Smite has officially unveiled Isis with her own custom spotlight video after unveiling her on the official stream earlier this week. In a change, it seems that Hi-Rez is no longer putting the lore at the beginning of reveal videos.
In the game, they're referring to her as the goddess of magic, and that's not too far off given her magical abilities and winged design. Isis has a unique basic attack which has three parts to it, all dealing magical damage. The third time she attacks that hit will carry a slight damage bonus, and also land in a small AOE. Isis is a Mage in Smite, and while she has damage, she can also support. Enough stacks of Funeral Rites, and you buff your allies well. Her ultimate is going to be great for team fights because you will AOE heal as well as damage your enemies.
