Ok, so basically this is a broken version of the original Phantom hit. Both items multiply onhit damage, phantom hit by 1.5x, this item by 1.3-2.5x. The good thing about your Kritaliser is that it doesn't screw up utility based 3 hit mechanics like Xin's and Aatrox's heal. The bad thing is, that it is potentially even stronger than the original version for all damaging onhits. It is also more volatile due to how crit works.   This item and IE on yasuo for instance would bump his crit to 100%, while leaving 4 item slots open. fervor of battle alone would give him enough damage to go full tank (maybe slap in titanic hydra for fun). It's also a way for Vayne to boost her damage, while still allowing her to take down squishies through keeping her crit build open.   The idea is interesting, but I think that on hit as a stat currently has too much variables to give any multipliers.
