There have been plenty of mods over the last two years or so that add in new classes, but less prevalent have been whole new monsters and bosses. A series of mods from ActionJack aim to rectify that problem, taking up the noble goal of providing new creatures to messily devour your heroes (or drive them mad, of course).
The Kraken mod adds five new common aquatic-themed enemies to the Cove area, along with a brand new tentacled boss. As with most DD bosses, this one will take some strategy and forethought to avoid a total party wipe. Get ready to meet a Captain Jack Sparrow style end!
