Crimson Sea Anaconda

The Crimson Sea Anaconda is an epic jungle snake, categorized as a "fish" and only obtained by Fishing.

The Anaconda is not food nor quest-related, but it can be "looted" for 50% chance of getting either of the following items:
 * Plunderer's Beacon


 * Chestguard of the Sunken Hero

How to obtain
It can be caught anytime with any lure within the Jungle Island. Due to its rarity, a high fishing stat and a Gambler's Lure is recommended to catch this snake.

Trivia

 * Anacondas are known to squeeze the air out of big preys, like a pig (or in this case, humans). The Chestguard of the Sunken Hero is likely the remnant of some sort of historical hero that was eaten by the Crimson Sea Anaconda.
