True Absorption

True Absorption is an ability only present in crystals like the Nightmare and Biocrystal. It allows for absorption of the entire energy of a consumed crystal, instead of only a fraction, making crystals in these tiers much stronger than others. By default, they start out incredibly weak compared to others, only being able to rival a few minor crystals, but they can grow much quicker. By default, any crystal without True Absorption only consume about 1/1000th of the energy of what they kill.
