'arthurian knight' is the definition.
(knight in Arthurian legends)

'weapon back to lake' is the wordplay.
'weapon' becomes 'lance' (lance is a kind of weapon).
'back' says the letters should be written backwards.
'lake' becomes 'l' (geographical abbreviation).
'to'+'l'='tol'
'tol' in reverse letter order is 'lot'.
'lance'+'lot'='LANCELOT'

'takes his' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
