This achievement is unmissable. It is obtained normally simply by playing through the game regularly.

For this achievement, you don't have to get the entire song perfect. You simply need to successfully execute each spell that you cast. In the statistics window, your Spells Attempted/Spells Cast should be 100%.

The easiest way to get this early without prematurely ending the battle is to keep casting barrier and healing spells to drain your mana slowly. As you drain it, just keep on repleneshing your mana via the mana field.

The Mana Recovered stat is in the same box as the Accuracy stat.

After the tutorial, you will have the option of fighting enemies over and over. This enables you to farm an enemy multiple times until you get all of its drops.

The Holiday Whompa is located on the first floor. You can fight it immediately after the tutorial is done. It has a slightly higher BPM than the other 2 enemies but it is just as easy to defeat.

The only thing that you sacrifice when you synthesize an item is experience. Crafting materials get sent back to you if the process fails. Experience on the other hand is an unlimited resource so you can imagine that this achievement is actually straightforward.

You can earn this achievement as soon as synthesizing becomes available to you. You will need to synth a scroll that can teach you magic if you complete the condition plus pay the price (experience). Just score 100% on one of these opportunities to get the achievement.

For the sake of simplicty, I did this achievement on Casual while fighting a Violent Dwarf from the 2nd floor. Get the enemy's hp low enough so they die after 1 more Arclight. After setting it up, wait until just a little under 8 seconds (7.8~7.9) to activate Arclight. If done right, the spell will finish casting under the 1 second mark. If you look at the video closely, you'll see that I activated Arclight over 8 seconds. You can still do this but I you will barely make the cut. In that video I ended up beating the enemy at 0.97 seconds left on the clock.

You can do this achievement as soon as you reach Floor the Fourth and get Spell Slot 5. I recommend using the highest mana items currently available to you as well as a Goblet which reduces mana costs by a percentage. I also advise equipping your lowest cost spells. In my case it was Azure Wind, Trigger Boost 1, Fallout, Spheric, Arclight. You can also use Barrier instead of any other spell in there.



Once you have the items and spells assembled, start a battle with any enemy and wait for all your cooldowns to come off. Immediately switch to the Mana Field right away. Once all of your spells are ready, cast them all in quick succession (LB or RB). I recommend using the spell with the logenst sequence first (to give you time to activate the other spells). The achievement should pop up as soon as you cast them all.

There are only 2 poison spells (Damage Over Time) in the game. One is Fallout and One is Miasma. Simply kill one of the floor one mobs with this one spell to get the achievement.

Since Spheric is your lowest cooldown spell, it is your best choice in obtaining this achievement. At around level 12-13 with the best offensive items currently available to you, you will be able to kill the lowest HP Floor the First monster in one shot. Cast Spheric as soon as it is off cooldown and you should get the achievement.

Story-related. This one is obtained after beating Floor the Fifth.

For this achievement I strongly recommend bringing a cooldown accessory (Candlestick). I also suggest fighting the Sunlit Storm because you are given over 4 minutes to keep casting Arclight. That should be enough time to kill it for the achievement.

To get this achievement you simply need to cast Trigger 1 and 2 (to boost each other) successfully in the same battle.

Story-related. Gained for defeating the final boss after Floor the Seventh.

Iridium is crafted by synthesizing a Half Prism, Prism Half, and a Radiance. The Prism halves can be obtained by crafting recipes from the regular floors. Radiance is gained from the boss after the 7th floor.

Here are all the recipes gained in each floor/level.

*** The final boss room and ??? have not applicable labels because instead of having recipes, the boss fights there drop completed products. ***

The scrolls for Luminary Storm and Amber Glow are obtained from the final boss after floor 7.

The only thing I have to say about this achievement is that you should at least practice the Luminary scroll before attempting it. It's as hard as you would expect for one of the final tasks in the game. Even more so if you are musically challenged. The biggest obstacle when doing Luminary Storm's song is that it changes pace a few times going from super slow to super fast. It also costs 15k experience per attempt which is why I urge you to practice first no matter how good you think you are.

The item 'Extract' which is dropped by Sunlit Storm has a description in binary. When it is translated to ASCII, you get /tcag. Solving this puzzle leads you to http://www.playiridium.com/tcag

Well done, Ky.

While on the "Gear" screen, hold down the Left Trigger, Right Trigger, A, Y, and then press Down on the D-Pad. (Alternately, hold down 'C', 'A', and 'N', and then hit the comma key.)
You're the key. The genetic fulcrum. If only you knew what Mir was attempting to do.
But perhaps, this way, it is best.

After crafting Iridium, you are able to access ??? from the floor selection menu. Inside you will find a copy of your consciousness. Once you beat him, you will get an item called tnlug.exe. This item will enable you to see the hidden ending after beating Mir.
