League of Legends’ Gragas’s full title is “Gragas, the Rabble Rouser,” because he’s known to rouse a few rabbles. This mostly comes when he’s drinking, and since every single one of his abilities is enhanced, in some way, be alcohol, it means plenty of rabble rousing. The oaf’s passive skill is called Happy Hour, and makes it so he “takes a drink from his cask every time he uses an ability, restoring 2% of his maximum health over 4 seconds.”
If that was his only link to booze he’d still make the list, but there’s plenty more where that came from. His other attacks? One has him rolling a cask of ale at his enemies that blows up after a few seconds, another involves throwing said cask and creating a gigantic explosion, while another has him guzzling his brew in a move called “Drunken haze.” His last ability is a charge that slams into enemies, and while it’s not technically related to booze, it certainly doesn’t sound like something someone sober would do.
