Circle of Power/1.03.24

Temples
Despite having a build cost and build time, the Circle of Power is purely a summoned building - one created through the use of the Summoning Magic sphere. The designed purpose of the Circle of Power is to improve the EXP or / and the quantity of units summoned by the owner if he is nearby. (If the Circle of Power is within that Hero's command radius) This is mostly useful for summoning workers for mines (Quasits) as you can summon more with each spell than you normally would. The building is weak and will eventually disappear on its own accord, so once you have it in play, then you best make the most of it then and there. As such, it's usually better to wait until your Hero has plenty of mana - to create the Circle of Power and then spam summoning spells. However, another trait of the Circle of Power is that units will be summoned through it and not your Hero. This does mean you can cunningly create the Circle of Power within a blind spot of an enemy base and then summon an army within! The Circle of Power only affects summoning spells through the Summoning sphere.

Trivia
