Weapon of Sheer Force

You infuse a mundane weapon with the might of a giant. At the end of the 1 hour ritual, you touch a nonmagical weapon. Until the spell ends, that weapon becomes a magic weapon with a +1 bonus to attack rolls and damage rolls, and the wielder of the weapon uses its Strength modifier for attacks and damage rolls instead of its previous attack and damage rolls. 

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the bonus increases to +2. When you use a spell slot of 7th level or higher, the bonus increases to +3.
