The item information is wrong : - for the container version, it says "Placing this augment into a one-handed blunt weapon will change the look of the weapon into that of the augment." ; - for the type 20 version, it says "Placing this augment into a bow will change the look of the bow into that of the augment.". Same goes for Shield of Air Ornamentation (two-handed piercing weapon / bow), Shield of Earth Ornamentation (one-handed piercing weapon / shield), Shield of Ice Ornamentation (one-handed blunt weapon / one-handed piercing weapon) and Shield of Fire ornamentation (one-handed slashing weapon / one-handed slashing weapon).
Same goes for the H2H Ball of Sunlight Ornamentation : "Placing this augment into a one-handed slashing weapon will change the look of the weapon into that of the augment."
