Gameplay Notes

See Invis spells no longer spot the sensor for scrying. Warlock crawling eye can still be seen with see invis as it's a physical object.

Basically this is outclassed by Blindsight if you can learn both as a Sorcerer/Wizard. The differences are:

• See Invisibility:
  • Spell School: Divination
  • Levels: Bard 3, Sorcerer/Wizard 2.
• Blind Sight:
  • Spell School: Transmutation
  • Levels: Cleric 3, Druid 3, Sorcerer/Wizard 2.

This is purely a counter to Invisibility, and does not work on Etherealness at all. If cast, all invisible creatures appear as if they were not invisible.

SRD differences
