I did the quest today, and i survived, for the simple reason that i didnt do a thing :p
The easiest to get godess if you are not that high level (im lvl 57 xD) is just defend, and sit the battle out.
That way, you dont risk getting spawned and such.
Getting high lvls in your party helps too :p
Anyhow,its possible to do the quest without terra,earth wall and such.
