Ok, so let me describe them a bit, it was request from my customer aswell, ok so:
Party Teleporter - NPC with possibility to teleport whole party to locations.
It has check about members level, party member count, if each member is in close range from NPC etc..
Smart Enchant Manager - NPC with possibility to echant players items.
By default he has 50% to enchant your item succesfuly, ofc may be changed lol.
etc..
