Emden's Decapitator is a literal killer technique. Cestvs' muddy consciousness recalls the single knockout blow his master Zafar taught him. Furthermore, Emden has been injured by Cestvs' attacks so far. He could win by trading blows... But in the next moment, Emden's fist cuts Cestvs' brow, which begins bleeding into his eye. It's kill or be killed. While one of Cestvs' eyes is blinded, Emden attempts to finish him off.
Suddenly being blinded in one eye 
will ruin his visual judgment.
فقدان النظر في عين فجأةً
سيخلّ بحكمه البصريّ
Mit nur einem Auge kann er
Entfernungen nicht mehr einschätzen.
Esto arruinará su discernimiento visual.
Esto echará a perder su análisis visual.
Impossible de jauger les distances
en étant borgne !
Non potendo più vedere da un occhio
non riuscirà più a giudicare bene le distanze.
Ficar cego de um olho vai acabar
com a noção de distância dele.
С одним глазом
он будет хуже оценивать бой.
