Against All Odds

Extreme

Win a game with a difficulty rating of 17 or higher

Requires a lot of skill, a fair amount of luck, and lots of patience. I have written a guide about this specific achievement.
To setup a level 17 difficult game requires:

• A Thematic Map (+3)
  
• A Level 6 Opponent (+10)
  
• The Dahan Insurrection Scenario (+4)
  
• Branch & Claw and Jagged Earth content turned off (-2 if either is turned on)
  
• All other difficulty modifiers such as Unlimited Undo and No Blight Card disabled.

All Hands on Deck

Extreme

Win using 12 Spirits in a series of Second Wave Games

The spirits must be the 8 from the base game and the 4 from B&C and PP1. The 12 unique spirits must be played as a single series - 12 Waves of 1, 6 of 2, 4 of 3, or 3 of 4.

Bittersweet Triumph

Hard

Win a sacrifice victory (win and lose at the same time).

To satisfy this you must both win and lose on the same play. An example of this is to have one blight left on the card and use a power that wipes out the last building (Fear II) or last City (Fear III) while generating the blight that corrupts the Island completely. A more spectacular method is to play Cast Down into the Briny Deep with Threshold.

Canonical Geography

Easy

Win a game on the thematic map.

When setting up a game, click on the Balanced Map button to switch to a "Thematic Map". Choose your favorite spirit and win a game.

Choose your path

Easy

Play without Power Progression using the 4 low-complexity Spirits in the core game.

Play (win?) a game with Lightning; River; Shadows; and Vital. Make sure the "Use Power Progression" option is off on the Spirit card before you start.

Diversify

Medium/Hard

Defeat the Adversary and all Scenarios in Branch & Claw.

Purchase B&C. Then you have to

• Defeat France
  
• Win a Second Wave game
  
• Complete the scenarios - each of which have their own difficulties.
  Look for specific guides for each Scenario.

(*) Dream Firmly to Become Real

Hard / INC

Reach all 108 Elemental Thresholds available in Jagged Earth.

Requires JE DLC. Turn off B&C content when starting a game to reduce deck size. As there is a Spirit from JE yet to be released, this achievement cannot be finished at this time.

Elemental Mastery

Medium

Reach all 64 Elemental Thresholds available in the core game.

Best to turn off both JE and B&C content to finish this.

Embrace Metamorphosis

Medium

Use each of the 96 Powers available in B&C and Promo Pack 1.

Requires both B&C and PP1. Best to turn off JE content to finish this. Cast Down Into the Briny Deep costs 9 Energy to play, so if this is one of the last cards you need, best play with a Spirit that generates a lot of energy (Serpent Slumbering for example).

Empires Rejected

Extreme

Defeat all core game Adversaries on Level 6.

The core adversaries - England, Sweden, BP - are extremely challenging at level 6 and can quickly get out of control. A bit of luck and the right explore card order as well as the player being at the top of their game is required to win one of these challenges, let alone 3. There are some guides out there to point you in the right direction.

European Repulsion

Medium

Defeat all core game Adversaries.

The core adversaries - England, Sweden, BP - are beatable on level 0. Play with your favorite Spirit and you'll do fine.

Everything Old is New Again

Medium

Win at least one game with each of the 6 Aspects from Jagged Earth.

JE has 6 new aspects of the core Spirits Lightning (2), River (1), Shadows (2), and Vital (1). After creating the game, but before starting it, right click on the spirit when its in its land (it could be done before dragging the Spirit to the land) and hit the Aspect button until you get one you haven't won with yet. Win 6 games and you get the achievement.

Expanding Horizons

Medium

Use each of the 25 Innate and Unique Powers available in Horizons of Spirit Island.

Buy HoSI, Play each of the 5 new Spirits and use each of their Minor power cards (4 each) and innate ability.

Expertise

Medium / Hard

Win a game with a difficulty level of 8 or higher.

I suppose one could fiddle with the adversary and level and scenario until the right mix triggered the achievement, but why not kill two birds with one stone? It seems more efficient to get this by trying for Against All Odds.

Fear Unending

Medium

Win a game by reaching Terror Level Victory!

Choose a Spirit strong in fear generation such as Bringer of Dreams and Nightmares. Focus on minors and majors that add fear.

(*) Harness Chaos and Danger

Medium / INC

Win at least one game with each of the 10 Spirits from Jagged Earth.

There is a Spirit yet to be published so this achievement cannot be completed at this
time.

Hazardous Territory

Hard

Place 2 of each kind of Spirit Token in a single land.

Spirit Tokens are

• Badlands (JE) (adds +1 damage per token each time an action damages invaders)
  
• Beasts ( B&C) (When activated, generate 1 damage | fear per token to any invader or can move to adjacent)
  
• (*) Disease (B&C) ( Prevents build. Token is destroyed).
  
• (*) Strife (B&C) (During Ravage, a unit with at least one strife does 0 damage that turn and removes one strife token).
  
• (*) Wilds (B&C) (Prevents exploration. Token is destroyed).
  
• Presence - this achievement requires the land have 2 spirit presence (not necessarily from the same spirit).

Some notes:

• (*) Because Disease, Strife and Wilds are removed based on game action (Build / Ravage / Explore) a new one will need to be added while building up.
  
• Because Strife is one of the required tokens, the selected land must contain an Invader - preferably a city.
  
• Be on the lookout for the Minor Power Dire Metamorphosis. This adds one of each token (as well as a blight). Best to have blight cleanup powers as well.
  
• Be on the lookout for cards that add one or more tokens, as well as cards that duplicate tokens.
  
