Before & After 0.4.0 from POE2DB


As part of the 0.4.0 patch with the added "Spectre buffs," it seems like the secondary damage from the Ancient Ezomyte's lightning arrow was changed from pure lightning spell damage to attack physical damage. This doesn't seem to be intentional because the attack physical damage still retains the increased chance to shock without any physical to lightning conversion and the fact that the patch notes only mentions changing the spell to attack type, not a change in the elemental damage type.

My in-game testing somewhat reflects this change, as it is incredibly hard to shock enemies before killing them, but stunning them is very easy. This is a sharp contrast to other lightning spectres I've used like Powered Zealots.
