Charge Weapon

During this ritual you touch a nonmagical weapon and imbue it with magic. That weapon becomes a charged weapon. It is treated as a magic weapon with a +1 bonus to attack and damage rolls. The effect remains for 10 minutes or the magic effect is otherwise dispelled.

The spell is treated as a third level ritual but it is possible to expand higher spell slots to imbue it with stronger magic. This option however is only available to certain classes.

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.
