Maybe if stat falls below required talent/weapon/armor, state "Your weapon suddenly becomes too heavy to wield!" (drop in inventory)
-or for daggers "You suddenly feel too clumsy to confidently wield the *** dagger!"
-or for staves "You suddenly struggle too much to harness the intrinsic energies of the *** staff!"
-or for talents "You have forgotten that talent."
Not sure with the talents such as Health and those things--I know I've been abusing stat boost items to get it
