which doesn't stack with those orbs and 9% crit from past lives for fire/cold/acid/elec/sonic and the Sharn orbs basically exist to compensate null and radiant for lacking energy criticals while additionally hard restricting gear slots for neg/poison/light casters.
Those orbs are the opposite of a boon, they're a crutch to prop up the system poorly supporting those elements while also restricting the gearsets for those elements and with how gearsets are so fixated around stacking multiple set bonuses the sharn orb situation and SSG refusing to make more recent alternatives is leaving those elements in a bad spot.
