Snape's head snapped around, as Professor Sprout raised her wand, and the Potions Master managed to raise a wordless translucent ward between them. But the bolt that shot from Professor Sprout's wand was a dark brown that produced a surge of awful apprehension in Harry's mind; and the brown bolt made Severus's shield wink out before they touched, clipping the Potions Master's right arm even as he dodged. Professor Snape gave a muffled shriek and his hand spasmed, dropping his wand.

The next bolt that came from Sprout's wand was a bright red the color of a Stunning Hex, seeming to grow brighter and move faster even as it left her wand, accompanied by another surge of anxiety; and that blew the Potions Master into the door, dropping him motionless to the ground.

I interpret that as Legilimensed Sprout's magic is Voldemort's magic is Sense of Doom magic. But then how was the troll made immune to sunlight, when Harry touched the troll's skin directly?

Legilimensed? I thought Sprout was Imperiused?

Nope. Quirrell on the possibility of Lucius framing Hermione:

"From a dark alley the black-clad form of Malfoy steps forth - he would go in person, for this - and speaks to her a single word."

"Imperio."

"Legilimens, rather," said Professor Quirrell. "I do not know if the Hogwarts wards would trigger for a returning Professor under the Imperius Curse. And if I do not know, Malfoy probably does not know either. But Malfoy is a perfect Occlumens at least; he might be able to use Legilimency. And for the target...perhaps Aurora Sinistra; none would question the Astronomy Professor moving about at night."

"Or even more obviously, Professor Sprout," said Harry. "Since she's the last person anyone would suspect."

The Defense Professor hesitated minutely. "Perhaps."

I don't understand. How is Legilimens a method of mind control?

I've wondered this as well. Eliezer seems to think it is, as it's listed when one of the characters (I forget who) enumerates means of mind control including Imperius and the Confundus Charm. Possibly it's fanon?

The Potter Wiki cites Voldemort using Legilimency to send Harry visions and briefly possess him, though their connection seems like it ought to be a fairly unique case.

In HPMoR, at least, Moody was able to "reshape Harry to make him believe he was on fire", which implies Legilimency is more than just passive mind-reading.
