They are working on a MythicDrops system, which is similar to "Diablo Drops, with random enchants and stuff" but as I've seen they may have found another idea. Honestly I suggest this Mythic Drops or Artificer's Enchants + this one blacskmith mod I've seen is amazing!
The way I've seen how this other mod works is: You first enchant an item, (Perfectly good wit heroes) then use a blacksmith's anvil to upgrade it (Right clicking a regular anvil lets u try to repair, instead of /skill repair, but lighting a fire 2 blocks under, so the anvil doesnt smother the fire, will let you upgrade on that anvil instead)
Rightclicking the anvil with fire starts to upgrade:
Power for Bows
Sharpness for any tools (or efficiency, I'm sure it's editable)
Protection for armor
Meaning in order to get the best enchants on a sword, you must first enchant your sword, then hand it over to a blacksmith to upgrade. Once this is done, you can go to an articifer's table (This is useable by any prof, but could maybe be for master enchanters)
All profs should get a skill called "Siphoning Gem" which triggers when you kill somebody. When they are killed they give a soulgem of similar value to their level, (EG: Level 1 Warrior = Petty Soul Gem, Level 65 Dragoon: Legendary Soul Gem)
To use an artificer's table, one must put an enderchest right under an enchantment table, rightclicking this
opens a certain type of GUI, where you put a soul gem and a tool and it will fill a "Slot" on the tool (All tools have 2 slots, but certain slot enchants either give an extra or don't take one up"
These slot enchants give bonuses too, such as "Savage - +4 Damage" or "Hell - Do 50% bonus damage in the nether, +2 Damage" etc.
All in all, I prefer the 2nd system, and yes, I'VE PLAYED WITH THIS ON A VANILLA SERVER so it's comepletely do-able. In the coming days I'll ask the server admin on it to tell me which plugin it is (Because the silly man left /pl available) and I should say that doing this could revolutionize Enchanter + Blacksmith
