Foresight and Odor Sleuth
Near the end of the data structure, there are three bytes that signal the end of the normal part of the table - FE FE 00. There are only two entries after this, and they are Fighting and Normal on Ghost, respectively.
However, this area of the table is unique in that all entries in it are ignored after Foresight or Odor Sleuth is used, simply reverting to normal damage.
The end of the table is marked with FF FF 00.
