<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">increases</span>' is the definition.<br/ ><span class="explanation-format__explanation">(augmenting is a kind of increasing)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for augments that I've seen before include "Extends" , "Stun game makes larger" , "Adds to, increases" , "Enlarges or increases" .)
