I don't recall what it was like on Switch, it didn't challenge me at all.

I remember on Wii U, either her level 2 or 3 was really tough. Took place in the mines/tunnels area and there's an utterly insane amount of captains that end up swarming your base, I think it's one of those "defeat the leaders of 2 armies" things. Then I realized as long as I stuck near the main base, it was actually a godsend to have so many enemies bunched up in my HQ as long as I kept on the move.

Gate is disjointed from Lana, once the summon pops out, you can immediately dodge cancel and move away while it does its thing. You gotta take advantage of that and the outright invincibility (any time there's a blue orb around her) she has from like the last half of her normal string and all of her summons except C1 and C2.
If you're constantly popping summons, repositioning, repeat.... it's one of the safest weapons in the game, should be nearly impossible to lose due to damage taken. It is NOT a weapon to run straight into the fray and stand there and button mash.
