the kraken can be easily killed WITHOUT any losses
use archmage/beholders/inqisitours/shamans/(insert ANY RANGED unit here)
first turn bring your shaman close to one of the tentacles
cast
phantom on it and use the mage shield on it
and maybe magic SPRING if u are a mage(dual cast)
and keep placing totems around your army
and every turn keep casting phantom
and surround your army with those totetms
untill no spots are left
and the kraken get's bugged(it never spawns anymore deviilfishesn nor does it do any damage
and if it does the shaman will soak it up
(oh and keep all TENTACLES at LOW HP like 100 health left or something so u don't have anymore devilfishes left to place on
then go kill all tentacles at once
and gg kraken
