Rod of Dark Purpose

Rod, very rare (requires attunement)

This rod looks like it’s made from jagged obsidian and it functions as a magic mace that grants a +2 bonus to attack and damage rolls. The rod of dark purpose is gifted to only the most dedicated warlock servants. This rod allows the warlock to double their damage for the eldritch blast spell a number of times per day equal to double his or her Charisma modifier. A non-warlock who can cast eldritch blast can double their damage a number of times per day equal to their Charisma modifier or if the character can’t cast eldritch blast gains the ability to cast the spell a number of times per day equal to their Charisma modifier using their Charisma modifier and proficiency bonus for the attack roll. This rod also serves a more sinister purpose. If the rod is attuned to a different user, the last user is teleported to the foot of the rod’s creator for punishment. The rods uses replenish after a long rest.