• You can also play Spirits, such as Stone or Revenge that add or prevent removal of tokens as part of their powers.

Let us not Falter

Medium / Hard

Defeat both Adversaries and all 3 Scenarios in Jagged Earth

Win a game against

• Hadsburg Monarchy (Livestock Colony)
  
• Russia

and win the Scenarios

• Despicable Theft
  
• Elemental Invocation
  
• The Great River

New Beginnings

Easy

Win at least one game with each Spirit from Horizons of Spirit Island.

Requires Horizons of Spirit Island DLC.

Here is an excellent guide on how to get this.
https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=3053577209
Some notes:

• Go to Options
  
• Enable Animations
  
• Set Animations Speed to the Slowest setting
  
• Display the Guide
  
• Exit the game, restart and follow the steps. Force quit the game after each step.
  
• Between the Quick Play and Resume Game options, you must wait until the Quick Play step has created the board and started to place the Spirit sites before force quitting so that the next time you start up you have a Resume Game option.

(*) Our Unyielding intent

Medium / INC

Use each of the 123 Powers available in Jagged Earth.

There is a Spirit yet to be implemented so this achievement cannot be completed at this time.

Over the Rainbow

Medium

Reach all 20 Innate Elemental Thresholds available in Horizons of Spirit Island.

Requires Horizons of Spirit Island DLC. Each of the 5 Spirits have 4 Elemental Thresholds.

Poisons and Perils

Medium

Place Badlands and/or Disease in every land (min 3 of each).

Requires JE and B&C. The wording is a little confusing. What this means is that of the 8 lands, every one of them must have at least one Badlands or Disease token. At least 3 lands must have a Disease, and at least 3 lands must have a Badlands. This could be 3/5, 4/4 or 5/3. Disease tokens go away after a build has been prevented, so having multiple copies on a single land (or placing them in cleared out areas) is ideal. Look for cards that add the tokens as well as Spirits that prevent Disease removal (Vengeance as a Burning Plague) or add Badlands (Stone's Unyielding Defiance) as part of their native powers / card sets.

Powers Awakened

Medium

Use each of the 102 Powers available in the core game.

Turn off B&C and JE Content to reduce the deck size.

Puissance

Medium

Win a game with a difficulty rating of 6 or higher.

A few ways of the many ways to achieve this:

• A scenario with a +3 difficulty or higher on a Thematic Map
  
• Dahan Insurrection against any level 1 adversary
  
• Any adversary at level 3
  
• Get this at the same time you achieve Against All Odds.

Red in Tooth and Claw

Easy

Win at least one game with each Spirit from Branch & Claw and Promo Pack 1.

Like the description says.

Save Your Island

Easy

Win a game.

Should be the first or second achievement earned.

Swift Response

Medium

Win a game by clearing the island of Invaders at Terror Level I.

Just be careful of not playing too many fear generating cards. Each destroyed city generates 2 fear, each town 1. You have 12 fear to play with before Terror Level II.

Alternatively, you could win the Rituals of Terror Scenario without performing any RoT.

The First Spirits Rise

Easy

Win in at least one game with each core game Spirit.

Some Spirits are more difficult to win with Solo (Ocean for instance). Might require a few 2 Spirit games - such as Ocean + River or Ocean + Lightning.

The Real Deal

Easy

Win a game with a Blight card and Adversary (other reduced difficulty options permitted).

Once you are comfortable with a Spirit, beating a Level 0 Adversary (such as BP) without the "No Blight Card" safety net shouldn't pose too much of a challenge.

The Spice of Life

Medium

Prevail in all core game Scenarios.

Once you are comfortable with a Spirit, beating the core Scenarios shouldn't pose too much of a challenge.

The Spirits Awaken

Easy

Study under Rae's guidance and complete the tutorial.

Play the tutorial.

Unanticipated Ways

Easy

Experience all of the 22 Events in Branch & Claw.

Requires B&C. Turn on B&C Content and the Events option while playing until you hit all events. It will eventually pop and then you can determine if you want to keep them in the game or never see another event. Events have positive and negative effects, so it increases the variability of the game.

Unforeseen Circumstances

Easy

Experience all of the 30 Events in Jagged Earth.

Requires JE. Turn on JE Content and the Events option while playing until you hit all events. It will eventually pop and then you can determine if you want to keep them in the game or never see another event. Events have positive and negative effects, so it increases the variability of the game. It is highly suggested that if both Unanticipated Ways and Unforeseen Circumstances are desired, that they be gone after independently, Getting any specific 1 of 22 or 1 of 30 Event to trigger is almost twice as likely in a +22/+30 card deck than a +52 card deck.

Unlock the Gates

Hard/Extreme

Reach all 52 Elemental Thresholds available in Branch & Claw and Promo Pack 1.

Turn off JE Content to reduce deck size. The real sticking point of this particular Achievement is the Elemental Threshold of the Major Power Cast Down Into the Briny Deep. First you have to find the card. Then you have to afford the 9 Energy. Then you have to have an additional 1 Sun, 1 Moon, 3 Water, and 3 Mountain. I achieved this with Serpent Slumbering. It gives a free Water, Moon and 2x Any Element as well as 12 per term at highest level. Its innate Serpent Wakes at Threshold 3 also grants an additional Major Power without the need to forget a current card in your hand.
The namesake of the achievement Unlock the Gates of Deepest Power is extremely helpful in cycling through the Major Power deck 2 at a time and giving one of every element. Look out for Gift of Nature's Connection and / or Elemental Boon as well.

Vigor

Medium

Win a game with a difficulty rating of 4 or higher.

Complete the Scenario Dahan Insurrection or any Adversary at Level 2.
