Hint: Easy 5-hit combo in the Torture Room:

Set up a spring board facing the crucifix (spiked wheel
on the wall). The spring board should be one square away from
the crucifix. Put the pendulum in between the springboard and
the crucifix facing the wall, so that it pushes them into the
wall. Place the saw blade on the wall pointing toward the electric
chairs. Once set up, here is how it works. Lure them to the spring
board and set it off using X. They will hit the crucifix
and become stuck for a moment. Press Triangle to launch
the pendulum. After the pendulum hits, use the sawblade to push
the crucifix down the stairs and into the electric chair. This
creates a 5-hit combo that should kill most enemies in one pass
without having to repeat the process.



Hint: Draining opponent's health:
Set a magnet wall trap then set a Blast Bomb directly
in front of the magnet wall. Stand behind your trap and wait for
your opponent to walk into it. Activate the magnet wall trap first.
When your opponent is stuck to the wall, activate the Blast Bomb.
It will drain half of their health and they will catch on fire
causing additional damage. Note: This also works with the Iron
Ball and the Flare Rock.
