# TFT attack speed bugs and Guinsoo's Rageblade

I tried placing a Guinsoo's Rageblade on Yasuo, considering his muti-hit ability. Watching his attack speed stat I observed that the ability did indeed stack attack speed. However, at the end of each ability his attack speed reset to his base attack speed. I've seen other mention of this with Olaf and Yasuo on the PBE forums (below). https://boards.pbe.leagueoflegends.com/en/c/bugs/Hg8fu3Tg-tft-bug-attack-speed-items-are-not-working
