Last time I was playing greed mode with Lilith I came upon Blood Clot pickup which normally causes a character to shoot one normal tear and one damage-enhanced alternately.
I know that in case of Cain for example (as he doesn't have one eye/wears an eyepatch) this is changed to randomly shoot red and normal tears without alteration, but Lilith's default familiar only shot normal tears, and damage was not increased anyhow as per Missing HUD2 addon statistics, hence rendering this item useless.
I want to limit out buying items that won't affect Lilith, even though they could somehow (as it is with Cain).
So the question is:
TL;DR: What items do not affect Lilith in any way, even though they could (literally thinking)?
