Scyl of the Drakes is a Magic affinity legendary from the Barbarian faction. She is a login reward on day 180 of playing and probably the best login reward in the game! Absolutely fantastic she can slot straight into multiple teams with utility such as AOE stuns, passive heals, decrease enemy speed and 1 man revives.
Scyl is strongest in dungeons and Faction Wars but really can play anywhere and for most players will be a huge step up for their account. I personally really like Scyl in Relentless gear to enable you to cycle back through her abilities as fast as possible. You do need to ensure Scyl has enough accuracy (take the dungeon level you are on then multiply that by 10 as a good indicator) and a strong amount of speed and defence to really shine!
Overall a fantastic legendary and well worth taking to 6 stars.
