In my story, there is a sword similar to J. K. Rowling's Sword of Godric Griffindor. When you are in danger, it will appear next to you, and then you can summon it later on. It will also replicate and save the powers of those who summon it (e.g, fire user summons it, now can light itself on fire.) It has 3 abilities when it enters the hands of the MC: summoning lightning, shrinking to a knife, and unlocking doors, all 3 of which I plan to use. My main character finds it in the start of the book while fighting monsters. How can I stop him from becoming overpowered?
Because I cant accept multiple answers I'll just put bits and pieces here,
Like the Ring of Power in LOTR, this sword is sentient, and handicapped only by the fact that it requires another to wield it. Like the Ring of Power, as the sword is used, its hold on the wielder grows and the interests of the wielder gradually become the interests of the sword. An unwary wielder will tumble headlong into this trap and immediately fall victim to the lure of overpoweredness, and just as quickly lose his own agency. Instead of wielding the sword, the sword wields him.
Say your sword is one of a whole class of magical weapons, and that certain amulets/charms can either protect against their effects or nullify their abilities completely.
Anyone linked to the sword is eventually sucked dry and then their powers stop working. That's why there are only three powers left when our hero finds it in that bandoned tomb. Over the centuries there have been many users but all but three are dead. The last three agreed to seal the sword in the first place, realising the curse.
Here are the problems with the sword:
- The curse makes people reluctant to link to the sword.
- Even then each power only has so many uses before the power-owner dies.
Thank you all!
