The Plank is a melee weapon boasting close combat ranges with high critical strike chances. It is directly unlocked during the campaign level "Spaced Out"
Using attack one, the player strikes the plank in a sideways motion dealing low damage. However when using attack two, the plank strikes down in a vertical motion dealing a much higher damage output.
The damage of the plank depends upon area of hit and luck. It is by far one of the top damage dealers in the game for melee weapons due to its ability to 2 hit KO enemies or deal significant damage.
