[bug 0.75] Can't build cleric in city without essences.

There is a typo in the description as you can see in the xml you have a double period

<Description>Cleric's provide healing and aid to the city's inhabitants.  They reduce unrest in the city and improve your Fame..</Description>

I don;t think .80 is released yet.

You can edit the title of your post so it doesn't show up as 0.80 anymore.  Although, I don't see it on the 0.80 changelog, so your current title is probably still accurate.

It is working as designed.  Clerics are only buildable in cities with Essence, even with the flat unrest modifier.

Can it be added to the description?  Otherwise, people new to the game are going to be very confused.  There's already enough stuff to confuse them.  Maybe also add something to the flavor text.  "Cleric's channel the essence of the city to provide healing..."

Actually, maybe add the requirement to all descriptions  You've got Provides now, then under that you could add Requires or Upgrades From.  That would help people learn the game and also help them understand why they can build an improvement in one city and not another, or why they can't manually place an improvement (because it's an upgrade).  One of the biggest challenges for new players to overcome is simply learning the game, and the existing documentation doesn't help too much.

Yep, good suggestion.

Thanks for info. Would be nice to have this info in building description.

OK, so if settlement builds the essence pool building, does that then allow a cleric to be added?

Yes, I've built the scrying pool in a town with no essence and the cleric became available.

My experience as well.

I had this issue a while back with Conclaves. Confused me, too. Thankfully Derek chimed in (like in this thread). Would be nice to have the improvement shaded out with the reason it can't be built.
