However, here are some possibilities depending on what you have in mind:
* A mythical or fictional weapon: If you are thinking of a weapon used by a devil in folklore or fantasy, it could have many names. You might consider names like:
* Devil's Lance
* Infernal Spear
* Blackthorn
* Shadow's Edge
* A real weapon with a devilish reputation: Some real weapons might have been given names with a "devil" association due to their ferocity or the reputation of their users. For example:
* Devil's Anvil (a large hammer used in war)
* Black Prince's Spear (a historical weapon known for its effectiveness)
To help me give you a more accurate answer, could you tell me:
* Where did you hear the term "devil's spear"? Was it in a book, movie, game, or somewhere else?
* What kind of context are you thinking of? Is it a mythical creature, a historical figure, or something else?
Knowing this information will help me understand what you're looking for and provide a more specific answer.
