All right, starting with the Dwarves (and the Rings!)

(The Ruling Ring is 18 C 1)

•The One Ring, Hidden in Shadow [ring]
Vitality: +1
Resistance: +1
While wearing the One Ring, bearer is strength +1 for each twilight token you can spot (limit +4) and each time he or she is about to take a wound, add a burden instead.
Skirmish: Add a burden to make the Ring-bearer put on the One Ring until the Regroup phase.
18 R 2

I’d drop the Vitality bonus and make it resistance +2.

•Balin’s Halls
Condition • Support Area
Skirmish: Discard this condition to make a companion strength +2 for each underground site in the current region.
18 R 3

Very balanced. Nice job!

Power of the Rings
Event • Fellowship
Exert a companion to draw a card for each artifact you can spot.
18 R 4

Maybe put a limit on it, with all the artifacts you’ll be adding in this set.

•The Arkenstone, Warning-Beacon
Artifact • Support Area
Fellowship: Add 3 threats (or exert a Dwarf and discard this artifact) to reveal the top ten cards of a Shadow player’s draw deck. You may discard a minion revealed for each other artifact you can spot.
18 R 5

Just a couple of gramatical errors. "...of an opponent’s draw deck..." and "...discard a minion revealed for every 2 artifacts you can spot...".

Desire for Mithril
Condition
Resistance: -1
Bearer must be a Dwarf. Each time bearer wins a skirmish, you may exert him or her to take the bottom card of your draw deck into hand.
18 R 6

This seems more like an Elven telepathy card, but hey whatever works. You could probably drop the cost to 1 and remove the resistance downer.

Treasure in the Depths
Event • Regroup
Exert a companion bearing a condition to draw a card.
18 R 7

Read Delving. It’s a common.

•Balin, Lord of Moria
Companion • Dwarf
Strength: 5
Vitality: 3
Resistance: 6
Balin is damage +1 for each underground site in the current region.
Skirmish: If Balin is damage +X and not assigned to a skirmish, exert him to make a Dwarf strength +X.
18 R 8

Hmm...I think he should be stronger.

•Dain Ironfoot, King of the Lonely Mountain
Companion • Dwarf
Strength: 7
Vitality: 3
Resistance: (5)
While Dain is the Ring-bearer, at the start of each skirmish involving him, discard two cards from hand or add two burdens.
Dain is Resistance +1 for each underground site on the Site Path.
Fellowship: Exert Dain and add a threat to play a artifact from your draw deck.
18 R 9

I like him but his Ringed Resistance should be lower. Maybe 3?

•Gimli, Lover of Deep Places
Companion • Dwarf
Strength: 6
Vitality: 3
Resistance: 6
Damage +1. While you can spot another companion, Gimli is hunter X, where X is the number of underground sites in the current region.
18 R 10

Good job.

Forged From Mithril
Event • Response
If a companion bearing armor is about to take a wound in a skirmish, add a threat and exert the Ring-bearer to prevent that.

I like it, although the cost could be 0.

Also, your cards aren’t in alphabetical order.

I’ll finish up the Dwarves later...review these!
