Applying overlapping skills to reduce difficulty in Numenera


I know in Numenera you can apply maximum of 2 difficulty reduction from a skill check. Is there any guidance on applying overlapping skills? Some examples:

  • Character tries to identify plant people. They’re trained at plants and animals (two separate skills), thus reducing difficulty by 2.
  • They try to to dash and jump. They’re trained in athletics and jumping (again, separate skills), -2 difficulty.
