@DashXavier 110 % is the max you can get in attack speed on Ultima and it can only be achieved with Centurion/battle; if this answers your questions.
Also, I don't think you understand how things work : the only way to raise your attack speed on pso is through battle units or special armors (such as the Odoshi kind). There is also some combinaison (like Gratia & Yasminkovs) that allow you to get more speed. You also got some very rare example like Sacred Duster which is a weapon that set your attack speed to 30%.
Attack speed is not cumulative, only the best bonus will be applied.
So this cap of 40% you're talking about can only be achieved by Blue Odoshi Violet Nimaidu (a hunter armor), Heavenly/Battle and v101 as far as I know. Then it jumps to 110% with centurion/battle.
