Rocket Charge: On Mjölnir there’s a thingy on the staff while on other Hammers on the Head of the Hammer.
Thunderclap: There’s the same, lighting on a normal Hammer comes from the top while Mjölnir from the bottom.
Graphical issue: if you wear Mjölnir and another player put the mouse on you the wielder will have a ghostly case around the character.
