My original plan, starting out in A4, was to make a duo. An Elite Warrior/Fast on Feet melee/archer kitty and a divinely touched/natural mage mage/priest.
But, smart like I am, I completely neglected tool use, AND my doods didn't have the strength to carry all the loot I wanted.
When I got tired of not being able to open locked doors and getting killed by traps, I upped the party to 3. The third, completely useless guy, is a mule, and a walking lockpick. (16 tool use and a couple points of arcane/nature lore ) His weight is something like 230/90, which is okay because he can't do anything useful in combat anyway.
So far I have had a lovely time killing things (my warrior used a Stick right up until my first Blessed Shortsword, and even then I couldn't tell much difference >> they're actually quite nice) and hitting space every once in a while to skip Juan Valdez's 2-AP turn. (if I strip off his armor and give him a girdle of strength, he gets 3AP -- enough to use a scroll or wand! Yahoo!)
