Soh pra saber :
<attribute key="maiclevelpoints" value="5"/>
N seria MAGIC?
Tente usar esse aki
<item id="7730" name="blue legs">
<attribute key="weight" value="1800" />
<attribute key="armor" value="10" />
<attribute key="slotType" value="legs" />
<attribute key="magiclevelpoints" value="5"/>
<attribute key="absorbPercentAll" value="5"/>
</item>
E acho que seu Movements.xml esta invertido, Movement type "Equipe" esta com um value"onDeEquipitem" e vise versa.
se eu estiver certo tenta:
<movevent type="Equip" itemid="7730" slot="legs" event="function" value="onEquipItem"/>
<movevent type="DeEquip" itemid="7730" slot="legs" level="100" event="function" value="onDeEquipItem">
<vocation id="5"/>
<vocation id="9" showInDescription="0"/>
<vocation id="6"/>
<vocation id="10" showInDescription="0"/>
</movevent>
