Tree of Pain/1.03

Dark Elf
Tree of Pains produce all Dark Elven units and therefore nearly all units available to the Dark Elf race. This makes the Tree of Pain the common production building, and so it's a good thing that these buildings are about average in size, as you really will be building many of them. They are also cheap and durable, too, with their only sub-par stat being their poor 5 view range - which doesn't even matter. Finally, since all units produced from the Tree of Pain are all 1x1 footprint sized and the building has a very simple shape, you don't even need to put much care into how close you place these buildings together.
