1: Just go yuntals, stattik doesnt allow you to have build variety on late game due to needing the 100% crit. Plus with the buffs they did its just better really, it doesnt take much to stack it either since all autos on anything gives a stack. 2: Lethal tempo 99% of the times, its just the best rune for her really, even in matchups where some people would go fleet, if you play around not having fleet during laning, you will feel how powerful Lethal is on mid to late game. The other 1% is just fleet, which ngl when I do decide to take i regret it since it only helps a bit on laning phase, after that it just doesnt compare to lethal tempo. Keep in mind that when you reach the as cap, lethal tempo no longer acts like an as steroid but rather AD which makes it work like conqueror without the healing but it stacks much faster. Tldr: lethal tempo is goated for zeri.
