Hestia overall felt like one of the weaker gods (prior to the 6/26 patch), but she is unquestionably powerful here for one simple, and extremely cheesy reason.
I like watching people who are better than me at this game because They go through the game quicker and kinda unlock less stuff meanwhile I have a ton of unlocks yet struggle to beat polyphemus and the mourning fields. Also hey you kinda out trolled the troll with the Hestia boon right there
Honestly, I'm still having trouble with Polyphemus and Cerberus too! I love these games because even when I lose, I still feel like I'm making progress or seeing new dialogue. I prefer the more casual progression they permit, but can also switch into a more gameplay focused playstyle on a whim.
