So after doing kana several times, I'm curious as to what other methods people have for dealing with the homing rocks. Here are some of the methods I have heard of or tried. What are some others?

• run away and hide behind terrain (this works but is troublesome when lava has risen quite a bit)
• use a chosen drone (i can see this working, but never tried)
• shoot it (i tried this and it did not work. maybe my dmg too low?)
• use a sonic detonator (i tried this and it did not work. maybe too close?)
• use a gravity field grenade (have not tried)
• use thunderdome (have not tried)
• use deployable shield (tried this, did not work, maybe i placed it badly?)
• use shielded crater (have not tried)

maybe the shooting method requires certain weapons? anyway post your experiences and tips for me! also make a note if the method works in normal but not in hc. thanks!
