How may I set my people's holy resource ?

[Jean-Mi Wan]

I din't find any clue in the help windows, neither in the tutorials, nor in the game manual.
I'm stuck in a quest where I must build some structure needing a pack of holy resource... I've got plenty of strategic resources, luxury resources, even pearls, but not any single holy resource.
Please help !

Hover over the strategic ressources to the top left in main screen. It should show you what kind of boni you get from. To activate a strategic gessource as "holy ressource", click on it. The ressource costs to activate this kind of booster raise by city numbers. You can activate the holy ressource boost multiple times. It's duration stacks this way. The duration of the holy ressource effect depends on chosen game speed. For to switch a holy ressource (i.e. from titanium to glassteel booster), the duration of the previous chosen holy ressource effect has to be timed out.

P.S. If I remember correctly, you can activate holy ressource in winter only ?! F**k, it's a long time ago, I played Endless Legend.

A useful link to Vaulters (or Mezari) guide is this one:

Vaulters/Mezari gain the ability to activate any strategic resource like a luxury booster. (No other faction gets this UI tweak.) The cost is also the same as for a luxury booster, i.e. 5 * (#cities + 1). As your empire gets bigger, the cost goes up. (You can game this in the usual way, by activating a new holy resource just before you capture or settle some regions.)

Your strategics that meet or exceed the cost threshold are shown with a box border, exactly as for luxury boosters. To set a strategic as your holy resource, just activate it once (by clicking on it). Then it's your holy resource "forever", until you activate a different one.

The booster-like benefit it gives has a 10-turn countdown, just like a luxury booster. But it remains your holy resource even after that countdown ends, for purposes of Technolover bonus and all improvements that require a holy resource cost, until you activate something else.

Also, during the 10-turn countdown, you can teleport your armies from city to city, for free (except it uses up all MPs for each teleporting army). Sometimes in midgame, you grit your teeth and pay 40 Glassteel you can't really afford, just to enable teleporting so you can dogpile your next victim. (After dogpiling, your next activation will cost 80 holy :)

When playing againstVaulter/Mezari, beat their invasions on the beach and don't let them capture any 1 region on your continent, or they'll promptly teleport their entire backfield in, and you'll never dig them out.

I'm not sure that's an answer to my question...
Does that mean that any strategic or luxury resource is a holy resource during the time it is used as a booster ?
I read somewhere that one resource must be chosen as a holy resource (to build very specific strucures I have still to do research for) but nothing more. I'm not fond of losing a lot of turns researching for structures I won't be able to build.

Strategic ressources, only. Not luxury ressources. And yeah, once activated any of the strategic ressources, it is your holy ressource, as long as you don't choose another one.

[Jean-Mi Wan]

Yes, I figured it now. As soon as I activate a booster, the corresponding resource becomes holy if it's a strategic resource.
Thanks a lot, Groo and Gilmoy !
