Strong Ghosts

Strong Ghosts are a type of ghost first seen briefly in the Old Clockworks and then in every subsequent mission. They are normal ghosts that have been augmented (strengthened) by a special red Crystal excavated by the ghost-controlled mining complex known as Secret Mine, greatly increasing their toughness and damage. They vary in strength from the Strong Greenie which is only a moderately strong enemy, to the Strong Poltergeist which is powerful enough to be considered a sub-boss.

Strong Ghosts can be strengthened even further by wrapping Paranormal Chains around them. This grants them tremendously increased health and damage as well granting them ability to barricade doors with additional Paranormal Chains.

Appearance
Strong Ghosts are identical to their normal counterparts in terms of shape and size but have their normal coloration reduced down to little more than appropriately colored stripes on their bodies, granting them a somewhat cracked, multi-layered appearance.

Health per variant
The formula for calculating the health of a Strong Ghosts is the following:

Health of the subject ghost multiplied by either 2, 3, 4, 5, 8.3 or 10 (multiplier varies from ghost to ghost)

NOTE: Ghosts with infinite HP (Creepers and Possessor Ghosts) cannot be strengthened.
