Due to the limited number of items in a unit (3), of course Repeating Crossbow could not re-equip fully equipped units. If it was the last unit, then Repeating Crossbow will disappear.
Stats: 20% critical strike chance and 20% attack speed.
Passive: When the wearer dies, Repeating Crossbow is re-equipped to a new ally. Each time the item is re-equipped, it grants an additional 20% attack and 20% critical strike chance for the remainder of combat. This effect can stack any number of times.
