I think there may be a bug with varus passive
I was creating a new build for varus based on AS. The item i had where Botrk, AS boots , And Hurricane. For and total for 115 As and the AS mastery with 3 qunits for AS. The problem was when i proc varus passives on and minion at the time AS was 1.75 it turned into 1.88. That number did not seem right so i did some calculation to check what was the error was. The Actual AS is to be 2.1 instead of 1.88 Since, 20% of 1.75 is 0.35 not 0.13 ,which the system is adding to overall AS. Hopefully its just a bug that can be fix by patch 7.1. Thanks for reading this and have a nice day. P.s ignore all the grammar and typos I`m half a sleep when writing this.
