You can buy socket scrolls for 50ed by paging a gm or they may be in the moongate- socket display room's ed stones, same price and location for parry augments. Doing the champs in Malas / Ilshenar don't yield power-scrolls or skulls, but they do end up giving 200-500k per champ.
Find a few friends in the NEW guild and hunt those together, 2-3 should be good. The Felucca champs are heavily checked. I look for them every 30min to an hour and still will be late to a champ and end up leaving.
Dante and Domino do champ events daily but usually after 5pm server until late at night. The only way to make real money is to do trade with another player.
Treasure maps very rarely drop a socket scroll (same with MIBs) but even with as little as 1000 luck you should be able to pull up weapon level and magic cloth deeds from level three maps. Those maps should sell for 3-5k each and give me a deed every 3-4 maps. Selling them for a fair price of 70-75k a deed or weapon level gives you approximately 50-60k profit for maybe 7-10 minutes of hunting. Don't bother checking the items inside the chests, they are all trash.
If you have a reagent key, make a steam macro to loot only the regs to add to your key if you want. What I do is use my organizer macro to only pick out the two deed types, runics, and socket scroll (which can be inserted from the socket display room).
I also used to hunt the monster's in the Dread Horn area of the Mushroom Cave, Ilshenar. Cu sidhes drop level five treasure maps often relative to any other monster, and they also drop augments more than any other monster I've found, though it's still verrrry rare. Check that spawn once every 30 minutes or an hour, but do NOT use an area effect weapon. The satyrs there are BRUTAL and must be avoided at all costs. The spiders there also have dropped some 2, rarely 3 skill jewelry and if you get the right stats, with a full suit of fortune armor you have the off chance of getting a very valuable ring or bracelet. I did the cu sidhe spawn for a long time earning gold. Level five maps have stabled in the market at 100k per, and if less, should be bought quickly.
Set up a vendor at Thosar's Mall with Merlina Adams' help and sell your maps there!
There are some people currently getting into making bio pets, so hunting in Ilshenar dungeons for the bio engineers may be a decent way to earn some gold. If you find all the spawns, that should be 1000-1500 organics, which sell for 100g each (100k per 1,000) and they sometimes drop a single dna vial worth 150-175k (the vial sets are almost worthless).
Toxic elementals drop toxic runic hammers, which some players buy at 1-3k per charge. There's a spawn in the big building north of Compassion shrine, Ilshenar and Paraxymous' Palace. Be careful though, they will two shot you. It's best to run in, hit it, run out, wait for swing cool down, run back in, ect. I've made a lot of money and saved money earning valuable items doing the monthly quests.
Your first priority is to find a triple leech double axe with a spell weapon hit on it. Then put a 1h deed on it. Buy a mirror shield. Your armor should be antiquity gloves, tactical mask, and the rest astro demon.
Create a dress agent in UOSteam to switch to your fortune armor set for doing treasure maps. With that gear, you should be fine for about 1-2months while you earn enough gold to put +20 parry in augments and a shield of spikes rune on your mirror shield. From there, try to find people selling Kas armor, as it is the best armor for malee type fighting (mage armor if you're a caster). Keep putting parry augs on your gear and supplement your skill with parry clothing and +15 jewelry. You shouldn't have much trouble getting a +10 or higher parry ring/bracelet from the spiders in Mushroom Cave so you are looking at 140-150 parry right away if you have 120 parry from a scroll. That's plenty to solo champ spawns.
It's not much but it's what I did for months to get my character built. Like others have said, this isn't a sprint race, it's a marathon. If you want to complete the game fast, donate. I have only donated $10 and have earned my 36x36 house, 217 parry suit, perfect double axe, and sin shield. It's taken about 1600 hours of game play, but it's definitely doable.
Thank you very much for the detailed post!
