Blue robe not working

[ruda]

Using TFS 0.2.13

<item id="2656" article="a" name="blue robe">
		<attribute key="description" value="It is a magic robe."/>
		<attribute key="weight" value="2200"/>
		<attribute key="armor" value="11"/>
		<attribute key="slotType" value="body"/>
		<attribute key="magicPointsPercent" value="10"/>
	</item>

But nothing happens, no damage increased. How do I fix it?
