Bless Unleashed

Freysi's guide does a good job explaining how to obtain the other combat blessings, however as a returning player, there are new "Livelihood Blessings" which counted towards this achievement for me, so I thought I'd add these for alternative (and easier) options. Apologies for the wall of text but hopefully I broke it up in a way that is easy for you to find what playstyle fits you.

"Mark of the Wolf," "Lionheart Legacy," and "Crescent Moon" are still your recommended easy story related combat blessings. The Livelihood Blessings below though are smaller blessings for non-combat playstyles so you can pick and choose some easier things to farm.

How to Obtain

Each Livelihood Blessing requires you to complete an in-game trial (achievement) which upon unlocking will send a quest-starting item to your mailbox. Completing all stages of the quest will unlock the blessing. It is possible you already have progress towards these blessings if you've been playing normally.

Touch of Lily'anthes

• Playstyle: Gathering
• Trial: The Giving Nature - Obtain specific crafting materials (see notes)
• Quest: You will have to defeat 3 fairly challenging plant enemies.
• Notes: For the trial you will need to gather the following items: Luminous Roots x30, Thin Branch x30, Unripe Fruit x5. Roots are ground plants, Fruit and Branch come from trees, and all of them drop in Carzacor, Navarra, or the Gnoll Wastes. You might also be allowed to buy them from the auction house but I have not tried this. The trial says "obtain."

Progress can be seen in Trials>Exploration>Other

Touch of Paetion

• Playstyle: Crafting
• Trial: Handiwork - craft 50 items
• Quest: You will play an easy mini-game.
• Notes: An easy way to craft 50 items is to buy 400 stringy meat from a general goods vendor (9,600 gold - 24/per), then use a soul pyre to craft 50 fish baits (8 stringy meat/per). Alternatively there is a lunchbox for only 1 stringy meat/per, but you might find that bait useful for the Syrania blessing. The mini-game has you carry a pot around a track without getting hit and that's all you must do making this arguably the easiest blessing to unlock in the game.

Touch of Baraka

• Playstyle: Animal Taming
• Trial: Can You Hear My Heart - capture 5 animals of any type
• Quest: You will need to tame a Disheartened Blue Wolf.
• Notes: Taming animals requires you to own an estate which you unlock late into the main story. Unless you are already to that point of the game, this blessing may not be the most viable option.

Progress can be seen in Trials>Normal>Capturing Animals

Touch of Syrania

• Playstyle: Fishing
• Trial: Rookie Fisherman - Catch 10 fish over 5cm
• Quest: You will need to catch a Splendid Alfonsino fish.
• Notes: You must unlock fishing to attempt this trial which is a short quest to talk to any fishing vendor. The trial is RNG based but not bad. You need bait to fish. See "Touch of Paetion: notes" for an easy bait method. The quest is also RNG based and unfortunately can be bad. This blessing will be easy or a real pain depending on your luck. It only drops in downstream waters (Carzacor Harbor is a decent spot).

Touch of Teleos

• Playstyle: Potions/Alchemy
• Trial: Alchemy is Fun - create 30 items at an Alchemy Station (aka distilling)
• Quest: You will do some fetch quests to craft a quest item
• Notes: The quickest way to craft 30 alchemy items is to obtain 90 Luminous Roots (plants in Carzacor, Navarra, Gnoll Wastes, or use the auction house) and craft the "Potion of Recovery I" 30 times.

EDIT: Sep '22
To anyone coming new to this game to try to finish it before the shutdown, it's likely that this guide is woefully out of date. I have not continued to play since I wrote the guide. The other guide here by FruitofPassion is probably a better place to start, although I have no idea if things have changed even since then! Good luck to everyone!

EDIT: New update makes BE significantly easier to get, and SC a bit easier. Now only need 1k Warrior Talents for BE, which means if you do all your prestige every week, and one dungeon a day, you should be able to get it in about 5 weeks (3-4 weeks with valor and two dungeons a day). I would also expect the cost of keys to go down, so you could conceivable get BE in a week if you manage to get 60 chests and do your prestige. Invasions are now every 8 hours, so it is now nearly three times easier to gather essences. If you manage to hit every invasion, then it would take 16 days instead of nearly 50 to gather fire and growth. I also expect the prices to drop. All in all, a great update.

There are 7 blessings available to fulfill this achievement:

Mark of the Wolf
Lionheart Legacy
Crescent Moon
Nightwind
Storm Chaser
Blind Executioner
Centurion's Command

During the story, you will unlock the following 3
Mark of the Wolf
Lionheart Legacy
Crescent Moon

That leaves 2 remaining which you must unlock, out of the following four:
Nightwind
Storm Chaser
Blind Executioner
Centurion's Command

Nightwind
For Nightwind you need 5 fragments which drop from various dungeons. These fragments can also be bought on the marketplace. The drop rate for these fragments is abysmal, so if you choose to go for Nightwind, I would recommend simply buying them from the marketplace. The cost for all 5 on Teleos (EU) a month ago was around 500k seeds.

