Patch history
2 changesFixed a bug with Herald of Plague where anything that caused the ongoing buff to recalculate, such as changing the reservation amount, caused it to add the base spread radius to itself again.
Herald of Plague now requires a Martial Weapon, making it consistent with the weapon restrictions of the other Herald skills.
