Warcraft III: Reign of Chaos/Night Elf buildings

Many of the Night Elf "buildings" are actually intelligent trees, not that it has any effect in the game. Producing any "Ancient" costs one Wisp, so the practical cost is 70 gold more than the list cost. Unique to the Night Elves, harvesting lumber does not use up trees; they can get an infinite amount of lumber from each tree. If you need to eliminate trees, you have to use another method besides harvesting them.
