Why the Kraken doesn’t have Legendary Resistance? They are a creature straight out of the myths, but without LRs, they have glaring weaknesses. Their wisdom saving throws and their condition immunities. A caster could dominate monster a Kraken without sweating! Not having Legendary Resistance is definitely a weakness for the kraken. Sometimes we give mighty creatures an Achilles heel.
