Rapturous oriental tactics reformed (8)
I believe the answer is:
ecstatic
'rapturous' is the definition.
(synonyms)
'oriental tactics reformed' is the wordplay.
'oriental' becomes 'e'.
'reformed' indicates anagramming the letters.
'tactics' anagrammed gives 'cstatic'.
'e'+'cstatic'='ECSTATIC'
(Other definitions for ecstatic that I've seen before include "In religious fervour" , "On cloud nine" , "Feeling great rapture or delight" , "Overjoyed, quite delighted" , "Cites act to be delighted" .)
