Directional Shard Lock

Requirements

 * Hatchet Heel (Technique), Flashing Air Kick (Technique) or Valkyrie Sword (down, down + attack)
 * If you have Hatchet Heel or Flashing Air Kick learned, then equip any Shoe weapon (nothing equipped in the Weapon slot is the same as having a Shoe type weapon equipped)
 * Otherwise, equip Lethal Boots (it has Hatchet Heel innately available) or Kung Fu Shoes (it has Flashing Air Kick innately available)
 * Any Directional Shard equipped
 * Example: Heretical Grinder
 * Make sure you have enough MP for both the technique and the cost of using the Directional Shard.

How to perform

 * 1) Jump.
 * 2) Hold the Directional Shard button.
 * 3) While still holding the Directional Shard button input Hatchet Heel (down, down + attack). Must be very low to the ground if using Flashing Air Kick to do the glitch.
 * 4) You should now be locked into the Directional Shard stance.

Properties
While in Directional Shard Lock the Directional Shard used will stay active even if no MP is available. Your actions are limited to backdashes, crouching, sliding, weapon techniques and manipulation shards. Everything else will either fail or break the state.

You will lose this state if you:


 * Take damage.
 * Enter another room.
 * Jump.
 * Attack.

Known soft-locking cases:


 * Entering another room which has a door transition.
 * Using the warp while in this state.

Shard Swapping
Swapping shards while the glitch is active can lead to unusual effects. The effects vary wildly depending on which shard is "locked" and which shard is swapped to. A few examples are listed here, but this is not a comprehensive list of possible effects:
 * Heretical Grinder locked, swapping to another channeling shard results in the channel no longer consuming MP
 * Heretical Grinder locked, swapping to a non-channeling shard results in the effect's origin anchoring in place on the screen (though it can still be rotated) and no longer consuming MP. It can be unanchored by swapping to another channeling shard.
 * Void Ray locked, swapping to a non-channeling shard results in the effect's origin and direction being anchored
 * Directed Shield locked, swapping to another channeling shard results in the channel no longer consuming MP
 * Inferno Breath swapping to a non-channeling shard results in just the dragon head effect being anchored, the actual flames continue to be emitted from Miriam's location as normal.

Applications

 * Preemptive damage on certain boss fights.


 * Conserve MP items
 * To save the most MP simply use this glitch at the minimum amount required.
