I killed an ostard the other day... it didnt drop any gold. One day I'll get lucky and find one with awesome loot! In reality I could make 300k-400k per-day if time allowed and I made it a priority. Its honestly been a long while since I focused on income.
Currently just building up characters and enjoying being back in a UO shard that feels as close to the ole days as you can get. I am mainly escorting up my gold at this point, when few others are running escorts I can bring in 25-30k+ an hour casually with basically no risk. If it's busy I can average 15-20k. This keeps me in all the training materials and regs I need and buys my starter houses. Once I get some characters like I want them I will explore the world here and find the spots I like for farming type gains.. but I don't need much gold to be happy. My funnest characters I play get excited about bank scavenging for beer money. I am thinking about starting a character who has no fighting or crafting skills and scavenge his/her way to a small house. That is my kind of UO.
