What grants it
Nothing you can carry grants this one. It comes from the world — weather, water, fire, a fall — rather than from an item.
Valheim shows you a short line of flavour text for Eikthyr and nothing else — not the size of the change, not the duration, and never what applies it. The 3 modifiers above are read from the game files, and the 0 sources beside them turn the effect into something you can plan for rather than notice.

Eikthyr in Valheim
What does Eikthyr do in Valheim?
It applies the 3 changes listed above. The in-game tooltip describes the effect in words and gives no numbers, so those come from the game files.
How do you get Eikthyr in Valheim?
You do not get it on purpose. Nothing you can carry applies Eikthyr; it comes from the world — weather, water, fire or a fall — which is why there is nothing to craft for it.
How long does Eikthyr last?
5 min. Reapplying it restarts the timer rather than stacking a second copy, so there is no benefit to drinking two.
Can you use Eikthyr again straight away?
No — it has a cooldown, listed above with its duration. A Forsaken power is the clearest case: it runs for its full length and then you wait, which makes when you trigger it matter more than which one you carry.
Does Eikthyr stack in Valheim?
Not with itself. Applying Eikthyr again replaces the existing one rather than adding to it, so a second source is spent for nothing unless the first has run out. It does sit alongside other effects perfectly happily — the restriction is on duplicates, not on how many different effects you carry.
What else is like Eikthyr?
Other effects in its category number 14, among them Adrenaline Rush, Adrenaline Rush, Adrenaline Rush, Adrenaline Rush, Anti-Sting Concoction. They are worth comparing before committing to one, because effects in the same category tend to be alternatives rather than additions — and one of them is usually easier to keep running than the rest.
