It can't be right as magic missile cast at lv 9 only does a max of something like 55 damage. With this setup you would one shot a room of beholders if cast at level 9.
11d4+11 + 11d4 + 11d6 = 55 + 44 + 66 = 165 max damage lol potentially 2 shotting an ancient red dragon CR24. Quite sad now
but yeah this has to change. Still that psychic bolt necklace is still a pretty amazing buff for a spell that cannot miss. Just read the D&D 5e definition of hex and it is only supposed to work on an "attack" so it shouldn't even work with eldritch blast as it is classed as a evocation spell.
Conclusion? hex is broken.
