Irelia Ult Reset Bug
"If while Transcendent Blades is active Irelia is resurrected (Guardian Angel item.png Guardian Angel, Chrono Shift.png Chrono Shift) she will revive with all four blades regardless of how many she had used before dying."
This doesn't happend at least for me. I must say I play irelia for 2 years and I couldn't ever use my ult twice
