Legends and Lore
With an Arcana or Religion check, characters can learn the following:
DC 10 Krakens are gigantic leviathans whose power rivals that of the gods.
DC 15 Like the squids they resemble, krakens release clouds of ink when threatened. Their tentacles can rip a ship in half.
DC 20 Krakens can summon storms and call down lightning from the heavens.
Some sailors have encountered krakens and lived to tell about it, but even old salts speak in hushed voices of the leviathan they call the Kraken. It’s said to be the first of its kind, created by doomed titans to be a spear thrust into the heart of the victorious gods. It is possibly the parent of all other krakens.
When a kraken awakens from slumber, it rampages along the coast, summoning storms and leaving death in its wake. It is a force of pure destruction. It takes no treasure or prisoners.
