I've just started playing DBII and am enjoying it during my NYC
commutes.

Quick question before I get to deep into the game and find I've made a
mistake.

My party consists of Knight, Archer, Thief, Wizard and Necromancer.
All 6th level except the thief (3rd level) (as I went through 5 levels
with the Troglodyte before I changed). Is this an OK party to continue
with? Should I change something? I've only been in the wilderness and
am ready for the Sewer now?

I don't want to have 50 hours invested and find out I can't defeat
something because I built up the wrong characters.

Thanx,
Chris
