There's a lot of nice upgrades over sebilis but there's too many range, face and ear items! In addition someone who can do chardok can do the 3 dragons for this much better ranged item (
webtools/items.php?id=3821) or get the equivalent face item from plane of storms(
webtools/items.php?id=17214) or from sleep walker/tolapumj (
webtools/items.php?id=3397). The shoulder and back item are great but it would nice to see a few more items in those slots than all those range/face/ear items.
