Talk:Winter 2016 Event/@comment-42.117.50.189-20160215154341/@comment-27240709-20160215160312

It's listed as 0.6% (on easy), 0.7% (on hard) of all S-ranks at node L, but that's artificially low because you can only have 1 copy of Graf. Players who have her from the last event would still clear the node but will never be able to get her as a drop.

I'd guess her actual drop to be maybe 1 to 1.5% on easy, which would be inline with the other rare drops.
