Trying to figure out Doryani’s Prototype

Decided to use a Vaal Cultivation orb on a Doryani’s prototype cause it seems like a pretty sick “build around” item. The Orb replaced Max life with what is essentially leopold’s applause (hits can penetrate ele res down to a minimum of -50%)

The question here is, would that be redundant since I’m aiming for zero lightning res, or ridiculous in this case? Cause I’m not quite sure.
