it also depends on location.. i found hp and mana seem to regen (and faster) when you are in your controlled territory or inside your cities respectively.

If you can get a champ with that ability; I wouldn't complain. lol

Some monsters are also able to regen. Interestingly enough, the higher level of the spouse when you first get them to join your faction, the higher the regen seems to be.

I often find that if I marry the first person I find, they're usually of an inferior quality and produce inferior children, but if I spend the time looking for a good spouse, the results are much much better. Take it for what you will.

I found that if I wait till after i research the medic pack, equip one to my expected wife, with all else she can carry as well as myself, then wed.. all offspring get regen powers base from equipment

I suspect its an unintended effect as equipment should not translate into hereditary traits.. But then I also got a son Level 1 with 95 essence to start.. not sure how that worked out except that my capital has the + 25% essence feature in it.

My grand kids have it and my kids have it with out using medic pack..

ayup not sure why just know it happens.. I am sure we shall get some elucidation or input from powers that be this coming week..

For some reason, your and other sovereigns' offsprings always get the talents "regeneration" and "clarity".

If you want your sovereign to have that too, you have to mod him/her before starting the game, since there are no in-game options to catch up on that later, at least none that I am aware of right now.
