That obstacle that's been in your way for months, maybe years? It's not going anywhere on its own. This is three days of concentrated force built to obliterate it — not soften it, end it.
 
If you've tried everything else, this is the one you haven't tried. Booking is limited — the block isn't waiting, and neither should you.
 
Best for: long-standing obstacles, extreme cases, blocks that laughed off lighter work.
