AS benifits TBT and IE equally, AD and Crit scale more with IE damage wise, but TBT heals you for more with those stats.

In the end, TBT costs 3200 gold, which this + Vamp costs 4,600. You also lose 20 AD and 8% LS, for an effective 40% damage increase on AA (That's how much 25% crit with 2.6 crit modifier increases your damage on AA).

Worth it? Pros think not, because the sustain and cheapness of TBT is hard to pass up.
