Its a bit hard to explain but if you've played MMO's You'll know what Im talking about. Encourage players to continue mining after they've gotten everything they want and continue to use the same gear they had and use anvils more often to repair their old gear, as well as adding a bit more taste to RPG Server.. Simple but effective. Allow the use of materials to upgrade a weapon\armor to change its attributes through a vanilla like feel. Example: Take a diamond sword.. it has +7 Attack and say your server is difficulty 3 or has more mobs or harder mobs.. and you want to upgrade you sword or your armor. You can enchant it yes but a quicker easier way if you dont have exp is to say sacrifice 1 diamond with a 30% chance of making that +7 a +8.. and with each success the % goes down.. say if you want to get +11 then it a .5% chance. If its successful itll add a ★ in the lore.. so a +11 sword would be a ★★★★sword Possibility Unknown Question: Maybe have it work with anvils? If a weapon is at full durability and you use a diamond with it.. then itll use the % system instead of just repairing it. This I dont know is possible and if not someone please comment on this. Also what about using some type of core plugin so it affects the drops of all mobs to drop a +8 or +9 sword? to work with maybe other item plugins like Itemizer.

Did you read the "[READ ME FIRST] Plugin Requests Guide" thread? Maybe you didn't see this part : PM me your Skype so we can talk - If you wish to fill plugin requests, you do so freely. This is not a site to solicit sales for your desire to make money filling plugin requests. If there are extra details you need to fill the request, ask for them on the post itself.
If you still want this plugin, I could have a go? It's only my second so I'm not sure if I can, but I will try. There is no anvil API yet... So I will make it in the crafting table instead. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
