You want advice on how to easily get uniques? Here are some:
-Look for contracts that involve killing Hedge Knights, they usually have unique weapons to drop.
-Take time to go into the wild, look mostly for crypts, fortresses and graves, I got many uniques from there.
-When you have like 20000-40000 gold, search in all the towns for uniques. Try to not waste money on useless things like having 20 men, 8 men get paid like 200-300 gold per day, I always have a 12 man roster to not waste much money.
