I believe the answer is:

lucre

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

'fortune' is the definition.
(thesaurus)

'raised after he's left hercules' is the wordplay.
'LUCRE' is hidden back-to-front within the letters.
However, I am not sure how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for lucre that I've seen before include "Scornful word for money that may be 1 Across" , "Money or wealth" , "(Filthy) profit" , "Profit dishonestly obtained" , "Possession of the rich" .)

I've seen this clue in The Irish Times.
