Legend of Grimrock, level 12: The prison

Legend of Grimrock, level 12: The prison

You came here from level 10, because level 11 is closed for now. Don’t worry. Level 11 is small and you will get there eventually. (All 3 last levels are small, so I’ve made the last part of this guide 3-in-1)

Another dream will appear when you unlock the door with the prison key.

Obviously, this is not Toorum, but someone else.

He tells you that the mechanism is nearby and is broken.

You need to fix it.

But first you need to fight 2 tentacle mages and explore the nearby area.

There is a place in the center of this area where 4 huge flail-wielding mechanical giants are chained and a note regarding their release will unseal the doors.

Try one.

He will charge and hit you badly when nearby.

Try to find an area where he will charge while you pump him with spells and projectiles and strafe side wise to miss his main hit.

He falls after a while giving 750 experience.

A dream will come if you sleep, telling you they drop all kinds of helpful stuff down the pits and you can get what you need there.

Pits lead to big area below in …

Level 13: The cemetery.

Legend of Grimrock, level 13: The cemetery.

Legend of Grimrock, level 13: The cemetery.

The area is filled with broken parts lying around and hornets and hydras stand in the way.

Cogs, gears, frames, nozzles, canisters, shafts, torches, …

All those in random order on the ground. There are 2 unique – A piece of ore in an alcove and another alcove with Infusor.

The cemetery main hall has 5 buttons, 2 of them are opening secret areas:

  • One with alchemy supplies.
  • One with food and firebombs.
  • Two of them open or close the portcullis with the portal taking you back to level 12.
  • One door north says “No entrance” is opened by the button in the NW corner.

No entrance.

The area behind the door has few spiders and crabs. Nothing hard.

One of the crabs will drop a gold key.

One chest with food and torches. (the wall beside him has a secret button opening a secret to the west corridor with th 6-th treasure – the Globe of Tetharion).

Alcove with 2 lizard steaks if you are short on food.

Supplies room has the blue healing stone and 3 golden locks (… you have only one key – again).

  1. South supplies are a full plate armor set.
  2. West supplies are torches, potions, mushroom caps and alchemy ingredients.
  3. East supplies are FireBlade and some bombs.

This concludes everything you may do in level 13. Come back here for healing or reviving only.

Revive The Undying one.

Now collect 1 piece of all gears and cogs and throw them inside the teleporter, so you don’t need to carry them with you. You will later find them on level 12 scattered around.

Kill the other 3 giants one-by-one if possible. This is most easily done by provoking in from 3 squares distance with projectile or spell. If you come very near – everyone will awaken and come bashing and trashing you.

They are hard by themselves and some more tentacle mages will come to spoil the hunt, so you can’t kite good. And this fight can prove hard, so don’t pull too much or you die. Every time you release one giant a mage(s) can come too, so be vigilant.

When done with the mobs and got near the center area where the giants were, the dream will come to tell you, you need replacement for 4 parts.

If you followed my advice – they will be lying around you – if not – drop from any pit to level 13 and collect. You need to place:

  • Piece of ore – North, round hole.
  • Steel gear – West, adjacent to another gear.
  • Blade gear – East, center of the other 4 gears.
  • Infusor – South, behind the frame in the center.

SAVE! Before inserting the last item. Remember very well where you placed all the cogs.

The voice in your dreams was quite bad cube-robot named Undying one, and you were just tricked to repair it to full might. Undying one cannot be killed by ordinary means.


A teleport will be open in the southeast corner of the map and the robot wills start summoning all kinds of monsters to battle you. Go away or you will be squashed 🙂 He is able to kill everyone by cornering the whole party and squishing you to a red pulp.

The teleporter will take you away in a room with a stair to level 11, but you will still hear the voice of the mechanical mind.

Go up to the tomb of Designers.

Level 11: Tomb of designers

Legend of Grimrock, level 11: The tomb

First you need to exit a poisonous corridor. 1 hidden button in the beginning and 2 hidden buttons in the end of the corridor. When you press them all, the doors will open. Hurry, so you don’t take much damage.

You will reach a fork-like area with a door in the middle needing 2 ornate keys.

  • East – 3 pressure plates with heads spewing elemental damage around them and alcove with an ornate key in the end. Use some spare junk to press the plates.

