During the previous battle,
I was poisoned and unable to move.
تمّ تسميمي في المعركة السّابقة
.وكنتُ عاجزًا عن الحركة
In meinem letzten Kampf wurde ich vergiftet
und konnte mich daraufhin nicht mehr bewegen.
Durante esa batalla, me envenenaron
y ya no fui capaz de moverme.
Durante la batalla,
Durant le précédent combat,
du poison m’a paralysé.
Durante l'ultima battaglia,
Durante a batalha anterior, eu estava 
envenenado e incapaz de me mover.
В ходе поединка с демоном
меня отравили и обездвижили.
