Overview
Retribution is one of the most reworked specs in WoW Forever: a new tree, new abilities and revised old ones. You no longer just auto attack: 
Holy Strike, 
Judgement and your seals form a real rotation.
The final talent, 
Twist of Light, lowers the cost of your seals. When you replace one seal with another, the old one leaves an echo that applies to your next swing: that swing benefits from both seals. It is simplified seal play, made easier to read by the game’s swing timer.
Your group role mixes decent damage with a lot of utility: blessings, auras, dispels. The spec is easy to pick up at low level and gets a little more involved later. At level 20 in the beta, it sits in A tier among DPS and is seen as too strong.

Read the details
You handle one target as well as a pack, and you bring blessings, auras and dispels to the group. 
Blessing of Freedom and 
Cleanse free you from slows, while 
Lay on Hands and 
Blessing of Protection save a bad situation.
On the other hand, you have no big damage ability on a cooldown. Your mana pool is small, your power depends on the spell power of your gear, and you have to switch specs to tank or heal well.
Key spells
Key talents
Divine Strength and 
Improved Seals (Holy tree)The level 20 foundation, with +15% damage on your seals and judgements.- 6 sec of immunity to silence and interrupts.
Benediction (5 ranks)-10% mana on your instant spells and abilities. This is what fixes your mana trouble beyond level 20.- +5% melee crit.
- Your Judgement refunds 60% of the judged seal’s cost.
- +20% Holy Strike damage.
- Your spells gain damage and healing based on your Intellect.
- Twist of Light at the bottom of the tree.
Seal of Command is not clearly better than Seal of Righteousness once the latter is improved by talents and backed by your spell power.
Rotation and priorities
Single target:
Priority 1:Seal of the CrusaderFor a first Judgement: the target takes more Holy damage.When: Long-lived target
Multiple targets: 
Consecration on packs. On a single target, it is not worth its mana cost.
Stats
- 1Spell power
- then 2Strength
- then 3Critical strike
- 1 Spell power
- from your gear
Order to be confirmed: the exact priority is not settled yet.
For now, Retribution relies on spell power from gear, then Strength and crit. The exact order is still to be confirmed. Weapons rich in spell power seem to reduce melee damage by about 25%, also to be confirmed.
Leveling
At level 20, put your 11 points into Holy: Divine Strength 5/5, Improved Seals 3/3, 
Divine Intellect 2/5 and 
Voice of Truth. Retribution points come after.
Before Benediction, watch your mana around levels 13 to 16: drink between fights and avoid chaining packs. In dungeons, use Cleanse, Blessing of Freedom and Blessing of Protection: your utility is your strength. Shadowfang Keep, The Deadmines, the Ruins of Lordaeron, Wailing Caverns and The Hall of Thanes have pieces for you.
