Predecessor Builds > Kira > KIRA CRIT
I like to start off with Q then E. Aside from Q's damage, its slow helps get those early hits in. E helps close in on the slowed enemy or escape danger. RMB isnt all that great early on so I add it 3rd.
Max Q first
Max RMB second
Max E Last
Always upgrade R when you can
I've had a lot of fun playing this build. Focuses on a balance of on-hit, crit damage, and sustain. Also great for racking up CS and dealing constant hard hitting damage. Hope it works well for you guys.
When you cant buy anything else dont forget to get the Tonics in the shop
