makes me wonder ..how do we know when we're out of Vigor? 

I'll cost 10 silver coins to change factions. Might be a little bit expensive when you're still doing Act 1 quests but once you get to Act 2 and you join those crafting guilds, you can start earning a few silver coins a day from crafted items.

Later in Act 3, you'll start getting 2-3 silver coins for each of the quest rewards.

Unnecessary blue (rare) accessories or purple (hero) weapons from loots can be sold to players in the Auction House for silver or gold coins.
Indeed, like what ChocChristy said, the bots are farming for the following costume:



Kill a few of the Bamboo Village there and Dao Tianfeng will show up to attack you. Defeat him and you'll get a special token which you can collect until you get 40 pieces to be exchanged for the costume.

hi gys.. can anyone tell me what is this thing? wat does it do?

less thn 1 hour :3

just wait till the boss appear and just hit him few times.. run away and let the ally npcs kill em.. 

Yeap. Let all the bots do the work for you - that's what bopiang taught me.

You only need to wait for Dao Tianfeng to show up and land a few hits on him. Then you stand back and wait for the bots to defeat him before you go collect your loot.

Won't take long at all if there are bots there. If you don't see them, try changing channels as I usually see them on Channel 4.
