Imperator Rome Magna Graecia Dlc Archimedes Update Religion Guide Holy Sites, Pantheons

Imperator: Rome‘s Magna Graecia content pack adds a lot of objectives and mechanics for long-time fans to try out. This also goes hand-in-hand with patch 1.4, the Archimedes free update, which is free to all players. Here’s our mini-guide to help you out with your nation’s religion, pantheon, and holy sites.

Note: With regards to Magna Graecia‘s focus on the expansion of Athens, Sparta, and Syracuse, you can read our Greek missions guide. For more information about Imperator: Rome, you can check out our guides and features hub.

Imperator: Rome – Magna Graecia and Archimedes religion guide

As mentioned in our preview article, Imperator: Rome‘s Magna Graecia DLC and Archimedes free update have many new features for players to sink their teeth into. Unfortunately, there are also a number of shortcomings whether it’s the opaque UI or how mechanics don’t mesh well together.

Given these concerns, this guide aims to provide an outline of what you can expect from the religion system overhaul. Likewise, while some fixtures such as gods and goddesses and holy sites are generated by events, missions, or apotheosis, we simply look at the ones present once you start your Imperator: Rome campaign. Of course, the means of adaptation and end results will still depend on the player’s choices. For beginners, we also advise you to check out our “Things to do before you unpause” article to get a gist of the basics.

Religion: The Hellenic Pantheon

All pantheons in Imperator: Rome represent the four cornerstones of your fledgling empire: war, culture, economy, and fertility. Specific deities may be assigned to each. They provide a passive buff (P) and an active buff (A) that’s initiated when you call down an omen. For now, we’ll focus on the Hellenic Pantheon for the three featured Greek nations in the Magna Graecia DLC.


  • Athena Nikopheros (Syracuse start) – monthly military experience (P); morale of armies (A)

Irmg Rel Apotheosis Deification

Apotheosis: The deification of your ruler

Imperator: Rome‘s greatest rulers can attain godhood by way of Magna Graecia‘s apotheosis mechanic. Here are the requirements:

  • Have 200 political influence to spare.
  • Your ruler has to have a popularity of 90 or higher.
  • Your ruler’s family must have 800 prestige or higher.
  • The form of government that your nation has must not be a republic that doesn’t focus on theocracies. For instance, since Sparta is a monarchy, you’re able to deify your ruler if you’ve met the other requirements.

Holy sites

Many holy sites exist already once you start your Imperator: Rome campaign and you can see these if you switch to the religion map mode. Should your chosen faction already control one, then you’ll see a slight increase to a deity’s passive and active buffs.

Holy sites can also have sacred treasures/holy relics “socketed” to give extra boons. The number is dependent on the settlement’s level. Now, if you’re in control of a settlement with a holy site, you can choose to desecrate/destroy it so your faction can obtain these treasures. Desecrating a holy site is the only way to “unequip” your own treasures if you somehow made a mistake. This is not advisable since rededicating another holy site can be costly.

Note: Holy sites are specific to a being’s name, including their epithet, even if they’re the same god or goddess. As such, a holy site dedicated to “Athena” does nothing for “Athena Promachos” or “Athena Parthenos.” The same applies to “Zeus” versus “Jupiter.”

Building a holy site

You can build a holy site dedicated to any deity as long as no other holy sites exist for that divine being. You may need to desecrate existing ones in faraway lands if you wish to create these in nearby territories.

In any case, just click on any owned settlement and mouse over the obelisk icon (seen below). This will set you back 400 gold and 100 political influence, but the construction will be instant.
