Covert Operations (Espionage, Sabotage, Assasinations, Theft)
Here is what I was thinking. I always liked how in games like Master of Orion you where able to use spies in order to steal or sabotage your enemy's civ. Here is how I think this could be adapted to Elemental.
We know that we will have heroes and that said heroes can be assigned quests. My own speculation is that some quests you can send your here off to would usually yield some sort of magical <something>. I was thinking you should also be able to assign your heroes with more practical quests. I also assume that the game will have a fog of war as you play.
Espionage: These assignments will range from observing troop movements (basically gaining line on sight on enemy territory) to watching what your opponents is currently building, producing or if they have gained any special or unique items. This could be implemented as a quest in which your hero 'sneaks' into enemy turf and bribes, blackmails or otherwise compromises a unit or building (even the keep) which in turns hands the information over to you. Or you could try to build a concealed observation post which can observe an enemy city or marching army. The quality or level of your 'spy' or 'observation post' determines how accurate your intel is. For example a 'high level' observation post will be able to tell you how many troops of which kind and what quality are making up a marching army. A 'low level' one might just give you an estimate.
Sabotage: This is all about making a mess out of your opponent’s tidy operations. Heroes sent on quests like these could try burn down a building (example the warehouse that has kept your opponent producing units rapidly). Disrupt gathering resources or trade. Poison troops on the field (that could weaken them or outright kill them before a battle) or destroy siege equipment or supplies.
Assassinations: Now the first instinct that everyone has on this one would be a quest to kill your opponent’s avatar which of course would yield a game win. If they allow this type of quest it would have to be very unlikely to succed unless you commit your own avatar to the mission. Sovereign’s aside there a plenty of other targets you could send your heroes on. Killing worker units on the field. Killing the trainers at the academy (affecting troop quality or production time). Of course covert missions to kill enemy heroes. Just think of a general who has beaten your forces at will who is suddenly killed in his sleep (troop morale or xp penalty for a few turns?).
Theft: Your opponents has found <insert uber magical item here>. Well send your heroes to try to go in and retrieve it for your cause. You could also try to steal knowledge such as spells or technology (like steal making methods).
Couterspying: This one is straight forward this one assigns places your here in charge of internal security. This should increase your overall chance of busting an enemy op or flushing out an enemy agent.
I also assume that each mission will have an amount of risk for your hero. In which case he does run the change of being captured or killed. Say the mighty general is a light sleeper and your hero finds himself in the dungeon getting tortured for info....
