Fall and Rise


Banish the Darkness


For Gondor


Peace in Death


Stalemale is Victory


Banished


Brought to Heel

Fit for War

Ability that every non-white gear have. Do it once and boom! Achieve done.

The Stuff of Legend

Only 2 sets are guarantee to get. One is set of necromancy, after some time in main questline - next one is set of bright lord, that you can obtain by doing all "shadows of the past" challenges in every region. Rest are grindy grindy. To do this achieve, just equip 6 parts of the set that has same bonus.

Rule of Three

Unlock three slots for gems. Each unlock cost 1000 Mirians(that silver pay-to-win coins)

Forger

Master Forger

Craft better gems combining 3 of lower tier ones. Do it until you'll get master gem. You need 3^4 lowest tier gems to craft master one. Which means you need 81 common gems to craft it, minus all higher quality ones which you will combine together, to shorten the process.

Vandal

Monuments has nothing to do with crafting, but each destroyed will drop a guarantee gem.
With proper skill unlocked, you can get higher tier gems from statues. They can boost your gem crafting considerably, so search for them.

Vertical Mobility

Let some maggot without proper weapon kill you. No name n00b on lvl 1 with wooden hatchet...yes he has to kill you!

Nemesis

More dying to this noob (you don't really have to die, but encounter him on the map and escape - NO KILLING!). Three times to be precise. He's not a no name anymore, and has some armor by now...and even better toothpick to fight some naughty tarks!

Everything is Permitted

He propably has higher level than you can recruit, so shame him(sometimes more than once) to derange this guy.

If You Can't Beat Them

Recruit guy from vertical mobility achievement. (could be other orc, but if we can do few achievements in one chain - why not?)

Bad Boss

Smack that naughty orc - he deserved that. Left clicks until he starts to bleed. Let him die. Then ress him on Army screen.
If he betrays you before dying - then dominate and order him, to stay and fight with you. Start smacking again. LMB until he dies - then ress him through army screen.

Death is not the End

Smack some orcz and ressurect them.

Avenged

Let some orc kill you to create vendetta mission. Then kill him via vendetta mission.

Promise Keeper

Now grab some intel[ark.intel.com] and blackmail that guy before going to vendetta mission. Tell him something mean like..."Yo momma so old she knew Gandalf before he had a beard! Me and you tommorow near city walls -fistfight- or whole school will know this!" He'll be mad now - less focused on future fight against you.

Life of the Party

Send one of your destroyer orcs to kill your nemezis - it will be normal rivalry mission.

Power Couple

Then support your destroyer with another one - any class will do.

Speak Friend and Enter


Haedirs->Ithildin parts->Elf ghost boi challenges->RIDDLE!->profit

Second Age Warrior

Complete all Shadow of the Past missions in one region. Some of them will require to buy and equip specific skills.

Finished Tales

"Hello Haedir my old friend..." Search for Gondor artifacts through haedirs, and then collect them.

The Web Revealed

Same as Gondor artifacts, but with Shelobs memories.

Let our foes fortify with Iron and stone
Let them sumon scabrous Serpents, feral beasts
It will Avail them nought. Across the Ages none
Have an army that wield such weapons, such Woe
Such doom against the dark-benighted Hordes who dare
Claim dominion over a Mordor soon bright.

Fair Mordor Slumbers, entangled in night
A vipers' Nest of sorrow and strife
Poisoned by pernicious betrayal and blight
Trapped in the grasp of gelid corpse-hands.
Yet behold! The Bright Lord Comes as a wildfire
Burning only what is Base, that all else may thrive.

They stalk and Lurk, then lash out so furious
Yt our Bulward is proof against their rage.
Our hard-ringed, hand-forged armor Impervious
To predations from the Powers of darkness
No matter how Vicious or how vile.
To assail the Bright Lord is to falter and Fail.

When the sun Rises, the shadows must retreat
Fleeing in fear frmo the Fires of dawn.
The Night never knew that its end was fleet
As a Bright Lord bears Beacons of flame.
The rises, yes -- but from the West it Shines
Marching e'er Eastward, e'er eternal, e'er bright.

In the land of Mordor where the Shadows lie
We bear our banners aloft, boots like Drums
Our Cadence quick, our countenance dire
For who is in this dark, dream-haunted Land dares
Resist the righteous flame of Wrath
And Doom themselves to despair and death?

