Moving around while using your crux is managed using Crux Tech/CruxiFIX. This not only helps you get a faster time but may help you avoid an unnecessary death in addition.

The following methods may be applied:

• While holding down SPACE key constantly, pause and unpause with the ESC key. Your Crux tech is now active. Simply keep that SPACE key held down.

• Tapping the SPACE key for 1 frame. This is easiest to do using the side of the SPACE key. Tap for 1 frame, you will see John's crux appear. When you tap again but don't see the crux rise in John's hand? You've done it. This is typically faster than the (un)pause method.

• Hold down SPACE key, next ALT + TAB out. Stop holding SPACE key. ALT + TAB back into the game. Crux tech is now active. Alternatively, clicking out of the game window while SPACE key is first held down, releasing SPACE key, and simply clicking back onto the game window functions in the same way. Just don't hit SPACE key again once having clicked onto the game window. Crux tech is active.

NOTE: Certain enemy interactions and cutscenes remove crux tech. Simply repeat the process to activate it once again.

UPDATE: FAITH Ch. II has different damage values based depending on where your crux hits an enemy (including inanimate objects for exorcism - like the painting). Crux only deals half damage when not facing the target at hand. So, injuring any enemy from the side = half damage. Targeting an enemy head on = full damage with crux.

Secondly, you get about 1.5 seconds of free hit damage on Miriam when she does the floor pentagram. Just move after that second is up to land some extra hits during that phase of Miriam's boss fight.
