Just build an eve if you want sustain…
True. I just find aftershock can save you when you’re in those tight spots with a squishy hero and you run out of eve points. That’s the main draw for me: instead of building defensive items, if they have a skillset that procs aftershock often and enough dmg, build eve and aftershock together.
Of course there are situations where only one is best but I find you can stay in fights longer, roam longer, and skip treants more with the both of them on squishy heroes.
