Farming

The Hall of Monuments stuff is much easier to get if you can just buy it. But getting that kind of gold is hard.  Many people resort to a mind numbing but profit rich technique called farming.  Farming will get you lots of gold in a timely fashion.

Feather Farm: Any Factions char can feather farm. Just go to to Seitung Harbor with a character that can kill the Sensali bird people in Jaya Bluffs as quickly as possible. Spirit Spammers are very fast at this. All you do is pick up all the feathers and feathered crests and sell them for 8-10k per stack of 250 feathers. You do the match at a stack every 30 minute run.

Vaettir Farming: Certain monk and assassin builds farm the Vaettirs in Jaga Moraine very quickly for gold drops and glacial stones. Glacial stones can be sold for ~8k per 100 stones. Golds can either be sold in sets of 7 for ~5k unidentified, or you can ID them and salvage any perfect mods and sell those. Selling sets unidentified is really the fastest and most worthwhile way to go. This run is fast and fun in my opinion. You come back to town after ~30 min farming with about 20k worth of golds. The hard part is finding a buyer. You may have to sell at 4.5k per set of 7. That's ok though because it saves you lots of time that can be spent farming more golds. I make it a point to ask the buyer if they want me to add them on my friends list so i can notify them when i have more golds. If they say yes, never change the price unless they want to lower it from 5 to 4.5k. Anything less than 4k isn't worth your time. Having a buyer will greatly increase your time available to farm.

Consets: This farm is fairly difficult as it isn't a single area. You must farm the materials needed to make specific consumables for players that do dungeon runs. Here is a link to the wiki info: WIKI. Sell a set of 1 of each for 8k. This price is pretty much standard so i wouldn't negotiate unless they offer higher. Again ask if they buy consets regularly and if you can add them to your friends list.