Follower Perks

ESC/ARMY/MY ORC/ORDERS/TRAIN/TOP ROW/RIGHT SIDE/ADD A HORDE

Feed the Beasts

Click Hit bait and wait for pray. You need to clickbait all of them at least once:
-Caragors
-Graug
-Drak
-Spiders
-Ghouls

Rough Rider

-Normal Caragor (common doge)

-White Caragor (uncommon doge)

-Drak (rare guy, but can be baited)

-Frost Graug (East side of Seregost; caverns)

-Fire Graug (Middle-West of Gorgoroth; smal canyon)

-Poison Graug (West Coast of Nurnen; cliffs and caverns)

All graugs found naturally can be elemental ones (region determines element). Caged graugs will be normal ones 100% of the times. Also you can distinguish elemental graugs by their horns and different bodies (green/red/white). Frost graug also have fur.

Carnan rideable animal forms does not count to this achieve.

Wild Things

Draks from time to time will land to chill warm our green fellows. You can smash him with graug fists when he's near ground. All graugs can throw a rock at long range. Elemental graugs can split fire/snow/acid - this short range attacks can no-scope hit drakes flying at low attlitudes. Also you have a bow...use it as well.

-Assassin
-Beastmaster
-Berserker
-Commander
-Destroyer
-Marksman
-Tank
-Tracker
-Trickster
-Slayer

First you need to find this missions through Haedirs.
Some of them will be locked. You have to buy and equip proper skill/s to play them.

Trolling

Some consider this achieve to be pain in the ologs ass. It's not that hard, but you need proper preparations. At least one olog in near area, and one capt'n with slither of health, preferably one-touch-and-death capt'n. Stun olog with "E" when proper quicktime even will pop-up. Mount that naughty boy and smack greenskin out of his life essence. BOOM! Now you have a plan - go and realise it!

Blood on Blood

One orc treated another one with mug-o-grog, now they are friends aka bloodbrothers. Dominate one of them and order him to kill his bloodbrother. After killing or sometimes even before doing it - he will betray you, so watch out! Bloodbrother has to be killed by his bruddah to get this(kill steal will be enough).

Best Defense

Each upgrade cost mirians. Only one can be equipped per commander, so don't buy 3 of them per orc, becuse it will be mirians lost. Check what you need and buy it.

Hostile Takeover

Not sure what to do here. Never done that...

I Like to Watch

Rivalry mission - send one of your orc that has a bit more level than your opponent, or someone that can use your opponents fears. Don't interfere, just watch how your boi is killing that orc scum. Unless your "black horse" will be beaten...then repeat process, as your boi need to kill opponent.

Bound by Blood

Someone is dead. Revenge him. You need internet connection for that. Online vendettas has their own icons - they are easy to find. Only one active per map.

Dismantled

Kill a guy who commands an oupost...nothing fancy.

Forged by War

34 base skills to unlock. Skill upgrades does not count. Not all abilities are shown since begging of game. Wait for plot to accelerate.

The Operative

Bodyguards needs to be set by game. This won't count if chief don't have at least 2 bodyguards before your interfering. You have to dominate them and send to infiltrate. When all bodyguards will be your spies, then new mission will appear on map - betreyal[i.imgur.com]! Do what you must...

Such Great Heights

Do some online conquests. Try to achieve gold as much as you can. A bit of grind and you'll get this.

No Orc Left Behind

It's separate type of mission, you'll get notification when your follower will be captured for 1st time. Most of the times happens when you lose a fort.

Better Luck Next Time

Kinda RNG based. Enemies killed by throwing of the edge has higher chance to rise without your help. Another by the way achievement.

Purge

STOP! HAEDIR TIME!

Overkill

Both followers has to be your dawgs. Order one to fight another in pit. One of them will die, so pick da worst ones. Let the olympics begins!

It Came From Within

Every chief inside fortress has to be your spy except head chief. When siege begins, you'll get this one.

No Orc Lives Forever


A bit grindy, but it explains itself. There are 3 pit missions per region. You can check your progress in quest tab.
There is guide on Steam that explains it by Chief & Kuraiken. It is for online pits, but offline ones are similiar, except you can outlevel your opponent.

Flash Mob

Most of your skills will blind later, so don't bother grinding it - you'll get it by the way.

Gauntlet

external guide with pictures[www.trueachievements.com] for artifacts locations

Bombardier

Easy - you don't need to kill them in one glide, you can do it in 8 replays if you want.
Watchout for concussion bolts, as this legendary upgrade bugs steel bolts, and make this achieve unobtainable in current playthrough. You have to repeat steel bolt kills next replay if you did not get them before upgrading crossbow.
