Conquers Rome, somehow being more charming (8)

I believe the answer is:

winsomer

'more charming' is the definition.
(winsome can mean attractive or charming)

'conquers rome somehow' is the wordplay.
'conquers' becomes 'wins'.
'somehow' is an anagram indicator.
'rome' with letters rearranged gives 'omer'.
'wins'+'omer'='WINSOMER'

'being' is the link.
