Usually I do the Monestary, Arnika and Mine Tunnels thoroughly but avoid as much as possible on the roads and outside in Trynton and on the Bluff (while doing what is necessary on the Bluff to get to the teleporters. Gigus and start Umpani Quests, teleport (mostly) to Arnika, pay off He'Li double agent blackmail, monestary, arnika, trynton and/or graveyard and graveyard dungeon, arnika back to bluff and surrounding areas and quests, finish swamp, etc. To answer, sometimes I mix it up, but I guess my favorite sequence is Arnika, Trynton up to the 2 fountains and Fuzzfas, Swamp to Crock, Mine tunnels, Bluff and start Bug quests, teleport (mostly) to Arnika, Then go to Mt.
