Night Elf workers, called Wisps, want to Wow gold classic Entangle a Gold Mine to collect from it, which requires 60 minutes. Once built, Wisps can be'loaded' into the mine, gathering gold without needing to move. Being the ecological sort, they also don't destroy trees while gathering lumber, similar to the other factions. Pop a wisp onto a tree, and it is going to float around gathering lumber for the remainder of the match.
The Undead also have a special gold structure -- a Haunted Gold Mine. Much like Night Elf Wisps, Undead Acolytes remain about the mine and collect mechanically. At 100 seconds, construction one is slower compared to the Entangled Gold Mine, however, Undead Acolytes don't have to stick around in 1 place to build, instead summoning a portal that attracts their constructions into existence.
Undead also differ in the other factions in that they need to use their simplest combat unit -- Ghouls -- to gather lumber. They're also much more defensible, if your competitor target your workers.
All games begin with your starting town right next to a gold mine. Night Elf or Undead players may find their starting mine prepared to use, will not need to worry about Haunting or Entangling immediately, before,the very first Gold Mine collapses. That's right, Gold Mines don't last forever, so you'll be seeking to expand rapidly into the early mid-game. Locate another gold mine and begin planning to clear the region and expand to a second base. You also want to watch for your opponent's expansions. If you have two gold mines, and they've just got one, you're going to be in a critical benefit.
To find out where your opponents are enlarging too, though, you will want to devote a while on recon. Sending a beginning worker out to learn more about the map is a common tactic, but make sure you replace them quickly to avoid losing out on precious early game resources. As an example, all factions have access to flying or invisible units which make for good scouts. Finding out early what sort of cheap classic gold force your competitors are building allows to construct an effective counter force. Check the section on'Creeping' below to find out more about neutral buildings, and a number of the great scouts you can hire there.
