Do we have this?
A weapon simply can't be wielded by someone who doesn't meet the requirements, even though they can normally wield weapons of its type, generally an Ancestral Weapon
usable only by someone with the right Heroic Lineage
. This is traditional of any Sword In The Stone
- Dungeons & Dragons has the potential for an item to have restrictions on the name, sex, race, or alignment (only the last two are present on any significant number of pre-published items). It also provides a work around in the "Use Magic Device" skill, which let's a user "bluff" an item into using it.
- Fire Emblem!
- "Prf" rank weapons can be used only by their assigned wielder. Typically this is a "Rapier", a slightly better than normal sword with large bonuses against armored and cavalry units for the game's main character and given no explanation for why no one else can use it (The dancers in the third game could, but otherwise exclusive). The variants wielded by Lyn (a magic sword that "chose" her) Hector (his "favorite axe") and Ike (custom made for him) receive some explanation, but most don't. The most Egregious is Micaiah's Thani, which is just stolen from a random chest.
- Legendary Weapons in the entire series generally stick with the Heroic Lineage variant. The 4th game makes breeding the lineage a gameplay mechanic.
- Averted in Castlevania Portrait of Ruin, the Vampire Killer can be used just fine without the ritual to bind it to Johnathan, it just becomes a mundane whip with damage that only beats bare hands (It has a good deal more range, but that's it).
- The Trope Codifier is the Sword In The Stone which only the rightful king of Britain can draw.
