Though most Warriors of Light are familiar with the idea of FATEs inFinal Fantasy 14, rare boss FATEs are a little more elusive and yield particularly coveted rewards. Dawntrail introduced a couple of new rare boss FATEs, including ‘The Serpentlord Seethes’, which rewards players with Ttokrrone Scales.

You’ll want these scales if you want to get your hands on the Mehwapyarra Whistle that gives you the adorable capybara mount. Here’s everything you need to know about this FATE, including where it takes place, the pre-requisite FATEs, and how often it spawns.

The Serpentlord Suffers

Once you successfully complete a FATE,the next should spawn within a few minutes, with the fourth appearing instantly in the same location after completing the third. If the window is open for this particular FATE, ‘The Serpentlord Seethes’ will spawn within a few minutes of completing ‘The Serpentlord Suffers’.

The window for this FATE is up to 72 hours after it’s last known spawn, which meanscompleting ‘The Serpentlord Suffers’ does not guarantee the boss FATE will spawn next.

Once ‘The Serpentlord Seethes’ FATE has spawned,it will not spawn again for at least 24 hoursand will be in “cooldown” during this time.
