The Dank Staff is a craftable Pre-Hardmodesummon weapon that can also be dropped by The Hive Mind. It is statistically identical to its Crimson counterpart, the Blood Clot Staff. When used, it summons a small dank creeper minion, which deals contact damage and will stay on enemies for as long as possible.
Its best modifier is Mythical. While Ruthless may seem to provide a bigger damage by percentages, rounding reveals that Mythical and Ruthless boost the damage equally for this weapon.
The Dank Staff is very helpful for multiple enemies stacked in one location, so it can be good for invasions.
Although its base damage is lower than other summons of the same tier, the dank creeper's tendency to hover on top of enemies causes it to deal damage rapidly.
