I used this script during the beginning of nq2...but it wouldn't attack with velm so i had to play manually after the lost desert. (you need to set velm up with the group healing skill.) and it just battles and moves for you till u reach ur destination. It doesn't automatically train skills, sell items, equip items, or finish the game without manual aid.

I haven't tried this but it seems safe.
