Backslots
There are 2 versions of back slots: Quivers, which have an offensive infusion slot, and Books, which have a defensive infusion slot.
The basic recipe
250 Teir 6 fine crafting material
1 Vial of Condensed Mists Essence
50 Globs of Ectoplasm
24 skill points
The skill points item determines whether you get a Quiver or a Book. 24 skill points worth of Philosopher stones will make a Quiver, 24 skill points worth of Crystals will make a book.
There are 5 different variations of the back item, corresponding to 5 of the Tier 6 crafting materials. Totems, Venom Sacs, Karka Shells, and Dust do not have a recipe.

Infused Back Slot
Once you've created a backslot item, you can infuse it. Infusing the back slot is expensive, and adds a built in +5 Agony resistance.

The recipe to infuse a back slot is:
Base back slot item
Glob of Coagulated Mists Essence
250 Globs of Ectoplasm
Gift of Ascension

Rings
There currently isn't a lot known about ascended rings. What we do know is that you have a chance of getting an ascended ring from the daily chest (mini chest that appears above your minimap) at the end of fractal difficulty 10+ (aka Tier 2). More info in speculation section below.

Infusions
There are 2 basic infusions that you can purchase inside the fractals, a defensive Simple infusion costs 75 fractal relics and grants +5 Agony resistance, and a Versatile Simple Infusion costs 225 fractal relics and can be used in offensive or defensive slots.

Additional Infusions can be crafted with the following recipe:
250 Karka Shells
100 Tier 6 Crafting Material
20 Mystic Coins
Eldritch Scroll

Offensive Infusions have +5 to an offensive stat in addition to the +5 agony resistance.
Malign Infusion +5 Condition Damage
Mighty Infusion +5 Power
Precise Infusion +5 Precision

Defensive Infusions have +5 to a defensive stat in addition to the +5 agony resistance.
Resilient Infusion +5 Toughness
Healing Infusion +5 Healing
Soothing Infusion +2% Agony Duration Reduction
Bounteous Infusion +1% Boon Duration
Vital Infusion +5 Vitality
Simple Infusion (Only +5 Agony Resistance)

All infusions have a normal version, and a versatile version. The versatile version can be used in offensive or defensive slots, wheras the normal version can only be used in that specific type of infusion slot.

I'm not 100% on the above breakdown of which ones count as offensive and which ones count as defensive
Fractal Weapon Skins
These aren't directly related to ascended gear, but you get them as random drops in tier 3+ (Difficulty 20+). They are account bound so if you get a skin you can't use you can transfer it to another character you own, but you can't sell them or trade them.

Agony
Agony is a debuff that isn't a condition (can't be removed by condition removal) that ticks away percentages of your health. Agony first shows up in tier 2 (10+) from special boss moves. With no agony resistance each tick will remove 1/8 (12.5%) of your health. Having just 5 agony resistance will cut that damage hit in half to 1/16 (6.25%).
I am unsure if agony hits harder in higher tiers, thus necessitating more and more agony resistance.

Speculation
I believe the Shards of Crystallized Mists Essence (possible drop in tier 3, or combined using 5 tier 2 or 25 tier 1 mists essences) are the key to creating versatile infusions, and to infusing the basic rings that you can get as drops.
I have a feeling there are more recipes that use the Glob of Coagulated Mists Essence than the 2 that we have found.
I assume that the Prototype Fractal Capacitor that can be purchased using Fractal Relics can be infused in the same manner as the 10 other back slot items, but I haven't seen any hard evidence to prove this.

Tertiary Info
Fractals are seperated into tiers. 1-9 is Tier 1, nothing causes agony, no significant upscaling of mobs, vials of essence can drop. 10-19 is tier 2, bosses cause agony, globs of essence can drop, daily chest can give you a ring. 20-29 is tier 3, more agony causing effects, mobs have additional abilities, Fractal weapons can drop. I don't know of anyone that has made it to tier 4.

There is a daily reward completion for each tier. Each tier has a different subset of possible rewards. I recommend at least doing the tier 2 (difficulty 10) daily each day as it has a chance to give you an Ascended ring.
Closing

Any additional info (or corrections) are gladly welcomed. If you don't feel comfortable editing the wiki (I'm pretty terrible at it myself...) feel free to post info here and I'll get it in there.

This is a community effort, I don't take credit for discovering any of this stuff, I just compiled it.
