Predecessor Builds > Kira > Kira Crit Build
unlock and max RMB first and get ur dash 2nd against ganks. Once u hit lv 6 ur ult is a menace so think about abilities that can interrupt it and only use ur Ult if you see those enemy abilities on Cooldown. Your Ultimate goes through walls so try to play around gold buff or the pillars as much as you can. Twinblasts ultimate should be easy to evade as long as you have ur dash and are near a wall/pillar.
Special 1: Kingsbanes on hit passive works with ur ultimate and RMB so u will heal a lot once u have that item. If you really enjoy getting value out of kira ult and theres not much to stop u on the enemy team, then get terminus 2nd instead of demolisher, and get demolisher as last item and replace kingsbane.
Special 2: Crest you mostly want to go for liberator (universal), Witchstalker (against Sev: cleanse his root and hit him with dmg boosted), Pacifier (against Crunch or Steel: use to create distance or dodge Steel Ult).
