Hello all!
I made a more simplified TdScript for Crysa. Please do let me know if you have issues and I'll work on fixing it! =)

Pet Order
Slot 1: Nexus Whelpling (P/P - 1/2/2)
Slot 2: Leveling Pet
Slot 3: Stormborne Whelpling (P/S - 1/2/2)

TDScript
change(#3) [self(#2).active & self(#2).played]

change(#2) [enemy(Buzz:1982).hp<=750 & self(#1).active & !self(#1).dead & !self(#2).played]

change(#2) [self(#1).active & self(#1).dead & !self(#2).played]

use(Arcane Storm:589)

Happy hunting & Light be with you!

So, just did this today and came across a slight bump in the road. My first nexus whelpling, which is a P/P breed, just solo'd the whole fight, never swapping to the level pet thus it did not receive the XP. Any way to fix this in the script with a condition? This is probably a 1 in X chance of this happening or maybe need to use my P/B breed nexus instead in the future.

These scripts stops the first Nexus Whelpling from defeating Crysa before the levelling pet has been active. It will also make smarter decisions on what moves to use.

This is the script for two P/P Nexus Whelplings:

quit [self(#2).dead]
change(#2) [self(#1).dead & !self(#2).played]
change(#1) [self(#2).played & !self(#1).dead]
change(#3) [self(#2).played & self(#1).dead]
change(#2) [!enemy.ability(Reckless Strike:186).usable & !enemy.ability(Preen:1545).usable & enemy.ability(Lift-Off:170).usable & !self(#2).played]
standby [!enemy.ability(Reckless Strike:186).usable & !enemy.ability(Preen:1545).usable & enemy.ability(Lift-Off:170).usable]
use(Arcane Storm:589) [round=1]
use(Mana Surge:489) [round=2]
if [enemy(#2).active]
use(Tail Sweep:122) [self(#1).active & !self.aura(Dragonkin:245).exists & enemy(#2).hp>451]
use(Arcane Storm:589) [self.aura(Dragonkin:245).exists & enemy(#2).hp<=548]
use(Arcane Storm:589) [enemy(#2).hp<=365]
use(Tail Sweep:122) [self.aura(Dragonkin:245).exists & enemy(#2).hp<=676]
use(Tail Sweep:122) [enemy(#2).hp<=451]
endif
if [enemy(#3).active & !self(#2).played]
use(Arcane Storm:589) [!self.aura(Dragonkin:245).exists & enemy(#3).hp>1370]
use(Arcane Storm:589) [enemy.aura(Flying:341).exists & enemy(#3).hp>1096]
use(Tail Sweep:122) [enemy(#3).hp>1269]
use(Tail Sweep:122) [!enemy.ability(Reckless Strike:186).usable & enemy.ability(Preen:1545).usable & enemy(#3).hp>969]
use(Tail Sweep:122) [!self.aura(Dragonkin:245).exists & enemy(#3).hp>846]
use(Tail Sweep:122) [enemy.aura(Flying:341).exists & enemy(#3).hp>677]
use(Tail Sweep:122) [!self.aura(Dragonkin:245).exists & !enemy.ability(Reckless Strike:186).usable & enemy.ability(Preen:1545).usable & enemy(#3).hp>546]
change(#2) [!enemy.ability(Reckless Strike:186).usable & !enemy.aura(Flying:341).exists]
standby
endif
use(Mana Surge:489) [self(#2).played]
use(Arcane Storm:589)
use(Tail Sweep:122)

And this script is for a P/P Nexus Whelpling in slot #1, and a P/S or P/B Nexus Whelping or a Stormborne Whelping in slot #3:

quit [self(#2).dead]
change(#2) [self(#1).dead & !self(#2).played]
change(#1) [self(#2).played & !self(#1).dead]
change(#3) [self(#2).played & self(#1).dead]
change(#2) [!enemy.ability(Reckless Strike:186).usable & !enemy.ability(Preen:1545).usable & enemy.ability(Lift-Off:170).usable & !self(#2).played]
standby [!enemy.ability(Reckless Strike:186).usable & !enemy.ability(Preen:1545).usable & enemy.ability(Lift-Off:170).usable]
use(Arcane Storm:589) [round=1]
use(Mana Surge:489) [round=2]
if [enemy(#2).active & self(#1).active]
use(Tail Sweep:122) [!self.aura(Dragonkin:245).exists & enemy(#2).hp>451]
use(Arcane Storm:589) [self.aura(Dragonkin:245).exists & enemy(#2).hp<=548]
use(Arcane Storm:589) [enemy(#2).hp<=365]
use(Tail Sweep:122) [self.aura(Dragonkin:245).exists & enemy(#2).hp<=676]
use(Tail Sweep:122) [enemy(#2).hp<=451]
endif
if [enemy(#2).active & self(#3).active]
use(Arcane Storm:589) [self.aura(Dragonkin:245).exists & enemy(#2).hp<=493]

