Artifacts allow you to upgrade using diamonds and gold. There are 7 artifacts. Diamonds used to upgrade artifacts will be added to your blessed diamonds. All upgrades are permanent.
Glove of Zeus[]
Available only in rage mode. Your champion auto-clicks the stone with this artifact. You may activate or deactivate it anytime it is available.
The game has a limit on the number of clicks it will register every second of 25. With maxed glove it is more than possible to hit that limit with manual clicking on top.
Staff of Artemis[]
Available in energy mode and mana mode. Your champion can auto-cast their abilities using this artifact. You may activate or deactivate it anytime it is available. The level 5 upgrade unlocks the energy mode option of this artifact. Before this option unlocked you will not be able to auto-cast energy skills.
Boots of Hermes[]
Using these boots allows your soldiers to return faster in raids.
Ring of Athena[]
This artifact increases your maximum mana.
Clock of Morpheus[]
This artifact increases your offline earnings (gold & knowledge).
Helmet of Apollo[]
Apollo blesses you for increased gold and knowledge for 12 hours each time you login to supervise your kingdom. This effect continues when offline.
Necklace of Hera[]
This artifact decreases your university research time.
Ancient Artifacts[]
Ancient artifacts were added in version 5.2.0. These can be earned only during events but they persist forever. Ancient artifacts increase your building profit, knowledge gains, critical chance, mana per second, rage per click, energy per tick, and War Outpost Army production.
During events you also earn orbs as you progress. These carry through events. For every 20 orbs owned you gain 10% to both Building Profit and War Outpost Army Production. This is applied additively to your total given to you by your AAs. eg. 1 AA + 40 orbs = Total Building Profit 45%, Total War Outpost Army Production 70%.
