Instead of an overall permission node, there should be something like..
<BypassPermission>blacklist.bypass</BypassPermission>
<BlacklistItems>
<Item ItemId=“1441” Name=“Shadowstalker Mk. II” CanCraft=“false” CanSpawn=“false” CanTake=“false” CanStore=“false” />
</BlacklistItems>
<BypassPermission>blacklist.lock</BypassPermission>
<BlacklistItems>
<Item ItemId=“1441” Name=“Shadowstalker Mk. II” CanCraft=“false” CanSpawn=“false” CanTake=“false” CanStore=“false” />
</BlacklistItems>
Just so some players can have access to specific items, but not have overall access to all blacklisted items.
