Decompose causes the user to faint. The Pokémon that takes its place has its Defense and Special Defense boosted by one stage, and heals 1/16 of its maximum HP at the end of each turn until switched out. This healing is increased by 30% if the recipient is holding a Big Root.
The move will fail if its Trainer has no other conscious Pokémon in their party or if used by a wild Pokémon. Heal Block cannot prevent this move from being used, but if Heal Block is used on the recipient Pokémon the healing effect will be accordingly disabled for the duration.
