- Ishida's dad made an Silver Arrow from the silver he recovered from his wife's body (victims who have their powers stolen by Yhwach eventually dies from a silver clot in their heart), the silver arrow can negate his powers.
- The arrow was fired by Ishida Uryu, who had has " The Antithesis" powers, which was stated to be able to counter Yhwach's " Almighty", so he didn't see the Silver Arrow coming.
- Aizen was there and his hypnosis still works on Yhwach, so he was able to fool his senses and buy time for everyone.
- Tsukishima used his past-altering powers on Ichigo in order to fix his Bankai. As result, Yhwach could no longer instantly break Ichigo's blade nor instantly alter his future. (He could still, however, damage the blade through sheer power).
- The arrow loses it's effects after one second and Yhwach start recovering his power, however...
- Yhwach's subordinate, Hashwalth, holds "The Almighty" when Yhwach is asleep. He received a vision of Ichigo killing Yhwach, and, instead of just pass to him, he altered to make it seem like it was just a dream, instead of a vision from the future. As result, Yhwach did not see the final blow.
- In the vision, Ichigo killed him with his fake Shikai, which never made any logical sense. So when he tried to destroy Ichigo's Bankai, he was only able to destroy the outer shell. The Bankai's inner shell, that has the form of the fake Shikai, sliced through him. Because Hashwalth withheld this vision from him, Yhwach never saw it coming. Since he had not fully recovered, the blow was became fatal.