Have a look at the nearby wall for a rune-button. It opens a secret with a Goromorg Miniature (the last treasure 7/7).

  • West – Pressure plate, teleporter and 2 trap doors. Shoot a throwing knife when the teleporter is off to press the plate in the end of the corridor. This will close the first trap door. Advance over. West wall on the teleporter square has a hidden button to close the other trap door.

The area below has just one hornet for killing and you will hear the mechanical boss taunting you again. Entirely up to you if you descend or not. 175 experience is not that much.

The 2 ornate keys open a room with some fire elementals. Cool them down.

There are 2 alcoves and 4 inscriptions:

  1. Ohuj
  2. Illo
  3. Ittna
  4. Irtep

Absolutely no idea what the inscriptions mean. Probably the names of the Designers.

The alcoves have 2 scrolls claiming the designers made this whole Grimrock dungeon to hold the Undying one in and there is something that can kill him on this marble slab.

But first you need to dismantle it. When the Undying one is not whole – it can be slain.

The slab has 2 crossbow bolts 😀 How would bolts kill the Undying one!? Tingle him to death 😀 !?

If you paid attention to the 2 scrolls – One of them is speaking about shadows and it actually means complete darknes. So remove the torch from the wall, doze your own torch and/or cast Darkness. When the room is completely dark, a light will glow above the marble slab and You will receive a blaster-like weapon shooting lightnings:

Back to the Undying one.

Follow the teleporter down. Shoot the Undying one and he will be paralyzed long enough, so you remove a part of him. (You remember where you inserted them, yes?)

Every time you remove a part, he will revive and start following you again. You have 10-15 seconds, before he comes to his senses. Enough for just one removal, so you need to do this 4 times.

It takes time and precision, so be patient.

When all 4 parts are down, he is vulnerable and takes any kind of damage.

This is the final battle so hit him with anything you have.

If you get low on HP or anyone dies – use the pits to drop to level 13 and use the blue healing stone there. The undying one will not regenerate while you go heal, so you are okay.

Lightning Bombs do very good damage and the Weapon of power still hurts him quite well from distance.

While fighting, the Undying one will squash EVERYONE and sometimes the enemies he squashes will drop any of the 3 Prison keys you need to clean sweep this level, so grab them and go away quickly to any of the three prison doors to collect some stuff:

  1. North one has few healing potions to help you. (I personally found I can’t focus on the battle while healing with potions and abandoned them).
  2. East one has lightning rod (Undying one obviously hates lightnings, because he starts shouting “STOP IT!” when you hit him.)
  3. West one has some lightning bombs. Absolutely must have, if you used yours so far.

Be sure to throw everything you have at him. He has above 2000 hit points, so it takes quite a while to take him down, but it is doable.

The end and some still-frame-kinematics with the complete devastation of the whole place:


I did 😉

(Now it is time for Toorum mode ;))

  1. Ohuj, Illo Ittna and Irtep are names of authors of LoG (just backwards).

    • I suspected as much.

      A Tomb of Game Designers 🙂 (I really hope they are alive an alright, though – so they make a sequel some day).

      • In the ARPG “Sacred” was graveyards with developer’ names on tombstones. Also most of graveyard there had jokes and references to the movies and other games, there wa tombs with names of LotR characters, if i remember correctly.

        • Yeah. I remember the first game Sacred 🙂

          I wrote a text walkthrough for all dragon sites once.

          But the forum I was writing for then is long gone 🙁

          Have you tried the sequel? I never found time to play such big game again 🙂

  2. Thank you VERY much for this walkthrough! I’ve played “Dungeon Master”, “Eye of the Beholder” and “Black Crypt” in childhood, but today, after working days and family commitments, i don’t have the time for any riddle and/or hidden buttons. Right now, i’ve finished the final boss, and you helped me a LOT to come to this place. 🙂

    Thanks from germany,

  3. thanks for the walkthrough dude ! it’s great !

  4. The game is over if you don’t have a throwing weapon in 12 level “Failsafe”. My Toorum have a trouble…
    Throwing other items useless

    • No, It is not. You can kill the Cube with the Weapon of Power only. A bit slower, but he will fall.

      Method 2: Let him crush lots of the other mobs until they drop Prison key and go grab the Lightning bombs or lightning rod.

