Description

You create visible bell of force that latches itself to the target's neck. If the target doesn't possess a neck, it attaches to some other body part in a way that doesn't prevent the target's movement. When choosing a target, the caster may choose to have the spell target the nearest invisible creature within range. That way, they can attempt to cast the spell on a creature that they are unable to pinpoint. The bell rings with the slightest movement, making stealth impossible. The target takes a -20 to stealth checks if it's moving. In addition, the bell is always visible, effectively negating invisibility. The bell can only be removed early with a remove curse, break enchantment, or similar removal spell.

When augmented

If cast as a level 2 spell, it lasts for 1 hour per level. If cast as a level 3 spell, it lasts for 1 day per level. If cast as a level 4 spell, it's duration is permanent.
