I would definitely like opinions on this one, as the scenario will be a little hard to figure out.  The reason I made him so vulnerable to damage is because I don't want him to stay in play for too long, or he'll become overpowered.  But the damage can be easily solved by a Warden of Healing paired with Elrond.

So here are some of the cards that I'm planning to put in the encounter deck if everything turns out alright.  I'm sorry about the white backgrounds, I couldn't find art that I liked that fitted the description of the card.  So for now, we'll have to use our imagination about how the picture looks on the card.  This quest (I'm planning to make a chain of three quests) focuses on your party journeying to the east in hunt for the Blue Wizards.  But the Easterlings are very numerous, and they plan to stop you before you get very far.  I really wanted the players to feel the pressure of the enemies and to feel overwhelmed, so there's going to be a lot of Easterlings. 

Sorry that the images are so big, I couldn't figure out how to shrink them.

Interesting!

Ok now some comments:

Wild orc is deadly, if you don't have a feint or cheap first turn soaker. Maybe too deadly if it appears in first two turns (very low engagement cost)) I would make it a little bit bigger, so it would not hit you during the first turn… But nice little enemy indeed :-)

Easterling chieftain: Would it be better if the bonus would go to the easterling enemies only? (a matter of taste) The real problem may be that when this one come to the staging area it will be engaged during the same turn it was released (there is not any rule in the card that would keep it in the staging area) so the +1 effect would never come in use, so it is somewhat empty card at this incarnation. Maybe: "You can not engage Easterling chieftain, if there are other easterling minions in the game…"

Endles plain: this is pure pain… Very dangerous location, but maybe suited to location manipulation and heavy tactic decks. Have to play with it with spesific deck until I can say more, but dangerous location indeed!

Easterling Ambush: A nice card that keeps those easterlings coming. Does not need any tweaking from my point of view…

You seems to focus on minion horde that just keep on coming from the very moment it is released from the enounter deck. These cards support that theme guite well. It allso means that bad start (no allies) will end the game very quicly. A player need a big party of allies to fight these. If he don't get them he will be overwhelmed very quicly. It is a good and a bad thing at the same time. A dwarf ally heavy deck can manage this, but not so many other deck type at this moment. Interesting to see how those new Gondor cards will do against this. Not a easy encounter deck type to balance.

(edit) see the post below

Thanks for the comments! 

Wild Orc: I made this guy so hard because he's supposed to be a rampaging orc, and he wouldn't really care what your threat was before he started attacking.  But I might make him less harsh on the engagement cost after playing with him in the scenario a few times… Maybe a 27 or something.

Easterling Chieftain: The main reason for this guy's forced ability has to do with his shadow effect.  If you happen to draw him regularly, then he won't be too much of a problem other than his high stats, but if you draw him as a shadow card, then all the enemies get +1 attack, which could prove deadly.  But yes, I meant for his ability to be for only Easterling enemies, so I'll change that. 

Endless Plains: I agree that this one is very difficult.  I will fear it every time it pops up.  But if you're on an open plain, then your enemies are going to have a big advantage to you because they can see you and attack you better.  Still, I think after a few times of playing with it, I'll decide whether it needs something to compensate for it's bad effects, such as more victory points, or maybe a reponse like "After Endless Plains leaves play, all players may draw one card" or  something like that.

The point of this quest isn't really to be able to fight all the enemies.  You pretty much get ambushed, and so you have two options: Run away, or try to fight them.  So I've included a pretty cool effect, where on the second stage of the quest the enemies are gathering together, planning to attack.  But in that same time, you have the option of running away.  The locations that you explore during stage two go into your victory display instead of the discard pile, even if they don't have any victory points.  And then on the last stage, all the enemies attack. But, if you have 5 (not a decided number yet) locations in your victory display, then you've succesfully run away from the enemy without having to fight them. If you don't, then you'll have to fight all the enemies until their are none left in play. The second is harder, but there's a reward at the end of some treasure cards if you go this way…

I'll try to post more cards later.  And maybe you'll see some player cards in there as well to help deal with the so numerous enemies….

Ok. That sounds interesting. So you can manage as long as you can keep alive and explore those locations. Hmmm… Not bad at all! Allso now I got that Easterling chilftain better. The shadow effet is actually good! Have to read these more properly.

Remainds me about a little bit of one of those Hobbit scenarios, but a with a twist. Good job!
