Valheim eitr & magic

Staffs cast with eitr, and you have none until you eat eitr food: your eitr bar is the total of the eitr in your three foods. Fish Soup gives the most, 105. Eitr regenerates at 2 per second, up to twice as fast when the bar is nearly empty, and mage gear, meads, Rested and the Queen’s power raise that.

How eitr works

From the game’s player code.

Only from foodYour maximum eitr is the eitr of the foods you have eaten. Like health and stamina from food, it shrinks as each food runs out.
RegenerationEitr comes back 1 second after you last used it, at 2 per second plus up to 2 more the emptier the bar is. Blocking slows it to 80%; attacking or dodging pauses it.
Boosts add, penalties multiplyGear and effects that raise eitr regeneration add their bonuses together; effects that lower it, such as Wet or Cold, multiply the total down.
Skills cut the costAt level 100, Elemental and Blood Magic make spells cost 33% less eitr (and health, for blood magic) and hit for 85–100% of their damage.

Questions

How do you get eitr in Valheim?

Eat food that has eitr. Without it your eitr bar is empty and staffs cannot cast. Fish Soup gives the most, 105.

How do you regenerate eitr faster?

Wear mage gear, drink Lingering Eitr Mead, rest, or use the Queen’s Forsaken power. Their bonuses add together. Avoid attacking, dodging and blocking while you wait.

What is the difference between elemental and blood magic?

They are separate skills, each with its own staffs and its own experience. Elemental magic staffs deal direct damage; most blood magic staffs list no direct damage of their own (see the table above).

Why is my eitr not regenerating?

You have no eitr food, or you are attacking or dodging. Regeneration also waits 1 second after you last spent eitr.

Eitr values, staff costs and every boost come from the game files of build 26249040; regeneration, the bonus and penalty rules and skills from the game code (Player, SE_Stats, Attack).
