You can use an action to blow this horn. In response, warrior spirits from the Valhalla appear within 60 feet of you. They use the statistics of a berserker. They return to Valhalla after 1 hour or when they drop to 0 hit points. Once you use the horn, it can't be used again until 7 days have passed.
Four types of horn of Valhalla are known to exist, each made of a different metal. The horn's type determines how many berserkers answer its summons, as well as the requirement for its use. The DM chooses the horn's type or determines it randomly.
|01-40||Silver||2d4 + 2||None|
|41-75||Brass||3d4 + 3||Proficiency with all simple weapons|
|76-90||Bronze||4d4 + 4||Proficiency with all medium armor|
|91-00||Iron||5d4 + 5||Proficiency with all martial weapons|
If you blow the horn without meeting its requirement, the summoned berserkers attack you. If you meet the requirement, they are friendly to you and your companions and follow your commands.
