Find a weapon that has bound whatever that weapon is (for example, a katana with bound 
long sword) and cast the Bound spell. When the weapon appears, hold X + R and your 
weapons will continuously switch. When the bound weapon wears off, your stat with the 
weapon should have increased dramatically. For example, it is possible to raise my 
longs word skill from 50 to over 2000 in about five minutes.
