Duration 1 hour
You make the object
invisible. This makes it
undetected to all creatures, though the creatures can attempt to find the target, making it
hidden to them instead if they succeed. If the item is used as part of a hostile action, the spell ends after that hostile action is completed. Making a weapon invisible typically doesn't give any advantage to the attack, except that an invisible
thrown weapon or piece of ammunition can be used for an attack without necessarily giving information about the attacker's hiding place unless the weapon returns to the attacker.
Heightened (3rd) The duration is until the next time you make your daily preparations.
Heightened (7th) The duration is unlimited.
