We have session based cursed cannonballs that give limited harmful effects on ships/players when activated.
Let's have different types of grog that we can consume for limited beneficial effects for players.
Maybe a type of grog that allows you to move sightly faster whilst carrying a chest for a few minutes making unloading just a little bit quicker? Faster swimming for a few minutes? Less fall damage? Further sword lunges for a minute etc.
These are just some basic ideas, but it could easily be expanded and fleshed out to change other gameplay elements in weird and exciting ways.
The different types could be purchasable from every outpost and available to everyone, giving people some reason to visit the taverns! Perhaps it could be available ONLY to pirate legends through the tavern at the hideout?
Pirates have the reputation of loving their grog, and giving players some incentive to empty their tankards more often could be fun!
