Predecessor Builds > Kira > LOW TTK ON PRACTICE STEEL
Measured a bunch of build combos in practice against the steel bot without using the crest or ultimate ability, and found this build to be one of the lowest time to kills while having a lifesteal card for some sustain. Swapping for dust devil or imperator on either of the last two cards came out with somewhat similar results. sometimes I would get higher results with the main build due to the 75% crit rate. It usually came out to roughly a 1 second difference. Which still had it at about a 6-7 second kill time. The fastest I got was around 5.5 seconds. Swapping for dust or imperator usually came in around 5.8-6.5 second TTK. It essentially comes down to an attack speed build. The downside is you can't pick some other sustain cards. You could get the TTK even faster by swapping Terminus for Dust devil, but again at the cost of sustain. It would only work well on people that have excellent positioning and good peal. I haven't tried any of these variations in game so good luck if you try it!
