it would be nice if we could link an item to a specific monster , either through the PrEditor or through editing the text files
so if I create a monster names jamesL and I make that monster a boss, it would nice if I could also create a unique item, a ring for example, named JamesL's Ring Of Longevity (10% faaster HP recovery and +45 to life)
and then when the player kills the boss there is chance he'll drop the ring, so it'll be like a special trophy
so that means
the ability to create a monster that will show up only once (part of the definition of champion / boss)
the ability to create an item that will show up only once (a true unique)
the ability to have that item drop only from that monster, or as a reward for completing a specific quest (a true trophy)
it wouldn't have to drop every time, but it would be nice if we could set the chance to drop
the monster doesn't have to equip the item, just be able to drop it (though having the monster equip it might be interesting too, seeing the monster actually using "The Sword of Flaming Death" against me, then I kill him and take it from him)
