Is there a limit to how much of a sword attack speed buff you can achieve by stacking?
For example you can combine the Vog Cub Cap (Sword Attack Speed Increased: Medium) with the Vog Cub Coat (Sword Attack Speed Increased: Medium) to achieve Sword Attack Speed Increase: Very High (according to the wiki, is Very High accurate? or should this really be just High? anyways that's not my point).
What would happen if you then equipped a Swiftstrike buckler (Attack Speed Increased: High) along with the Vog Cub set (Sword Attack Speed Increase: Very High)? Would you get a crazy high sword attack speed increase or does the Vog Cub Set already increase sword attack speed as much as it can be increased?
Thanks,
Hellrazer
