I've just recently purchased Well of Darkness and Altar of Despair (leaving Road to Legend as the only part I don't yet have). With treachery points at such a premium in quests, it's tough to decide on how to spend them, now that I've got so many options.
I'm hoping some people can provide some insight on specific quests where, for example, a rolling boulder trap was especially useful / not useful, as well as when they decided to use Dark Glyphs, Dark Relics, etc. Thanks!
