Cloaked in illusion, the target becomes
invisible. This makes it
undetected to all creatures, though the creatures can attempt to find the target, making it
hidden to them instead. If the target uses a hostile action, the spell ends after that hostile action is completed.
Heightened (4th) The spell lasts 1 minute, but it doesn't end if the target uses a hostile action.
