Few other things about Landslide itself. If you know you can't avoid it at the last minute for whatever reason, jump towards him-- it lessens the distance the knockback will push you for and potentially save you from being pushed off. You also have a high chance of parrying Landslide if you run through Titan, just before it lands and hits you (still can be pushed off from behind his back however). Also you can be pushed off during the casting time for Braver/Battledance if you're trying to snipe his heart.
