Deny Surveillance

For the duration, any spells or abilities that have the effect of detection (scrying, detect magic, detect undead, etc.) that are cast within or enter the area that this spell affects are instantly dispelled. If a spell such as scrying attempts to look inside the area of effect, the area is considered silenced and heavily obscured to the spell.

Recasting this spell here every day for its full duration for a year will make the effect permanent. However, it can still be dispelled.
