This section is incomplete. Please feel free to edit this section to add missing information and complete it. Reason: In which games does the Life Orb boost the damage dealt by Future Sight/Doom Desire (other than Generation VI)? Does it deal damage to the user for these moves, and when?.
Boosts the power of the holder's damaging moves by ~30% (5324/4096), but the holder takes damage equal to 10% of its maximum HP after it uses a damaging move (rounded down, but not less than 1). It does not boost the damage for self-inflicted confusion damage or moves that deal direct damage, but the holder still takes damage when using direct damage moves.
If a Pokémon steals a Life Orb with Thief or Covet, it will take damage for the use of that move that stole the Life Orb. The Life Orb activates before Pickpocket, so even if a Pokémon's held Life Orb is stolen by Pickpocket, it still damages the attacking Pokémon for that move. If a Pokémon steals a Life Orb with Magician, it will take damage for the use of that move that stole the Life Orb. If the holder uses Fling, then Life Orb boosts the power but doesn't damage the user.