      6 bombs will kill the Undying one quite fast.

      • Not about this. Torum came into the tombs of designers without a bow, crossbow, sling, shuriken and other missile weapons. I could not get the left puzzle. bracelets, food, weapons, does not reach pressure plate 🙁
        There is no missile weapons at this level (rock for example) and no exit to other levels

        Sorry, my english is not good

        • Ah ;( Very bad.

          Have you tried reloading a previous save game and searching for projectile weapon on level 13.

          I don’t remember the whole level, but I think there are at least throwing daggers laying around on level 13.

          Or try throwing some smaller gears?

          • I had this problem as well and discovered you can throw an item as you step forward onto the pit, and it will make it across and land on the pressure plate.

  5. Thanks for this guide. It did help me a few time.
    I played it in hard mode and it took me 13 hours to finish it with 2 warriors, one rogue and one mage (all characters nearly level 14).

    • I didn’t try hard mode, but I am currently playing with Toorum.

      He is quite fun, but I miss having specialized chars.

  6. I personally used this guide :
    cause your map for level 13 was a mess. But did the rest here so thank you so much for all the effort ! 🙂

    • Good to know there are still people playing this nice game instead of Diablo III 😉

      The guide you point is very good. I did not spend too much time to draw the pictures.

      Just wanted to complete the game.

  7. Thank you for your guide. It helped me a lot in a few places. Especially information about Toorum remains. This gave me second chance to complete this game in a interesting and challenging way. Cheers to all fans of LoG and it’s ancestors.

  8. I don’t know if I’m wise or coward, but I used the door (open/close) maneuver almost everywhere!

    • It is a legit tactic to kill big mob :).

      Try playing fair with Toorum 😉 You will die alot, and there is no one around to revive you 🙂

      The start of level 4 with the 2 poison cloud mushes is just the right example.

  9. Thanks a lot for the awesome help! It’s a great game and it became free of stress for me after reading all of this.

    • За нищо. Просто писах материала докато играя.

      Изненадващо беше, че някой все още прави такива Dungeon crawlers. Минах я с удоволствие, но с Toorum стигнах само до 5-то ниво и се отказах. Изглежда трудно за соло играч 😉

      Това не пречи да му дадеш шанс 😉

      • Иронията е, че разбрах че си българин след като написах коментара 😀
        Възнамерявам да опитам Toorum, чел съм, че имало как да се развие и става много силен. Ще видя пак.
        За пръв път откривал такова упътване писано от българин. Изумен съм от перфектният ти английски!

        • Блогирам на английски защото е по-изгодно и повече хора го четат, иначе съм IT и се налага да общувам с колеги и клиенти основно на него. Ама баш пък перфектен 😉 още бъркам this and that, както и that and which 😀

          Пробвай с Toorum, ако минеш големите баталки с раците и огретата, пиши 2 реда да се амбицирам, че с това Диабло 3 само си губя времето.

          • След всичките проблеми с Diablo III и абсурдния Inferno Mode се отвратих от тази игра. Жалко, че похарчих пари за нея.

          • Абе справям се. Минавам всичко на МП4 инферно. Ама доскучава адски вече, а още не съм събрал пръстена.

          • Е те сто пъти го скопяваха това инферно. Аз едно време от самото начало играех още, когато Error 37 беше модерен и трудността беше вдигната толкова, че обезмисляше играта. Обще взето за мен тази игра беше пълен провал. Да не говоря, че Диабло е женско и има скина на Queen of Blades от Star Craft. Опитали са се да пестят – нетипично за Blizzard.

          • 🙂 Даже вицове за Чък Норис се появиха по темата. Но ще продължа да я играя, докато се изплати 😉

          • Победих играта с Тоорум и трябва да призная, че беше много забавно и относително лесно. Само в началото е сложно докато свикне човек и направи скиловете.

          • Много добър! 🙂 Бравос! Някой ден като се видя във време ще се пробвам.

  10. Thanks a lot! I only got the game when it came on Steam Sale and now I regret I only paied like 5€ for it. It was great, but I couldn’t have beat it without your guide. Thank you!

    • You are welcome 🙂 It was fun game.

      Did you play Toorum mode? It’s lot more challenging and I got to level 5 only 🙂

  11. Thx for this Guide. Helped me a lot!
