Decisive strike with daring German spirit (6)

I believe the answer is:

kobold

'german spirit' is the definition.
(kobolds are spirits in German mythology)

'decisive strike with daring' is the wordplay.
'decisive strike' becomes 'KO' (knock out blow).
'with' means one lot of letters go next to another.
'daring' becomes 'bold' (I've seen this before).
'ko'+'bold'='KOBOLD'

(Another definition for kobold that I've seen is " Germanic goblin".)

I've seen this clue in The Guardian.
