I am trying my luck with "The Nin-In-Eilph". I have to admit, not even easy mode works for me. Either the threat is killing me or I use a "more spirit like deck" but then I get kind of outrun by the enemys.

None of my usual deck seems to work. But I am not sure how to improve...

I need suggestions to build up a deck for single player! Any help, please?

What card pool do you have access too?

mostly all, if I'd proxy.

Solo, two-handed? how do you normally play? What heroes are you currently trying?

Solo. I try every now and then with a(ny) deck which I so have at that time.

I am used to play willpower-heavy decks. This is why most the times I get quite fast into one of the stage 3s (otherwise I get crushed in stage 2). But I am not well-equipped enough to survive there. What me buggs the most; it seems there are no special dificulties at that mission, except the extras from the quest cards.

So my guess would be that I need a more leadership/tactics deck or something which can withstand/survice longer on a spot - anyhow, I think I suck at building non-spirit-ish decks....

It's been awhile since I've played that quest so I don't really remember what tricks it has, but for Solo I'd try Elladan, Elrohir and Arwen. Steward and Gondorian Shield on Elrohir, Horn on Arwen, Rivendell Blade/Elven Spear and Light of Val on Elladan. Use Arwen and Errand-rider to smooth any resource issues. Unexpected Courage on Elrohir & Elladan.

Nin-in-Eilph kind of requires you to be good at everything - you need to be able to quest well to progress and you need to be able to combat well, because leaving enemies in play will mess you up with their forced effects and hanging around too long will drive your threat up to unmanageable levels. I find the passive effects on the stage 2 quests to be worse than the ones on the stage 3 quests, but stage 3 has the Ancient Marsh-dweller hanging around being a nuisance in staging or murdering your allies.

Playing pure solo it's obviously more difficult to strike that balance between having good willpower and good combat than in multiplayer, but on the other hand only one card of staging means things are less likely to spiral out of control and destroy you with all the negatives from the locations sitting in the staging area. Location control can still be helpful though, and it may remain useful to try and not rely on item attachments given the presence of Sinking Bogs.

A handy nuance to realise is that although I said you need to be good at combat, really you only need to be particularly good at attack. The direct damage and extra attacks can be horrible if you keep the enemies engaged with you, but if you just defend them once and then kill them, they're 1 attack and 3 attack, neither of which is that big a deal. Meanwhile the Ancient Marsh-dweller you probably want to chump block regardless since it starts at 6 and then gets steadily worse. If you can kill enemies as they pop up, I'd say with only the one encounter card per round it's not so bad to wait around a little building up your board state before advancing - apart from the threat gains.

So my advice based on all this would be to have a setup which can fairly quickly get up to 9 attack - meshing this with good questing means versatile heroes with readying effects may be a good idea - and bring threat reduction. Hang around a little building up to the point where you can deal with the Ancient Marsh-dweller, then try and smash through fast once you're ready.

Personally, until reading this thread 2 days ago I'd never done Nin-in-Eilph solo, but then to figure out some decent advice I tried and beat it using one of the decks I used to beat it two handed - a location control deck with Idraen, Glorfindel and Loragorn. So with Light of Valinor, Wingfoot/Unexpected Courage and exploring a location I could have 9 attack ready for combat, good willpower, Asfaloth for that bit of extra progress and Loragorn of course solves all threat problems.

Hope some of this rambling is some help!
