Thor is the Norse god of thunder and the son of Odin All-Father, ruler of Asgard. He wields the mystic hammer Mjolnir, which allows him to fly and fire bolts of lightning.Marvel Source
Thor was a founding member of the Avengers and frequently battles as one of their number. At times, Thor has used the secret identity of Donald Blake to walk among mortals, but he always returns to the halls of Asgard to hoist a tankard with his fellow gods.

1-1 SKILLS YOU SHOULD (MAY) MAX
Storm Strike - Storm Strike is still my favourite basic skill because it has a good AOE damage, trigger the bonuses from Idol of Khonshu and Uniques (that's over 2000 damage rating), and surprisingly better single target damage than Thundering Strike (may subject to change.)
Anti-Force, previously known as God Blast - The cool-down may be higher now, but the damage has been increased. You may not need it to kill trash anymore because Storm Strike will do the job. Nevertheless, it still has good AOE range and may do well against boss with the damage it has now. You just have to put Anti-Force in your rotation. Remember to click that button every 10 seconds when you fight boss. Did I mention it is good at PVP?
Immortal Combat - Wonderful passive for Melee. It adds damage rating to all melee powers and add defense and tenacity rating when you use a melee power.
Asgardian Stamina - A defensive passive that add maximum health, defense rating, life regenerate and chance to ignore projectiles (added in Patch 2.1).
Warrior Madness, previously known as Asgardian Frenzy - It may not be as good as before, but a damage and defensive buffs 50% of the time may not be a bad idea (15 seconds activation with 30 seconds cool down at rank 40). Note that you still get the 2640 defense bonus, 525 life on hit, 20.6% attack and move speed at rank 40 when you activate it at full health. If you activate it at low health(hint: PVP), you get the above bonus and a damage buff to ALL damage including Anti-Force.Works well with a medkit core. (Read the core section for more details.) Besides, Thor's chest unique adds a total of 13 skill points to the skill. Seems like a waste not to use it.
1-2 ONE POINT WONDER
Aesir's Boon - Shake off negative conditions affecting you.
Thunderous Charge - Thor gets this immediately at level one in patch 2.1, so you don't even have to spend point on it. With + Son of Asgard and + all skills from your gears, it should be good enough.
Hammer Smash - Thor also gets this immediately at level one in patch 2.1. A long knockdown duration with enemy weaken power that added in patch 2.1. A good skill to keep on your bar for emergency situation.
1-3 PREVIOUS SKILL THAT MAY NO LONGER USEFUL
Crushing Hammer, previously known as Hammer Punch - It still do decent damage against boss, but most people use it because of the Physical Damage life steal from Frenzy. Without the life steal from Frenzy, it may not worth your 20 skill points.
1-4 WHICH LEAVE YOU 30 SKILL POINTS
This is where the fun begins. With most skills buffed in patch 2.1. We can finally build Thor based on our play style.
Here are some good choices:
Almighty Mjolnir - Hey, Thor doesn't feel like Thor if he has no hammer throw skill. Besides, there is no longer a 1 second minimum charge time. You can spam it if you like.
Asgardian Smite - A good skill to start a fight. It will make sure you tap all the enemies to get the experience and rewards for legendary quests.
Bring the Thunder - Remember the time we spam BtT over and over again? With the damage buff and a good 5 seconds duration, it is worth to give this skill a second look. It also works well in melee range when you cast it on the enemy while you smash your enemy with your hammer.
Crushing Hammer - Seems like some people still like this single target spirit spender. At least the attack speed has buffed significantly in Patch 2.1 which is good for life on hit.
Hammer Smash - Who said you can't max Hammer Smash? The higher rank, the higher damage and longer knockdown duration.
Hammer Strike/Thundering Strike - A good alternative for single target skill because it's spirit free.
Storm Hammer - This skill is good in PVP because it is one of the rare spirit spender that has no cooldown in PVP.
Whirling Hammer Defense - Without Frenzy, Thor may not able to tank bosses as good as it used to be. So, one point into Whirling Hammer Defense may not be too bad after all.
It really depends on your play style. The build here is my personal favourite.
2. MEDALLION
My current choices are
Taskmaster - Thor has been known as "good at everything best at nothing" in this game. So, might as well be that good at everything guy.
Dr Doom - We want that +power duration to keep our Warrior Madness up.
MODOK - This should give you the best TTK for single target with the taunt.
Doc Ock - This is your PVP medallion. Insane range with Anti-Force and you will need that +critical chance for area damage now.
Some other choices are Tombstone, Blob, Mandarin, and Kingpin.
3. ARTIFACTS/BLESSINGS
Note: Blessings can be stacked. You can have two of the same kind.
Some that fits Thor are: Blessing of Odin, Blessing of Hela (added cooldown in patch 2.1) and Blessing of Fandral.
Hand of Doom: Supposed to be the best artifact in the game.
Idol of Khonshu: Your bread and butter for Storm Strike.
Xerogen Crystal: You want that movement speed that gone from Flight and attack speed due to not able to keep Warrior Madness(Frenzy) up all the time now.
Advanced Metasensory Array: Nice DPS boost and + 1 skills.
Some other choices:
Ziggurat of Kargul: Who doesn't like teleport? Good critical chance and damage.
Advanced Starstone Tooth: Nice life heal and little bit of Dodge if you have trouble surviving.
5. UNQIUE

I personally don't like the hammer that much. Some good roll cosmic weapon may be a better choice. The boot may works well in group but a cosmic boot with +5 to any of the skills you use may work better. I use Hercules myself because of the -5% incoming damage. For the helmet, some people may prefer a high roll critical rating and critical damage cosmic helmet. A nice one would be +600 critical rating and +900 critical damage.

6. Patch 2.0 LEGENDARY
I would say Norn Stones, Gungnir and Excalibur (Rank 2 is actually +1000def) fits Thor's play style.
Pick one that fits your play style and gears.

Gungnir is a lot of people's favourite. The 800 critical rating and 2000 critical damage sure looks tempting. Excalibur is good for people who likes to stay in melee range. 800 melee damage rating would increase your dps by a lot. Work well with MODOK or Kingpin medal if you want to be a DPS beast. I chose Norm Stone myself. It's a pure gamble. I am hoping they will do a nice revamp of the attribute system in Jan.

7. RELIC
Being defensive: Relic of Lemuria for life on hit
Being offensive: Relic of Asgard for melee damage.
8. COSTUME AFFIXES AND CORE
Affixes: Health Regen on Enemy Defeat/Health Regen on Basic hit - You may need these more than ever because they tookt he phyiscal damage lifesteal away from Frenzy. Damage Rating
Core: My suggestioin is 0.5% Life steal and +Energy(still looking for one with RiF). Same reason as above, you want that life steal. +Energy because most of Thor's skills in my build has energy damage.
Other option are +25%health/spirit or become invulnerable for 2 seconds. Use a medkit right after you use Warrior Madness will let you get the highest damage buff possible (The higher damage for more health missing when activate.)
9. HERO SYNERGIES
Some good ones that will make your Thor more Godly.
Black Panther +3%Move Speed +2%Melee Damage
Cable* +1%Critical Chance +1%Critical Chance
Cyclops* +2%Energy Damage +10%Experience
Daredevil +2%Normal/Elite mob Damage +2%Normal/Elite mob Damage

*What I am using currently.
Note: It really depends which hero you have and enjoy. You are the one who has to level them to 50. Don't do it just because you want the synergy. Do it because you enjoy it.
