Feeder
Using the ability of Hydarian Crystals to concentrate psy energy, the tosses have learned to feed the obelisks from them.
Increases the number of obelisks available for building. The maximum number of obelisks is the sum of levels with order.
With each level multiplicatively reduces energy consumption of defense structures by a percentage equal to level (or doubled level with x2 order active).

For example, at level 3 energy consumption will be reduced to 99%*98%*97% = 94.1%. With x2 order it will be reduced to 98%*96%*94% = 88.4%.
After level 2, it is possible to give x2 order.
