My first item suggestion fail so I've try again. Here's what I got:
Passive: Every 12s, you start charging damage for up to 10s. Your next basic attack will deal 40(+4 every second charge) true damage, double on jungle monster. Killing a unit will refresh the passive (which start at the 40 base damage). Killing a jungle monster will increase 1 damage per charge.
So basically this is another version of Quelling Blade but the passive changed. It is similar to Ashe/Thresh passive and the Feral Flare stack damage passive.
+10% Critical Chance
(Don't know if you want this in game)
Recipe: 2x Culling Blade + Gold
+20% Critical Chance
Passive: When crit, you attacks twice instead, each deals 100% AD.
(If increase crit damage to, for ex: 225%, it would increase each basic attack to 125% for a total of 250% instead).
This passive will allow for some 'AD carry' to comes to VotE which have effect base on basic attack (similar to Vayne or MF's W).
Axe of Chaos
Recipe: Hunter's Axe + Culling Blade
+30% Critical Chance
Passive: When crit you attacks twice instead, one deals 100% AD as physical damage, the other deal 100% AD as true damage.
Passive: After 6 basic attack, your next attack will crit.
This item works very well with: Storm Hammer, Rending Claws and any champ that have on-hit effect.
