IIRC, only Besaid and Macalania are blocked by Dark Aeons. You can get to the other Trials without fighting any Dark Aeons. If you need to get into those two Trials, I'd say you'd need to work on the Monster Arena sidequest: by capturing enough monsters of a type, you unlock a boss which can be killed for Strength, Magic, etc. spheres, which you then use to improve your characters. I'd say the most important ones are Strength (horned monsters), Accuracy (insects?) and Agility (wolves). Against many of these unlocked monsters, a Hasted, Protected/Shelled Aeon with Lancet will kill them easily, if slowly. |
