JANITOR NASUS
so i was thinking why not have a janitor nasus? so his staff can be a mop and when he walks its like he is carrying a mop and a bucket but when he runs his mop is on the floor in front of him and there is like soapy water particle effects in front of him.
so his E would be like a puddle of water that says dont run W would be like he soaps someone and the enemy champ has a trrail of bubbles Q would be like pouring a bucket on someone and his ult is just an angry janitor :D
EDIT: Here is another idea proposed by @Gjom to have a Janitor
