I've started probably 4 different games, and the one I completed I played as Oracle Ceresa. The one I completed was thoroughly enjoyable, although I relied heavily on the mass poison spell (can't remember the name) to wipe out armies much more powerful than me.
I haven't found another faction with as much power as an underdog. Not only the mass poison spell but the numerous elementals created from the various shard sites, made it uniquely powerful.
Karavox seems ok, but with diplomacy being unpolished i'm not sure if I can overcome all of the other factions who hate me now.
The Tarth are interesting in that they can avoid monster combat, but I was unable to overcome the other factions.
Has anyone else won a non conquest victory, or is that just the easiest path to win at this stage of the game development?
