These steel kiteshields are special items that are painted with a special crest you can choose from the Herald in the White Knights castle in Falador. To paint a steel kiteshield you need level 43 crafting.
They have the same stats as a regular steel kiteshield, but they are untradeable. Once you have painted the shield, you cannot remove the crest. You may only have one crest at a time.
Certain crests have requirements to allow you to get them and please note these god shields are not from treasure trails, god trimmed items are totally separate.