Fragments drop here:
I - Altar of Blood
II - Archon of Fire
III - Crimson Waterfall
IV - Den of the Wolf King
V - Infernal Kitchen

Storm Chaser
For Storm Chaster you need 5 fragments which are bought from the 5 reputation vendors in Ordo, Navarra, Ardell, Tristezza, and Herbati. The cost for each is as follows:

I - Ordo - 300 Ice Essence, 700 Fire Essence
II - Navarra - 300 Light Essence, 700 Growth Essence
III - Ardell - 300 Chaos Essence, 700 Fire Essence
IV - Tristezza - 300 Darkness Essence, 700 Growth Essence
V - Herbati - 500 Growth Essence, 500 Fire Essence

Totals
300 - Dark, Light, Ice, Chaos
1900 - Fire, Growth

Total, 5000 Essences.

These Essences drop from Invasions. They are found on the map and spawn every 22 hours, give or take. Here is the list:
Navarra - Light
Ardell - Fire
Rift - Darkness
Alicorno - Growth
South Sperios - Fire
North Sperios - Ice
Padana - Growth
Rutus Road - Chaos
Zenkala - Volcanic Wyvern - Light
Timeless Jungle - Swamp - Darkness (thanks Achievement)

How to spawn the invasions:
Navarra - Kill a bunch of the wild bulls
Ardell - Kill a bunch of pumas across all channels
Rift - Kill 6 cyclops
Alicorno - Spawns directly at the stone
South Sperios - kill a bunch of Footpads
North Sperios - kill a bunch of Footpads
Padana - Kill enemis in the area
Rutus Road - Activate, and then immediately activate the crusade on Cursed Mountain and complete it
Zenkala - Kill a Volcanic Wyvern on each channel
Timeless Jungle - ???

At the end of each invasion, you can get 20, 50, or 100 essences. 50 and 100 are exceedingly rare, only one person per class per invasion can get that. I've never gotten it, so plan for 20 per invasion. You can also find single essences as drops from regular enemies.

If you go for this blessing legit, it will take 200-250 Invasions to collect all. This will take you at the absolute minimum 45 days, if you manage to tag 2 fire and 2 growth invasions every single day. This is almost impossible. A better strategy is to do every invasion you can, and supplement that with buying essences on the marketplace. The prices on Teleos have been ca:

Ice, Light, Darkness 100-200 seeds
Fire, Growth 900-1200 seeds
Chaos 1600 - 2500 seeds

Overall cost between 4-5 million seeds.

Blind Executioner
This has one fragment which costs 3000 Warrior Talents. Warrior Talents drop from certain dungeons (normal dungeons with sealed chests from lvl 29 and up). Drop rate is between 10-20 per chest. You can only open one chest a day, 2 if you have valor (costs $), or more if you buy keys off the marketplace (expensive in seeds). This takes ca 200 days of doing one dungeon a day, 100 days with valor, or less if you can get extra keys.
The recent update has made this a bit faster, now Warrior Talents also drop from weekly prestige quests. This means you can get 6x(10-20) extra per week, or average 90.

EDIT: Achievement commented on BE
"Well with the update it was a lot more now. Assuming you buy keys that are 35-40k now roughly. On top of the prestige warrior talents you get now. BE might be the best choice to go with now. SC cost almost 7.5 mil star seeds. Which is about 750 dollars in the game. I have 20 alts so I generate almost 1 mil a day and that even took me awhile to get."

He's right, BE is an option. With the update, that adds only about 90 talents per week. You still need to do ca. 150-200 dungeon runs and either wait 150-200 days, or grind them out and buy all the keys. If you do 10 a day, every day, you could get this done in 2-3 weeks, but then you would need to spend 350k seeds buying keys every day, which would be around 6-7m seeds. Basically, it comes down to doing the math and choosing. Personally, if I had that kind of money I would spend it on SC essences because with BE you still have to do 150-200 dungeon runs (less if you get lucky with double chest events).

Centurion's Command
This requires you to first buy a campaign for 300k seeds, and then complete every challenge in that campaign. Suffice to say, this is currently the most difficult and time consuming thing in the game. The most difficult part is gathering all the mounts from every treasure chest. I won't list all the details, as it would be ludicrous to attempt to unlock this blessing as part of getting this achievement.

My suggestion would be to go for Nightwind and Storm Chaster. If you love dungeons and hate invasions and have no money, then Nightwind + Blind Executioner is also viable. In any case, this achievement will take you months of work.
