Didn't seem to get any levelling but worked great.

XP with Sign of the Critter, Hat and WQ up: My leveling pet got 2268XP
- Repeating the fight after the WQ was already complete a level 1 pet got 1827 XP (8 Levels) (edited)

I have some changes to this fight that worked well for me just because of the RNG he has to deal with. Is is Just my personal thoughts and observations.
First, just a correction.
Blistering cold has a 2 round cooldown, so the Turns are not really accurate under strategy. It should be Blistering Cold followed by 2 rounds of Chop. Repeat.
Bonestorm! does such a small amoung of damage (sorry didn't write it down; like 50 points more than Chop?) that it does not seem worth it to lose that much health for one small attack. His RNG makes him miss so often I think it is better to conserve health with the hope of inflicting additional Blistering colds. My Bonestorm had 15 health for 3 rounds before an attack finally landed to kill him. But that allowed him to add one more Blistering Cold.
Also, when I died the first time and knew Blistering Cold was on its 2 round cool down, with only the one round left, I'd rather use the higher damage move with the high chance of missing. It's my last move anyway. Freaked me out when it actually landed.
I did not use a small level pet. Doesn't one training stone add 2000 XP? I use fights like this when I have a pet partially into a level, particularly level 24. I hate wasting a stone on a pet that needs less than that 2000 XP to level up. I am certainly glad I did, He killed my Ikky and gained some health. Gratefully, it was nothing my level 24 Beetle couldn't handle and won the fight for the XP.
Especially when the fight is for battle stones, I'd just as soon get done and move on the the next World Quest.

I've modified and works each time:
Turn 1 - Chop
Turn 2 - Blistering Cold
Turn 3 - switch to Ikky
Turn 4 - Black Claw
Turn 5 - Flock, and you're now done

I had a BB Boneshard and he lived WAAAY longer than the script

Awesome strat! Got this down to a nine turn maximum with the below script. It's not much but just wanted to optimize a little when rotating through multiple characters for token rewards.

On average this finished on turn seven and as early as turn six roughly 6% of the time.

Hell yes! I've been looking and waiting for a leveling fight team. Thank you. Worked flawlessly. I agree with what others have said. Removing the Thanks line or it errors every time.

Please remove the "Thanks" from the script, it will interfere when copy/pasting it to the addon.

Script if you'd like one:

change(#2) [self(#3).active]
use(Blistering Cold:786)
use(Chop:943) [!enemy.aura(Bleeding:491).exists]
use(BONESTORM!!:1762)
use(Chop:943)
use(Black Claw:919) [!enemy.aura(Black Claw:918).exists]
use(Flock:581)
standby
change(#3)
