Carved from the husk of an ancient Ironwood tree, the Troll Lumber Mill is a vital part of the Horde's lumber processing operation. The Trolls, having lived in the forests of the far north for centuries, have devised a unique method of harvesting. By treating a group of trees with a volatile alchemical solvent, the Trolls can deaden and weaken large sections of wood. Though it is extremely hazardous to Peon and earth alike, this site makes the process of cutting lumber more efficient. Trolls have become quite adept at fashioning a special sort of throwing axe. The crafting and use of this weapon is always being honed to perfection. Troll Berserkers frequent the Ironwood trees to digest potions given to them by the Goblin Alchemists stationed there. These potions enable them to throw their axes greater distances or sharpen their sight. It is also said that the speed at which healing occurs is increased if the correct potion is ingested. This process of regeneration is one of the most distinct and unbelievable powers of the Troll Berserkers.[1]
If you own at least one Troll Lumber Mill, an additional 25 lumber will be added to your stockpile every time a Peon drops off harvested lumber. Peons can also drop off lumber here instead of the Great Hall.
In scenarios where you control both Horde and Alliance units, researching an upgrade here will also grant you the equivalent Alliance upgrade. If you research Regeneration, Elven Rangers will receive Marksmanship instead (though it will cost 3000 gold instead of 2500).
The heroes Alleria and Zuljin will benefit from weapon upgrades, but not Berserker upgrades, researched here.
