I would like to see all items moved to small item slot, except really big sword, which loses its slowstrike penelty. (it's too harsh a penelty to try and break a boss with physical).
Uh... without the slow penalty the RBS would be brutally overpowered. Basically a must-have prep for any scenario where a physical resist boss is guaranteed to spawn in.
I do agree with making the other items take up a small item slot, though something will still need to be done about the shield outclassing the sword in that case.
