<p>I have killed 13 Ocyakaos so far and looted eye of the storm in my 7th.<br>However, based on my own observations (since the implementation of Ocykao Ocyakao to the game in 2013) including:</p><ul><li>how often is Ocyakao killed</li><li>how often is eye of the storm being sold on in-game market markets of various servers and trade boards of tibia.com</li><li>how often does it appear on screenshots sent to Tibiabosses.com</li></ul><p>I estimate the drop chance to <strong>1%</strong> so 1 eye per 100 bosses killed.<br>Please note that this is an estimate, currently there are no available databases with significant kills/loot stats of this boss.<br><br><img alt="" src="https://i.imgur.com/GqxFeXB.png" style="height:732px; width:1365px"></p>
