Caitiff Staff is a rare, moderately enchanted (+2) special variant of the Quarterstaves family of weapons. It is a simple melee weapon that can be wielded in one hand, or with both hands for extra damage.
The texture of magic granted by a warlock's patron is largely dependent upon the patron themselves - for example, your standard eldritch patron's probably going to work some eyeball-mottled tentacles in there somewhere.
