<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">heroic feat</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for exploit that I've seen before include "Take full advantage of escapades?" , "Valiant deed; take advantage of" , "The deed to make gain from" , "Feat; make use of" , "Feat, accomplishment" .)
