Satan, possibly, ultimately cast in wax? (7)

I believe the answer is:

tempter

I'm a little stuck... Click here to teach me more about this clue!

'satan' is the definition.
(I know that satan can be written as Tempter)

I can't explain the rest of the clue.

(Other definitions for tempter that I've seen before include "Siren" , "seducer" , "Someone offering enticements" , "The Devil?" , "One offering enticements" .)

I've seen this clue in The Times.
