Focus

Use
Hold down the FOCUS/CAST button to drain Soul and regenerate health at a rate of 1 mask per 33% Soul.

Continuing to hold the FOCUS/CAST button will continue to heal 1 mask of health as long as the player has 33% or more Soul. This also skips the startup time.

If the player does not have enough Soul, they will not be able to use Focus. However, if a player uses Focus while at full health, or does not perform a full cast of Focus, they will still use up stored Soul.

How to Acquire
The player starts the game with this ability. A tutorial prompt will appear the first time the player is injured, but the player may still activate Focus before this.

Modifiers
Several charms change the way Focus works:
 * Baldur Shell gives a small protection while focusing.
 * Deep Focus allows the player to heal 2 masks of health at half the speed.
 * Hiveblood heals 1 mask of health over time without focusing.
 * Joni's Blessing prevents the player from being able to heal.
 * Quick Focus allows the player to Focus at twice the speed.
 * Shape of Unn allows the player to move slowly while focusing.
 * Spore Shroom creates a cloud of damaging spores after 1 "burst" of focus.
