Does try different level (7)
I believe the answer is:
destroy
'level' is the definition.
(I know that level is a more specific form of the action destroy)
'does try different' is the wordplay.
'different' indicates anagramming the letters (letters placed in a different order).
'does'+'try'='doestry'
'doestry' is an anagram of 'DESTROY'.
(Other definitions for destroy that I've seen before include "Completely ruin" , "Ruin; pull down" , "Demolish; pull down" , "put to death" , "Annihilate" .)
