I never minted a single coin and still got a Tax Collector in about my 5th year - perhaps the trigger is wealth created or exported? --GameHat

Moved that from the article, Mr Hat. Anyway, I agree. I never minted a coin, and still got the Tax Collector. Runspotrun 23:34, 18 November 2007 (EST)

My Tax Collector has a [happy] thought "Was happy to have pleased a noble". The Count has a [happy] thought "Was pleased that the tax collection went smoothly". --Another 13:01, 25 November 2007 (EST)

Captain Mayday on the official forums got a tax collector during his Nist Akath story, as far as i know he doesn't have metal for minting coins his created wealth etc was this:

Imported Wealth: 330339
Exported Wealth: 42119
Actual fortress wealth is at 859403

hope this helps in some way --Bullion

I had a tax collector arrive together with the baron, baroness and hammerer, population of 13 due to bronze colossus encounter. Fortress type is city (it doesn't decrease with population loss) Coelocanth 22:38, 2 December 2007 (EST)

I recently got a fort far enough along to get this noble. I certainly had not minted any coins. What seemed to do it was my population passing 100. He arrived, along with the Baron, Consort and Hammerer in a wave that brought my population from the low 90s up to 115.

I think wealth is also required, passing 100 population brought me only the philosopher in said fort. Has anyone got the tax collector without a baron or vice versa? Coelocanth 17:57, 5 December 2007 (EST)

I just got my baron, collector, consort and hammerer. The year is 1064, my population is 100 on the dot (at the note of the arival of the nobles)

I have:

388732 imported wealth
67325 exported wealth
506478 created wealth
4336 weapons
45840 armor and garb
65710 furniture
227955 other objects
74200 architecture
37877 Displayed
50560 held/worn.

-ellipsis (not sure how to fancy up a signature in here)

It seems that having 100 population is a major factor in getting the economy.

I just got the tax collector with a couple of other nobles, its 1054 Mid-Spring. My pop is 99 now.

Created wealth: 763,020
Imported Wealth: 221,438
Exported Wealth:  21,747

I just got a tax collector, hammerer, count (and consort), and philosopher. It is Mid-Spring of 1058. My Created Wealth = 1431886, Exported = 29462, Imported = 388973. Population = 124 after the migration wave that included the nobles (111 before migration wave). Frond 22:05, 30 January 2008 (EST)

I just got the Tax Collector, Hammerer and Baroness in the year 1056, Mid-Spring Population: 89 Created Wealth: 398852 Imported Wealth 195743 Exported Wealth: 16396 --Gibbonofdoom 10:21, 12 February 2008 (EST)

Another data point. I just got a tax collector, hammerer, and baroness on 12th Slate, 1055, Mid-Spring. Population: 142 Created Wealth: 747376 Imported Wealth: 476282 Exported Wealth: 11560 —MightyMooquack 00:39, 14 April 2008 (EDT)

I added a table above. If you've seen a tax collector appear at lower values, please update. (Maybe this should be on the main page?) --Strangething 18:33, 17 June 2008 (EDT)

I got the Tax Collector, Hammerer, Baron and Baroness Consort at population 86. (But lots of wealth). --AlexChurchill 11:51, 10 July 2008 (EDT)

Has anyone seen the Tax Collector arrive separately from the Baron? I think the Baron, Tax Collector, and Hammerer all have the same conditions. --Strangething 18:18, 8 July 2008 (EDT)

[edit] Labors

What labors will the Tax Collector perform? The first thing my newly-arrived Tax Collector did was "Fill Pond"! Perhaps he's bored because I turned the economy off? -- Raumkraut 14:21, 3 April 2008 (EDT)

"Fill Pond" is a job that any dwarf will do, no matter what labors they have enabled. Other jobs like that are Haul Item to Depot and Pull Lever. Bouchart 21:58, 5 April 2008 (EDT)
