Central Tower
The second most important part of the battlefield, the central pillar acts as the dividing line between one army and the other. When a unit from one army crosses it, they will begin charging the pillar until the red bar fully reaches the end, giving their army twenty gold every few seconds. If tower spawn is researched, it will spawn a Spearton/Juggerknight (level 1) or an enslaved giant/chaos Giant (level 2) as well as the gold. Just remember that a unit has to be nearby to charge it and once it' s fully charged, it will continue to produce gold and ghosts without supervision, though it's better to secure the position with miner walls and guards instead. But you can't get miner walls near that thing...
