Question: Defeat Kraken in any battle (except training)

Hiya folks, apologies if this is an obvious question, but my current campaign says;

“Defeat Kraken in any battle (except training)”

I let it take me to where it said I needed to go (Divinion Fields), but there’s no mention of Kraken there. Just wondered how I can complete this campaign please?


Kraken only appears on Blackhawk explore (Mini-Boss - 33% chance to get him, since the kingdom has 3 legendaries).
Your other option is finding the troop on pvp.
My defense, for instance, has 2 Krakens (last week’s troop) and 2 Stronghorns (this week’s troop) to help.

Very much appreciated, thank you (still new to the game myself lol)
