There's a Youtube tutorial here on this specific mission and the ingredient locations (if you want to watch through the entire video).

The percentage increase from Crackerjack is 10% and Crackerjack II is 20%

Here is what I have observed. A Normal pack in the Winter Isles -

• JabberGuppy
• Lotus Bubbud
• Sasquash

gives 243xp without any bonuses.

With Crackerjack we get 266xp. With Crackerjack II we get 291xp.

So lets compare with creature compendium -

• JabberGuppy - 75xp
• Lotus Bubbud - 81xp
• Sasquash - 87xp

Total XP = 75 + 81 +87 = 243xp.

Now with Crackerjack it should be 243 + 10% = 243 + 24.3 = 267.3 which should be 267. But it is not because the bonus is calculated per creature!

so it would be -

• JabberGuppy - 75xp + 10% = 75+7.5 = 82.5 = 82xp
• Lotus Bubbud - 81xp + 10% = 81+8.1 = 89.1 = 89xp
• Sasquash - 87xp + 10% = 87+8.7 = 95.7 = 95xp

All fractions are rounded down.So now we get total to be

Total XP = 82 + 89 + 95 = 266xp!! (Which is what the game gives us)

Similarly with Crackerjack II -

• JabberGuppy - 75xp + 20% = 75+15 = 90xp
• Lotus Bubbud - 81xp + 20% = 81+16.2 = 97.2 = 97xp
• Sasquash - 87xp + 20% = 87+17.4 = 104.4 = 104xp

Total XP = 90 + 97 + 104 = 291xp

In summary -

Crackerjack - 10% xp bonus monster xp
Crackerjack II - 20% xp bonus monster xp
