Get a head start on Roots Of Yggdrasil with these tips and tricks.

Valkyrie is unique in that it requires you to complete a specific mission during a game. To reward the extra difficulty of unlocking her, she's perhaps the most powerful scion the game has to offer, so here's what you need to do to find Eir and how to get the most out of her unique abilities.

How to recruit Eir, the Forsaken Valkyrie

The cursed valkyrie Eir, awakens from her slumber in the Roots of Yggdrasil.

Eir's recruitment process isn't complex once you know what to do, but it can be challenging and requires a bit of early luck.

After reaching Asgard a few times, you'll notice an event constantly appearing on the second set of sub-islands; a cave containing a caged figure which you cannot explore before the darkness chases you even further. Here you can find Eir, but only if you can get the key to her prison.

The key itself appears as an artifact you can collect, but unlike the others found in the game, it appears in one place. Norns have a chance giving you the Cursed Key at the beginning of each loop. It is the only artifact with an exclusively negative effect, adding the burden keyword to a card in your hand each turn (reduction of cards drawn while holding the card).

The norns offer a curious gift at the start of a loop in Roots of Yggdrasil.

Your quest is to carry this key to the end of a loop. Once you reach that mysterious cave in Asgard, you can use the key to unlock Eir, and she'll join you permanently. This event doesn't appear randomly once you've unlocked it, so you don't have to worry about carrying the key all the way there for anything.

Recruiting Eir will also provide the ability to
build a market at Holt
allowing you to trade surplus resources such as spare acorns.

The cursed key makes the game more difficult and you don't want the run to end early before you can use it. There are a few different methods you can use to maximize your chances of finding the key and making it through.

Advice	Details
Early loop	You can end a loop early from the pause menu. This allows you to reroll Norna's gifts repeatedly until they give you the key.
Trials of the Gods	Setting the trials of the gods to a lower level normal level will prevent you from being overwhelmed. Not only do you carry the key, but you also drop a more useful gift from the Norn.
Take Kare	Kare's passives and scion power help complete this quest. Its power generation allows you to explore the islands quickly and its pulling power offsets the burden imposed by the key.
Rebuild your Holt	Changing Holt buildings can make the challenge easier. Avoid scavenger stations that run low on suppliesor merchant guilds that add hold to your cards. Both will penalize you for having burden keywords in your deck. prioritizes buildings that give you extra starting cards, such as Statues of Heroes. Watchtowers and Barracks can give you extra income to start with and maybe, ensuring you can explore quickly even with fewer cards.
Focus on clearing islands quickly	On a normal loop, it can be a good idea to stay late on an island to collect extra artifacts and acorns for later. When you carry the key, free time is more valuable than an extra acorn and Eir's market can make up for any lost saplings in the long run.

How to use Eir, the Forsaken Valkyrie

Cursed Valkyrie Eir caused great fires and rainstorms due to her curse from the Roots of Yggdrasil.

Once unlocked, Eir offers a rather unique playstyle that is contrary to the other descendants. A quick look at her powers and she'll seem weaker than the rest of the cast.

Cursed Valkyrie seems to be a purely negative card for her descendant power. It spawns a threat on the map and has the hold and charge keywords, reducing your drawn cards if you refuse to use them.
Her first passive, The war cryprovides three incomes when a threat occurs. This includes those generated by her descendant power, giving it a positive application.
Her second passive, Valkyrie's Protection gives one population point for every 40 people spent. This can be spent on exploration, flowering saplings, or combating threats.

Compared to Liv and Thrasir's starting abilities, Eir seems worse for resource generation, but produces harder to obtain Might resources instead of supplies. The big difference between War Cry and other descendant passives is that War Cry's revenue lingers on the islands.

The general playstyle for Eir is to spam Cursed Valkyrie as often as possible to gain massive amounts of power from War Cry. This allows snowball to explore later, allows him to build a more economic card focused deck without the need for power generation.

Cursed Valkyrie can produce manageable threats like draugr towers, but it could be more
urgent danger, such as setting fire to your ship
.

You don't need to have a strike card in hand before using the power, but it's normally a good idea to have a power card that you can use to clear roots or fires if needed.

The best books for Eir

Rotos fighter guide of Yggdrasil, who provides Eir with massive amounts of supplies.

Eir benefits from cards that directly respond or exploit threats on the maps. Raiding camps can be a good way to generate income against non-urgent threats like storms, while barbarian camps can be used to instantly eliminate urgent threats or to save hit cards for later use.

The Fighter's Guild, which provides 50 supplies for every threat you've cleared this island with, can support Eir's economy on its own, but requires the placement of nearby buildings.

Eir has little use for cards that only produce income mightsuch as barracks or springs. You'll often want to focus on other aspects of your economy, but you should still keep a few watchtowers and others around to set up synergies, complete objectives, and put out fires.

The best type of housing for Eir

The two best houses for Eir are Heroic Houses and Nomadic Houses.

Heroic houses generate population when action cards are used. Since Eir likes to use his downforce for cooldowns and will often stay on the islands until night, you'll have plenty of Curse action cards that generate population and gives you new card drafts to use both now and to prepare for the next island.

Nomadic homes use their existing income. Nomadic houses generate population from explorationallowing him to quickly build up a decent population using the power generated by the War Cry.
