Docker

Strategy
The Docker is the epitome of a bruiser in size 2 form. Hull Breaker outputs impressive damage per turn, with tokens only amplifying it's effects. Make Way, though used infrequently, is extremely disruptive to the team given it's coming from such a tanky monster. Brine Bucket, though not immediately threatening, applies Barnacles to combo with Make Way or other shuffle effects from the Fisherfolk.

However, with no DOT except for Barnacles, you could combat Dockers with conventional Tanks like Man At Arms or Leper with Taunt. Alternatively, pushing the Docker backwards by effects such as Rampart or Daemon's Pull on other enemies could force the Docker out of range for it's 2 main abilities, Make Way and Hull Breaker. Brine Bucket, though definitely nothing to sneeze at, is significantly less dangerous than a Crit from Hull Breaker, as well as disrupting the other Fisherfolk that could need the back ranks.

Like most Size 2 enemies, choose either to deal with the Docker first or last, as while it's high damage is a major variable in the fight he spawns in, other enemies such as Fishmonger's bleed or Captain's Token generation can take priority.
