Oceans: Legends of the Deep expansion Overview

About Oceans: Legends of the Deep, from BoardGameGeek:

Legends of the Deep brings cultural legends, high fantasy, and mythologies from around the globe into the Oceans ecosystem. Oceans is a journey from the known world into the unknown, where you discover powerful traits that hardly seem possible in the realm of biology. With Legends of the Deep, you will discover things beyond the world of science! At the beginning of the game, deal four Legend cards to each player. Choose one of them, and pass the rest to the player on your left. Continue drafting until everyone has four Legend cards. During your Play Cards phase, you may play one Legend card in addition to your normal card play. Legend cards have game-changing abilities with global effects. To replace an Legend card with a new one, subtract the cost of the old Legend card from the cost of the a new Legend card. -description from publisher
