people always hate the best skills, especially when its not really unfair to call ternion unbalanced.
nevertheless i would go for max VO, but im not a big fan of the core dweller upgrades(except the last one) usually i want my dweller to soak the damage, i would never consider putting more than one point into his attack spell. i can see maxing the liche king is worth though usually he shoots himself out of energy with the arcane blast so that he can barely use the death nova. i wouldnt say that death nova is useless however so ill leave that up to you
btw if you actually go for ternion, ignore VO ;-)
