ToME: the Tales of Maj'Eyal

Preternatural Senses cannot see through Stealth or Invisibility, unlike anything else that can detect monsters outside of LoS.

What beside Hymn of Detection, Arcane Eye, and Keen Senses can detect invisibility? These talents say then can detect invisibility, too. Track is another talent like Preternatural Senses that can let you detect NPCs outside your LoS, but you still can't see invisible or stealthed NPCs.

lukep, help me remember how Preternatural Senses works with invisible enemies outside your LoS on an otherwise unseen, unlit tile. Does the tile show up as seen, but without an actor on it?

It shows up as seen, with a slightly different colour than lit tiles while outside of your LoS/Light radius.
