Dream Nail

WIP

Function
''Hold [DREAM NAIL button] to charge and slash with the nail. Cut through the veil between dreams and waking.''

Allows the player to extract Essence from memories and dreams. Also restores 33% of the player's SOUL if used on living Enemies.

How to Acquire
The Dream Nail is acquired in the Resting Grounds by inspecting the Dreamer Statues. Doing it so will send the player into a dream where they will receive the Dream Nail from a Moth.

Essence
Essence is the energy gained from multiple sources after obtaining the Dream Nail. After obtaining certain amounts of Essence, the player can return to the Seer for rewards.

Essence Sources: Essence rewards from the Seer:
 * Using Dream Nail on a Ghost
 * Collecting floating Essence spawned by a Whispering Root
 * Defeating a Dream Warrior
 * Defeating a Dream Boss
 * 100 Essence - Hallownest Seal
 * 200 Essence - Spirit's Glade opens
 * 300 Essence - Pale Ore
 * 500 Essence - Dream Wielder
 * 700 Essence - Vessel Fragment
 * 1000 Essence - Arcane Egg
 * 1300 Essence - Mask Shard
 * 1500 Essence - None?
 * 1800 Essence - Awoken Dream Nail

Ghosts and Dreamers
Dreamers are the remains of a deceased bug given visible form. They are only visible in-game after acquiring the Dream Nail. There are three types:
 * Passive: These ghosts will not attack or harm the player in any way, and the player can engage in conversation with them or ignore them. Using the Dream Nail will absorb them, granting 1 Essence.
 * Dream Warriors: These powerful ghosts have enough energy left to challenge the player in combat, if the player desires. Defeating one absorbs the ghost and earns you a set amount of Essence.
 * Dream Bosses: After defeating a Dream Boss, the ghost of the boss will appear over their corpse and acknowledge the player before being absorbed, granting a set amount of Essence.

Trivia

 * It is not necessary to use the Dream Nail on passive ghosts to fully awaken the Dream Nail (and unlock other story endings).
 * It is unknown whether or not ghosts are the bug's spirit, a lingering spectre, an imprinted memory, or some other form of thing other than they are made of Essence.
