Mending

0-level (Cantrip) Transmutation

This spell repairs a single break or tear in an object you touch, such as a broken chain link, two halves of a broken key, a torn cloak, or a leaking wineskin. As long as the break or tear is no larger than 1 foot in any dimension, you mend it, leaving no trace of the former damage. This spell can physically repair a magic item or construct, but the spell can’t restore magic to such an object.

Light

0-level (Cantrip) Evocation

You touch one object that is no larger than 10 feet in any dimension. Until the spell ends, the object sheds bright light in a 20-foot radius and dim light for an additional 20 feet. The light can be coloured as you like. Completely covering the object with something opaque blocks the light. The spell ends if you cast it again or dismiss it as an action.
If you target an object held or worn by a hostile creature, that creature must succeed on a Dexterity saving throw to avoid the spell.

Minor Illusion

0-level (Cantrip) Illusion

You create a sound or an image of an object within range that lasts for the duration. The illusion also ends if you dismiss it as an action or cast this spell again.
If you create a sound, its volume can range from a whisper to a scream. It can be your voice, someone else's voice, a lion's roar, a beating of drums, or any other sound you choose. The sound continues unabated throughout the duration, or you can make discrete sounds at different times before the spell ends.
If you create an image of an object—such as a chair, muddy footprints, or a small chest—it must be no larger than a 5-foot cube. The image can't create sound, light, smell, or any other sensory effect. Physical interaction with the image reveals it to be an illusion, because things can pass through it.
If a creature uses its action to examine the sound or image, the creature can determine that it is an illusion with a successful Intelligence (Investigation) check against your spell save DC. If a creature discerns the illusion for what it is, the illusion becomes faint to the creature.

Prestidigitation

0-level (Cantrip) Transmutation

This spell is a minor magical trick that novice spellcasters use for practice. You create one of the following magical effects within range:

• You create an instantaneous, harmless sensory effect, such as a shower of sparks, a puff of wind, faint musical notes, or an odd odor.
• You instantaneously light or snuff out a candle, a torch, or a small campfire.
• You instantaneously clean or soil an object no larger than 1 cubic foot.
• You chill, warm, or flavor up to 1 cubic foot of nonliving material for 1 hour.
• You make a color, a small mark, or a symbol appear on an object or a surface for 1 hour.
• You create a nonmagical trinket or an illusory image that can fit in your hand and that lasts until the end of your next turn.