use(Tail Sweep:122) [self.aura(Dragonkin:245).exists & enemy(#2).hp<=609]
use(Tail Sweep:122) [enemy(#2).hp<=406]
endif
if [enemy(#3).active & !self(#2).played]
use(Arcane Storm:589) [!self.aura(Dragonkin:245).exists & enemy(#3).hp>1370]
use(Arcane Storm:589) [enemy.aura(Flying:341).exists & enemy(#3).hp>1096]
use(Tail Sweep:122) [enemy(#3).hp>1269]

standby
endif
use(Mana Surge:489) [self(#2).played]
use(Arcane Storm:589)

Oh, these scripts assume that the third enemy pet Buzz's Preen ability will heal for at least 300hp if it's used. The lowest I've seen it heal for is 306hp, but if it can heal for under 300hp, then there's an extremely small chance that the first Nexus Whelpling can win the battle before the levelling pet has been active. :p (edited)

are you sure you couldn't make the scripts any longer?

You don't have to type the scripts by hand into the game, your computer does have a copy and paste functionality.

There is no need to make the scripts shorter, every line is in there for a reason. (edited)

Nether Faerie Dragon 2,2,1 and Void Jelly 2,2,2 allows for a level 1 pet to be brought in. Start with Faeire using Moonfire and nuke until it dies(do not use Life Exchange). 2nd pet comes in you cast Life Exchange. You need to adapt to the fight now because of rng. Basically bring out the jelly when 2nd pet uses the group whirlwind and purge it. Nuke the bird down. When last pet enters cast Barrier and bring in leveling pet. Bring in Faerie and Life Exchange as enemy pet beats down barrier. -- There can be some wonky RNG but it's somewhat rare. It's the only strat that allowed for a level 1 pet that worked somewhat reliably for me.

I used a lvl 5 beast (373 HP) and it was dead well before the last bird was dead.

BTW, is this once per account per day? I went there on another character for the 1st time and no quest.

Crysa is not offering me daily Q from patch 8.1 - is it bug or it was removed?

Same for me :( I'm at 41 tries too.

seems they patched it after all our bug reports.. just did it on my 60 ish toon

Nexus Whelpling 1/2/2 + Mechanical Pandaren Dragonling 1/2/1 + Any Level 5+ Pet

Arcane Storm-> Tail Sweep-> Mana Surge (2 enemy pets should be dead now)

Mechanical Pandaren Dragonling

Thunderbolt/Breath until:

1) enemy pet is in Explode Range (560 HP or Less)
2) enemy pet used his Lift-Off (Lasts 2 rounds)

After Lift-Off hits you-> Explode

I've been using the #1 Strat since I started doing this fight and today decided to try this one--like this one a lot better, is faster and gets the job done just as good!

TD Script

Thanks for the script, works great, gotta love tdPetBattleScript :)

Changed the script, as my leveling pet started attacking, it was a Court Scribe, it had the abilities so it started using them haha

quit [self(#2).dead]
change(#2) [!self(#2).played]
change(#3)
ability(Arcane Storm:589)
ability(Mana Surge:489)
standby

edit: haha just realized i was the previous reply

Apologies, forgot to account for the first pet being dead, just did the fight again today with the above script and it switched to pet 2, then 3, and failed when pet 3 died, problem was I was already on the second pet yesterday when I changed the script to the above, this one works :) Added tail sweep, though it wont usually get to it.

quit [self(#2).dead]
change(#2) [self(#1).dead & !self(#2).played]
change(#3) [self(#1).dead]
ability(Arcane Storm:589)
ability(Mana Surge:489)
ability(Tail Sweep)
standby

tdScript if anyone is interested:

if [enemy(#1).active]
ability(Arcane Storm) [!weather(Arcane Winds)]
ability(Mana Surge)
ability(Tail Sweep)
endif
if [enemy(#2).active]
ability(Arcane Storm) [!weather(Arcane Winds)]
ability(Mana Surge)
ability(Tail Sweep)
endif
change(#2) [self(#1).dead & !self(#3).played]
change(#3) [self(#2).played]
if [enemy(#3).active]
ability(Arcane Storm) [!weather(Arcane Winds)]
ability(Mana Surge)
ability(Tail Sweep)
endif

Great strat and thanks for the tdScript.

For a certain time, instead of the second Nexus Whelpling, I use an Arcane Eye (2/1/2). I find it a bit smoother, but don't treat is as an edict. :)

I use a mechanical dragon on the last bird and explode around 520 health. Your level pet get the exp.

Worked great , thanks !

Works also with level 1 pets, at least all the times i'v checked.

Swoop can throw out a Cyclone that might take out a level 1.
