In that mode time is of no cncern, so you can afford to take the stables to the Erthia and the Forest. In both places you can visit the altar and get stat boost and pick up horseshoes for skill points.

Erthia has a Day Of The Gods pedestal that will allow you to win at the brazier out in the hills for more skill points.

Visit the fountains for additional perm and temp boost. Get bow skills, if you did not have them and try to get bows. One way is to sneak out to the mad forest in Tularean Forest, but be careful the trees can kill low levle parties.

Just take down weak monsters as you can and visit all buildings. You can get some quest that you may be able to handle.

Concentrate skill points to get to expert levels in key skills. Namely magic for spell casters. Have one member learn merchant, one learn disarm, if you have anyone that can.

Note NPC's and hire one if it can be usefull. Gate Keepers are great, but will take lots of your income. This is not a problem for experiencd players, but others may find it hard to get by.

Harmdale has some weaker monsters, as long as you stay away from large groups. Search the areas for chest and stuff on the ground. The Cliffs can be tackled, but if you do not have a wand you will need to avoid the oozes as only magic works on them.
