In his new cursed armor, Guts does not feel pain. This makes him near unstoppable, to the point that even one of the apostles of light cannot defeat him.  But even if he doesn't feel pain, the damage still remains, and the armor itself threatens to engulf his soul...
Without pain, humans become 
incredibly strong and agile.
بدون الألم، تصبح قوة وسرعة البشر سريعتان للغاية
Menschen, die keine
Schmerzen spüren,
Privato di esso, un essere umano
Sem dor, humanos tornam-se 
 incrivelmente fortes e ágeis.
