Wizard seen here complete in bracing sea air (5)
I believe the answer is:
ozone
This might be a double definition.
'wizard seen here complete in bracing' is the first definition.
'ozone' can be an answer for 'bracing' (I've seen this before). I'm not sure about the 'wizard seen here complete in' bit.
'sea air' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for ozone that I've seen before include "Sea air (found in layer?)" , "something found in the atmosphere" , "Kind of oxygen layer in atmosphere, has hole in it" , "Fresh, bracing sea air" , "It's said to brace" .)
