	/// The CockEater Ability bites off the first found non-artifical cock of an target pawn. 
	/// It will restore {MINIMUM_LIFEFORCE_GAIN} multiplied by up to 2-times the Cock-Size. 
	/// Consuming a "towering" cock will give 2*{MINIMUM_LIFEFORCE_GAIN}, resulting in default 0.5f LifeForce. 
	/// This number is reduced for consuming animals by Settings.
	/// 
	/// Balancing note: With the Cock-Eaters a drain of 0.08 is normal per day. This means 1 average cock should hold for 3-4 days of fertilin-fuel and half a day for an animal.
