Asgard
Completed Asgard.


Vanaheim
Completed Vanaheim.


Svartalfheim
Completed Svartalfheim.


Helheim
Completed Helheim.


Defeated Nidhogg
Defeat Nidhogg on any difficult with any Valkyrie.


Walking through the portals on Asgard II, Vanaheim II, Svartalfheim II, and Helheim II, will get you each respective achievement. Walking through the portal on Helheim I will get you the Helheim achievement. Once credits roll you'll unlock the Nidhogg achievement.

Göll Ascending
Defeated Nidhogg with Göll on easy.


Göll - Of War
Complete the game on hard as Göll.


Göll is your basic starting character. Use your time playing her to learn items, enemy attack patterns, etc. Her secondary ability is a fireball that deals damage over time to whoever it hits. It can be really useful against shield enemies, or enemies with weak points on their back.

Freyr Ascending
Defeated Nidhogg with Freyr on easy.


Freyr - Ruler of Peace
Complete the game on hard as Freyr.


Freyr is the second character you will unlock. He starts with a great magnum, but 150 shield health. The easiest way to get around this is to get a shield converter, which will instantly convert all shield health into permanent health. It's possible to get this on the first floor in Huggin's shop for 7 coins. His secondary ability is block, which can help you maintain your early shield health.

Hildr Ascending
Defeated Nidhogg with Hildr on easy.


Hildr - Of Battle
Complete the game on hard as Hildr.


Hildr is the third character. She starts with 50 regular health, 25 shield, 5 speed, a key, and the four clip shotgun pistol. I prioritized getting more health with her as soon as possible, but I don't feel like there's a key strategy you need to win with her. Her secondary ability is the same fireball as Göll.

Njord Ascending
Defeated Nidhogg with Njord on easy.


Njord - Ruler of the Sea
Complete the game on hard as Njord.


Njord is the fourth character, who starts with 50 health and his unique magic weapon. You can't change his weapon at any point, so I prioritized getting my stats up as quickly as possible with him. Items that synergize well with Njord would be Quarternote (double shots), Face of Death (double damage), and Giant Slayer's Boots (% damage) for bosses.

Njord's secondary ability is Valkyrie's Veil, which gives you a free hit after killing a few enemies. This can massively help with your survivability!

Odr Ascending
Defeated Nidhogg with Odr on easy.


Odr - The Frenzy
Complete the game on hard as Odr.


Odr is the final character you will unlock. He starts with unlimited flight, but dies in one hit and has the double barrel shotgun for his starting weapon. I would argue that the double barrel is the worst starting weapon, especially on Odr, as its base range is tiny. I would recommend prioritizing getting a new weapon for this reason. The longer the range, the better, as you'll be able to hit enemies from higher up.

Odr massively benefits from getting the Valkyrie's Veil ability for survivability, or the Lion Heart item for one free hit. Otherwise, your main form of defense is using your flight as effectively as possible. If you prioritize killing enemies with ranged attacks early you can trivialize a lot of rooms and bosses by constantly staying in the air. Make sure you're using your flight to ensure that you search every room for high up secrets. If you're lucky, this will be a great way to rack up early stats.

Offensive items that can be useful for Odr include (thanks for the recommendations Rostan):

• Snap Fingers (Celestial Drumroll) - Damages all enemies on the screen and can melt bosses
  
• Celestial Wave (Damage All Enemies) - Secondary ability that hits all enemies in the room - can clear small enemies easily
  
• Rhythmic Chaos Boots (Strike to the Beat) - Attacks random enemy each beat, so you can focus on dodging

My final tip for Odr is to only play him on hard. Odr will always be a difficult character, with or without his teleport secondary ability.

Skuld Ascending
Defeated Nidhogg with Skuld on easy.


Skuld - The Debtor
Complete the game on hard as Skuld.


Skuld starts with 150hp, but loses HP constantly. However, you get HP back whenever you shoot an enemy. HP gained increases with how many projectiles hit the enemy, making shotguns and the Quarternote items useful.

