[1.1.3.0] AAR vs FoI (Deceiver, Mage Hunter, Purifier, Spellbinder, Warlock) (c+) (sr+) (g3)

hey,
since this is an old build, are there any possible improvements for the AAR warlock ?
link for convenience https://www.grimtools.com/calc/m23JEb4N

ring of tawrot wouldn’t be a better option for either ring, right? damage gets converted only once right?
does this count on any conversion? like the global % conversion and the 100% per skill conversion?
i’m assuming the 100% lightning to vit on AAR conversion of the hat, won’t be converted by the ring of tawrot. am i assuming correct ?

i like this build a lot, but after testing the chaos ray warlock from retal abuser


i’m hoping for some improvements, because i don’t really want to use this, and i’m ok with the other being weaker, but almost 100k more AAR dps is something.

cheers
