Experience/ED


 * Entity data
 * : The number of ticks the XP orb has been "untouched". After 6000 ticks (5 minutes) the orb is destroyed. If set to -32768, the age does not increase, thus the XP orb does not automatically despawn.
 * : The health of XP orbs. XP orbs take damage from fire, lava, falling anvils, and explosions. The orb is destroyed when its health reaches 0. However, this value is stored as a byte in saved data, and read as a short but clipped to the range of a byte. As a result, its range is 0-255, always positive, and values exceeding 255 overflow.
 * : The amount of experience the orb gives when picked up.
