Amulet of Towering Rage

I am back to playing Dungeons and Dragons again. A friend is running a campaign set in an alternate Europe in the year 1530. As part of that campaign, I created a new magic item, the Amulet of Towering Rage.

Some color text on how the Magnus created the item in the 1530s European campaign:

   The smith looked at Magnus after he finished the mold and said, “You said that you would provide the metal needed.” Magnus nodded, and looking at Wulfgar asked, “Do you have it?” The stocky Viking replied, “Da, taken from an orc I killed ven I vas under the Frenzy of Odin.” Wulfgar then pulled out a falchion and handed it to the smith.

   Taking out a hammer and chisel, the smith expertly clipped off the final 3” of the blade. He then dropped the fragment in a ceramic crucible and placed the crucible in the hearth. Working the bellows, the smith began to melt the metal.

   After a few minutes, the smith said, “It is nearly ready for casting. Be you ready for what you need to do.” Magnus spoke to Wulfgar in a low voice, “Wulfgar. Think of how you feel when within the Frenzy. Feel the rage and power it gives you.” Wulfgar nodded and in a moment his pupils narrowed to pinpricks and the vein on his forehead seemed to throb.

   Magnus told the smith, “We are ready.” The smith took a pair of tongs and pulled the crucible from the hearth. Smoothly, Magnus pulled out a needle and taking Wulfgar’s left hand, pricked Wulfgar’s little finger. Holding the finger over the crucible of molten metal, he squeezed out three drops of blood. There was a hissing as the droplets hit the liquid.

   Magnus then dropped a pinch of powdered ruby and the hair of a king bull into the crucible. He then focused his mind on the incantation of the Enlarge Person spell. Instead of targeting one of the people in the room, though, Magnus quietly cast the spell on the metal in the crucible, thinking of the blood of Wulfgar.

   When the second of the spellcasting was done, Magnus shook his and in a rough voice told the smith, “Pour.” The smith poured the metal from the crucible into the mold awaiting it and commented that it would take a while to cool. Magnus replied in a weary tone, “That is acceptable. The casting took; I felt it. Well done.”
