Newbie Guide
Companions - get them fast: Cassandra from the church, Marta is up North in the Deep Wood, Dimanda from the Adventurers Guild, Parsifal from the island in the Deep Wood and Ketola from St. Ristos far South from Profound City. There are others too, like Roki will join you if you've been in the Keen Keep. Loretta can join you too later on.
Experience - get it: probably the best place to visit first is the Profound City sewers, or if you have few companions go the Deep Wood.
Equipment - equipt it: otherwise it's no use. Remember that not everyone can use everything.
Good luck!
