Clawice is currently giving +6 sound attack instead of the +3 that's stated in the item description.

As far as I can tell this isn't the case. What method did you use to test this?

[Trexmaster]

This is still a problem in 2.71b.

This applies to -ALL- materials in the game. Not just Clawice.

You can test it by reading your applicable elemental ATK value (let's use sound to go with this bug report) after equipping the appropriate material weapon.

Check without a Clawice weapon, then equip a Clawice weapon.

You should notice you're going up +6 instead of +3.

You can try with literally any other material that grants ELE ATK, they all do this.

EDIT: This may be related to a bug I found where materials on non-weapons are giving the +3 ELE ATK you'd expect from being on a weapon.
