Entangled gold mine

Entangled gold mines are units created using the Night Elf building Tree of Life and its upgraded forms. This was not a building nor really a unit, as it was not build by wisps but created by an ability of the Tree of Life that trapped a gold mine in roots. This entanglement allows the Tree of Life to collect gold from it automatically, without assigning units to mine. In order for another player to mine gold from it, however, they either had to destroy the roots or the Tree of Life itself, giving the mine some degree of protection.
