In multisell *.xml file don't forget to change item id, don't make same id (red letter).
Production (item show on ur npc list), ingredient (cost item).
ex.:
Code:
<?xml version='1.0' encoding='utf-8'?>
<list maintainEnchantment="true">
<!-- Blood Mark -->
<item id="1">
<ingredient id="57" count="10000000"/>
<production id="1419" count="1"/>
</item>
<!-- Alliance Manifesto -->
<item id="2">
<ingredient id="57" count="20000000"/>
<ingredient id="6392" count="20"/>
<production id="3874" count="1"/>
</item>
<!-- Seal of Aspiration -->
<item id="3">
<production id="3870" count="1"/>
<ingredient id="57" count="40000000"/>
</item>
<!-- Blood Oath -->
<item id="4">
<ingredient id="57" count="10000000"/>
<production id="9910" count="1"/>
</item>
<item id="5">
<ingredient id="57" count="20000000"/>
<production id="9911" count="1"/>
</item>
<!-- Caradine's Letter -->
<item id="6">
<ingredient id="57" count="1000000000"/>
<production id="7679" count="1"/>
</item>
</list>
