Frequency Crystals (used by [[Turrets#Energy_Turrets|laser turrets]]), and Mining Crystals, used by [[ORE_Basic_Ship_and_Skill_Guide#Mining_crystals|modulated mining modules]] <ref group=Note name=modulated /> in EVE Online may receive "damage" and eventually be consumed (or in common terms, ''shatter''). These crystals have a Hit Point value much like any other destructible object, and shattering occurs when enough damage is taken by the crystal to lower its hit points to zero. The life expectancy of a given crystal, i.e. the average amount of time it may be used before it shatters, may be calculated from its attributes. | |||

This attribute is the chance of the crystal taking damage upon every activation cycle. For example, a Volatility of 10% would mean that each activation cycle the crystal has a 10% (1 in 10) chance of receiving damage. The actual amount of damage is fixed, and is given by the '''Volatility Damage''' attribute. | This attribute is the chance of the crystal taking damage upon every activation cycle.

The only crystals in the game whose Crystals Take Damage value is False are the Tech 1 combat crystals. These will never take damage and thus they may be used indefinitely.

With mining crystals, a cycle may begin with the activation of the mining laser and may end with either the deactivation of the laser or the acquisition of materials (ore or ice). This means that a cycle is completed even if a mining laser is turned off early. Repeatedly turning a mining laser on and off will risk damaging the crystal whether or not any actual materials were mined. | With mining crystals, a cycle may begin with the activation of the mining laser and may end with either the deactivation of the laser or the acquisition of materials (ore or ice).

One may then multiply the expected cycles by the cycle time to calculate a crystal's life expectancy over time. Remember that Volatility is a percentage, so for example, a crystal with a Volatility of 10% must use the value 0.10 in the equation. | One may then multiply the expected cycles by the cycle time to calculate a crystal's life expectancy over time.
