（1）3e的FAQ（3eFAQ自动适应3R）
No. While the discern location spell description contains some pretty strong language about the spell’s ability to overcome effects that block scrying of divinations, the general rule in the D&D game favors defense over offense, so mind blank’s ability to block scrying and all forms of divination trumps discern location’s ability to penetrate such defenses. Blocking spells of 7th level or less, however, are still ineffective against discern location.
总的来说，感知位置对心灵屏障无效。
（2）我们回到心灵屏障的原文：
The subject is protected from all devices and spells that detect, influence, or read emotions or thoughts. This spell protects against all mind-affecting spells and effects as well as information gathering by divination spells or effects. Mind blank even foils limited wish, miracle, and wish spells when they are used in such a way as to affect the subject’s mind or to gain information about it.
虽然说得很口语化，但也是强调“information gathering”的预言法术。我认为反隐应该不算是收集信息的法术。
