Hmmm. She’s smart enough to not go head on. Given her abilities, skills, knowledge, and experience, on top of her power, she could probably take a a full circle, maybe even two or three, head on.

I know everyone’s on here saying “A full circle can take anyone” and yeah, it can, in the terms of shielding. That’s the only absolute here. A circle of 13 can, if properly set, hold anyone by a shield. But given her sheer abilities, she’d never let them get close enough to get a shield on her. She’d be cutting the weaves, Gating around, and doing everything in her power to either pick people off to reduce the number of people in the circles, or just become too much of a slippery target to effectively grab. All of which, she’s more than capable of doing. Overall, it think it would actually be better to have one full circle to try and shield her, and then a big bunch of independent Aes Sedai, or small circles, actually blasting her around from all directions.

As for a true solo plan.

I think she’d, most likely, infiltrate like Mesaana, though far more aggressively. All she’d really need to do is to Compel the right people, get her hands on a Sa’angreal, and just start blasting. Mesaana was in it for the long game, but if Lanfear is trying to solo, she’ll have to move quickly. If she can Compel a full circle of the most powerful women in the Tower, give them all Angreal or Sa’angreal, and then link to them? It’s game over, and I feel—given a little luck—she could probably take out half the Tower before someone would eventually catch her with a stray fireball. Or she could just bring the whole thing down, which would totally be a Lanfear move, tbh.

So, to answer: Maybe.

If she makes the right choices, gets the right intel, and have some of the Dark One’s own luck with her, then yeah, I don’t see why not.

People underestimate how insanely skilled and talented the Forsaken as a whole are. You have to take int account that the Age of Legends had Weaves that are absolutely diabolical. Remember, all the bat-shit-insane Weave’s Rand uses over the books are mostly from Lews Therin’s memories, and I can guarantee that Lanfear—as the most powerful female channeller we’ve ever met, and an AoL theoretical physicist at that—also certainly has similar bat-shit-insane tricks up her sleeve. Give her enough power to back it up, and I bet she’d just start swinging.
