how can I make it when I drag an item (upgrade shard), onto an equipment item, it does the event of "take equipment item & upgrade shar and give Equipment item +1"?

There's no dragging and dropping for this unless you write that in yourself. The "easiest" way to do it without any changes to intersect itself would likely be the solution proposed by BabyLoves

Do you need make two equipments:

Wild Bow(+0)

and 

Wild Bow +1

For forge the Wild Bow +1 the player need Wild Bow +0 and 10 other items...
