Grim Ring and detect the presence of undead creatures

[Waldham]

Hello, I Have a question about Grim Ring.

Quote:

While wearing the ring, you can attempt to detect the presence of undead creatures as an exploration activity. This reveals the presence or absence of undead in the area, but it doesn't pinpoint their locations.

Is it as the Search exploration activity ?

How does it function ?

Thanks for your future answer.

Due to how it's written, it will be its own exploration activity. Something like “detect the presence of undead creatures” activity.

It's weird. Looks poorly written.

Its the Detect Magic exploration activity seen Here. But for undead.

Otherwise the language is pretty much verbatim the Detect Magic cantrip.

Detect Magic wrote:

You send out a pulse that registers the presence of magic. You receive no information beyond the presence or absence of magic. You can choose to ignore magic you're fully aware of, such as the magic items and ongoing spells of you and your allies.

You detect illusion magic only if that magic's effect has a lower rank than the rank of your detect magic spell. However, items that have an illusion aura but aren't deceptive in appearance (such as an invisibility potion) typically are detected normally.

This reveals the presence or absence of undead in the area, but it doesn't pinpoint their locations. This ring can't detect undead whose appearance is masked by any illusion spell that is 2nd level or higher. If an undead is hiding or disguised, the GM rolls a secret Perception check for you against the undead's Stealth or Deception DC, as appropriate, with a +2 item bonus to your check.
