I was actually testing it as I was writing this feedback. Even posted a relevant build. And Ronaprax amulet seems to be tailor made for that build. However, I ended up dropping it because it because it loses to every other option. Pestilence of Dreeg, for example is a much much stronger offensive option.
A bit off-top, but I ended up dropping RTA Dreeg’s Evil Eye altogether too, just doesn’t work well unfortunately.
