Before you post something you need to dip your tongue in your brain and actually know what you're saying. Since this item exists in the game there is no actual way of abuse as you mention the item is there and everyone is free to farm it and use it as they want.So I will take your post as a suggestion which I respect and I know this item is kinda broken but it is not illegal you do not know if people are using it with macro or not you are just guessing so your post is not reporting an abuse its sharing what is in your brain. Have a nice day

There is currently almost no Observer Necklace in circulation because Silver Ore is not obtainable. In contrast, Ebony Ore can be obtained from BDW, and Brimstone can be obtained from FT. To ensure fair access, more Silver Ore or Silver Ingots need to be introduced so that all three necklaces can be obtained equally by all players.

Delos potions should have be cooldown. Actually its OK to remove that item, its not one of essential items of Knight Online. It's not good idea to let people farm this item with makro and spam this "upgraded minor healing" with makro
