If you get a message that "You feel slight tingling in your hands," that means Loricatus tried to harden your weapon but was unable to. Failure can occur for a number of reasons:  * Loricatus can only harden his aligned materials; tin into copper into bronze into iron into steel into meteoric steel into adamant. * There is a failure chance. The probability of a successful hardening depends on your relationship with Loricatus; even at maximum relationship there is only a 5% chance of hardening meteoric steel into adamantine. Any non-aligned materials such as leather, glass, or octiron will ''always'' receive a tingling message. In this case If your weapon cannot be hardened further, you may want to temporarily "wield" your gauntlets or some other item that needs hardening, since Loricatus can harden any type of item, as long as it is held in your hands and made of the correct materials.
