Birth by Sleep The "Cheap" Strike Raid question -Spoilers-

How does this trick work on Vanitas' Lingering Spirit?

All I read is stand behind a rock and use it, saying that he can't attack you there.
I stood behind some rocks and he could still trace and attack me....

So how does this trick work? Do i need max attack haste + many Strike Raids????
Do I need a specific rock for the trick? (people claim this exists, but I haven't found a youtube video of it, except for the Ventus Tornado trick).

 

Basically, spam Slide/Dodge/Cartwheel like it's your best friend and equip Once More + Second Chance so you can survive Vanitas's cheapness of Strength, when your behind a rock while he's attacking, back away a bit from the rock and lock onto him then use Strike Raid as it'll pass the rock, thus connectign to VLS

The Tornado didn't work out for me so instead, I most spam the dodging moves and use Mine Shield or Mine Square with Terra and Ven while Aqua has a mixture with Seeker Mine, I also put in a few potions cause if you cast Cure upon yourself, VLS will annoyingly heal himself.

 

I (a little ashamed to admit it) used the strike raid trick.
Here's what you need to do. You need Once More/Second Chance. I had my attack haste MAXED OUT. Just use Quick Blitz + Sliding Dash + Fleeting Crystal to make strike raids with attack haste. I used four strike raids and had the other 4 slots filed with potions (so I could carry 20 with me into battle...though I usually only used 1 or 2 until I got VLS in my trap) If he uses that attack where he cloaks himself in a black orb and sends about seven shadow clones after you, do NOT run behind a rock. Those clones can still track you. Like Protector212 said, spam dodge roll...A LOT. The trick is when you notice VLS running towards you. Now run behind a rock. He will still try to run behind the rock to find you until you actually hit him, then his lock on you will be broken. The thing to be careful about here is that you STAY LOCKED ON! If you knock him away with the strike raid and your lock is broken, lock back on asap. If you try to use strike raid and you are not locked on to anything, then your keyblade will not go through the rock. Instead it will just stun you for a split second, and that's all the time VLS needs to go around the rock to find you. I would upload a video for you, but for many problems that I won't go into detail, I currently can not. Hope this helps. ^_^
