i am unsure if this is random or pure luck from my part.

but all the children i have gotten so far - all have Regen and mana regen, which is nice - though i would think it could be interesting to see that because of the magical nature of these children - its random powers they get, so that when they are born and you see the little tikes - you also see - "this one has been blessed with great magical skill , or magical strenght flows through this child,  Dont mind the wings my lord, he will be awesome .

this could make for some interesting offspring - and maybe even sometimes you get a (pardon the expresion) Mudblood that simply isent special.

Powers here could be

Uber strenght       : this kid has titan blood in his veins !   +str /+ con
Attuned body        : Mana regen & health regen (low mana income/ low health income)
Magic born           : Mana regen (strong mana income)
 troll heart             : Health regen (Strong health income)
Cursed                 : cause penaties to those he attacks - but he also cause morale drop in a army
One of Earth         : Severly ugly -(no children possible)- Earth spells cheaper by 1 - plus a stat that is releavant to earth (con str def something like that)
One of fire             : Severly ugly -(no children possible)- fire spells cheaper by 1 - plus a stat that is relevant to fire - str - dex - speed
One of Air             : unable to have children (lacking substance) - air spells cheaper - plus a star that is relavant to air - dex speed move
One of ice             : unable to have children (cold shoulder) ice spells cheaper - plus a stat that is relevant to ice - con / int /
One of Life            : (RARE only kingdom) many children - life spells cheaper - )
One of Death        : ( RARE only empire) many children - death spell cheaper - )
Dragon blood        : special attacks - fire breath - increase with level )
Mudblood ()       : can never learn spells
Burning blaze!       : This kid will be powerfull in many things (stats , essence) but his life span is short!
Immortal              : (if aging cause death - he doesent die - and essence can be used to prevent physical death like the sovereign)
Quick learner        : earns xp faster.
True leader           : morale booster - units fight harder in his army
War spirit             : very good with melee weapons and defences.


((here those that are born of one instead of having stat bonuses - they could have increases essence - due to the fact they will never continue the line))

This could also add some fun items to the soverieng - as you could buy (some) of these at start - and make a line of childre that have greater chance at THAT power.

this would give value to the children as some childre are better than others - and making them be married off could have costs - or be cheaper to do since you are introducing a strong bloodline.
