ive noticed underwater action items have a higher level req.
ive also noticed moderate and heavy fort items do not drop as much. ive seen one moderate item drop and im at level 10 and have done a fair chunk of quests including some repeated runs of dead shall rise and desert caravan for loot. this could be my imagination but on khyber i feel like i had found a fair number of moderate fort items before giant hold.
with all the f2p players running durks..lotsa muckbanes hitting the ah i might actually be able to own one of these now.
previoulsy hard to find scrolls are more common and drop in pairs. firewall, d door,solid fog, symbol of flame etc seem to drop a fair amount.
anything else ? nicked weapons make the sword of pain obsolete.
