Does repeating crossbow stack??
Repeating Crossbow, 
+
, has the effect:
"On death, this jumps to an allied champion and grants an additional 20% Attack Speed & Critical Strike chance."
Additional meaning it give 40% AS & crit after one jump, and 60% after two jumps, etc? Or "additional" meaning 20% more than their base stats? I've seen a number of people saying it increases each jump, but when I check the crit of who it jumps to, it always looks like it's giving only 20% crit.
