Only looks like that. I has a trick to it, if you try to regenfight the Avatar, you'd probably get trapped, so winning parched won't be that easy.
If you're unfamiliar with EM Gorgons, try it somewhere easier. You'll see some early stacks of Vineform and Greenblood helps greatly, even on Vicious dungeons, and once your poison becomes stronger it will be a cakewalk. EM is a great piety farm, so she will be really useful when converting into another religion. If you know you're not gonna stay with EM you can take some Clearences mid run as well, bumping the cost of that boon is not a worry if you won't use that for the bossfight.
