[@MonsieurShade]This might clear that up but I dunno

Jacks power to command ink allows him to create any entity and bring it to life as he wishes,he can also turn his entire body into ink which opens up the power to shapeshift

Examples of things jack could create(extend to but is not limited to)
Swords
Vehicles
Armor
Firearms
Crossbows
Shields

Monsters
Demons
Animals
Thralls

And anything in between, again this is not his limit, I can't exactly think of a limit for a power that allows you to Flipping create what ever dafuq you want to create and more.
