 25 Emerald Whelpling or Emerald Proto-Whelp with Emerald Presence selected as the middle skill destroys this trainer. A green whelp is able to solo all 3 of this trainer's pets without any help from your other pets. Just keep up Emerald Presence (refresh at 1 round remaining), heal as needed, and attack otherwise.

Each of the enemy pets uses only flying attacks that hit multiple times for low damage. With the green whelp's dragonkin-family damage reduction, any damage not prevented by Emerald Presence is easily healed with either Tranquility or Emerald Dream.

On the pandaren air elemental, you will need to skip healing yourself in order to out-damage its healing, but you will still be full health after defeating the other 2 pets. If you heal to full, then refresh Emerald Presence, you should be able to finish the elemental before your whelp dies by just spamming your damaging attack.

hi wowhead users,
simply yet effective guide on farming all legendary spirits with only 2 pets!
as a result you can level a 3rd pet on any trainer which gives insane amounts of XP

you will kill any legedary trainer first try unless you have an insane amount of back luck!

AIR: (hardcounter vs all 3: dragons)
any dragon with tail sweep will do, healing flame is nice aswell, use 2 of them (e.g. [npc=36607])
if you don't have a second dragon pet, don't worry, your dragon will almost kill 3 guys solo; any 2nd pet will do that is not aquatic
chose your 3rd pet as desired (leveling pet or w/e)

WATER: (hardcounter vs all 3: magic)
i strongly suggest the [npc=15429] since he can solo all 3 pets without dying using absorb/acidic goo/corrosion
if you want backup, chose another magic pet or any decent flying pet such as [npc=65124]
chose your 3rd pet as desired (leveling pet or w/e)

EARTH: (the is no real hardcounter sadly, but a fast critter will work wonders)
get a critter that is faster than the earth spirit such as a [npc=62178] that can make use of strong defensiv cooldowns like dodge and burrow
the second pet is more tricky, since you need to kill 2 guys fast. i've done a lot of testing - long story short - [npc=68838] is the way to go
chose your 3rd pet as desired (leveling pet or w/e)

FIRE: (again no real hardcounter ;( )
depends on that the NPC starts with (you might restart the fight if its the wrong pet) use your fast critter pet such as a [npc=62178] to kill the fire spirit and dps down the dragon as far as you can
then go on with a dragon pet yourself like [npc=36607] once you have killed it, the flying pet is no match.