Skuld starts with a very powerful weapon (Garand), making quick room clears easy early in the run. The key to a successful run with Skuld is speed. Speed ups, sprinting, and minimal backtracking are all good things to keep in mind. The vamp health headpiece (Circlet of the Serpentine) also helps keep your health topped off, although your built in effect is stronger in my opinion is a nerf to your health regen, avoid it picking it up on Skuld. Thanks Han and xenira for the input!

Cursed Iron (DMG up, convert all HP to shields) could be very useful. Once all her HP is converted to shields, she stops losing health (since you only have shields). You no longer have health to vamp and only way to heal is pick up shields and HP ups, but at least you're not dying over time anymore. Thanks Death Wish for the tip!

Geri Ascecnding
Defeated Nidhogg with Geri on easy.


Geri - Odin's Hound
Complete the game on hard as Geri.


Geri starts with the pistol, 25hp, and a much lower camera than the other characters. Geri comes with the big bonus of having a guaranteed bank on each floor (until Helheim). This makes it very easy to buy out any first floor shops if you see any max HP ups or better weapons.

Herfjötur Ascending
Defeated Nidhogg with Herfjötur on easy.


Herfjötur - The Fetter
Complete the game on hard as Herfjötur.


Herfjötur starts with the bolt-action rifle and three coins. Herfjötur uses his coins as HP, and whenever you take damage you lose half of your coins (rounded down if odd). It's possible to kill yourself by spending too much, so make sure to keep track of your coins in shops. Damocles' sword coin bags add to your total health, and then you lose half. This means that it's only worth grabbing them at lower coin totals.

Make sure to use the bolt-action rifle's high base range to avoid damage as much as possible. Consider spending coins anytime you're in the double digits to avoid losing large chunks of money at once. If you can get the ultimate that creates coins or pull coins from the bank you have close to unlimited health!

Rún Ascending
Defeated Nidhogg with Rún on easy.


Rún - TheMystery
Complete the game on hard as Rún.


Rún starts the game with a random weapon, item, and health total. You can even start with high-tier weapons that aren't available in the armory. If you don't like what you start with you're able to instantly restart and get different loadouts. The amount of benefits he starts with makes him one of the easier characters to win with.

SanngriðrAscending
Defeated Nidhogg with Sanngriðr. Well done!


Sanngriðr - The Cruel
Complete the game on hard as Sanngriðr. Impressive.


GrasluTheFirst
Completed Sanngriðr on Hellish.


Sanngriðr is your reward for beating the game with Odr, and she is a much harder character. She starts with the pistol, no flight, is a one-hit kill, has no permanent starting spells you can unlock, and must clear every enemy filled room (other than challenge rooms) to unlock the boss door for the floor. On top of all this, she is also the only character to have an achievement for finishing the Hellish difficulty.

The same items that are helpful on Odr will benefit Sanngriðr. Additionally, if you can get one of the permanent flight items, you'll have a much higher chance of surviving. Good luck!

Mastery
Completed the game on hard with every Valkyrie.

See each character's section for individual tips.

Multiplier
Get a score of over 700,000.

This achievement will pop the second you get a score of 700,000. There are two main factors to consider when going for a high score:

• Multiplier - Consecutive attacks to the beat will increase your multiplier (up to x4). Any attack, reload, or ability off the beat will reset your multiplier to x1. Getting hit will also reset your multiplier. You need to keep this multiplier maxed out as much as possible.
  
• Time - You'll notice that you lose points with each beat. As your run continues the points will increase, to hundreds per second. For this reason you want to backtrack as little as possible.

Here are a few things I found useful when going for high scores:

• Using infinite ammo weapons will help you maintain your streak, as you won't have to think about switching weapons
  
• Having the Valkyrie's Veil ability will prevent your streak from being reset if you get hit once in a while.

Due to these two tips, I'd recommend going for high scores on Njord once you've beaten the game on easy with him.

Keep in mind that if you use a character other than Njord you should try to avoid using the gatling gun, as it won't raise your score like other weapons.
