Vampire Frog Staff

The Vampire Frog Staff is a ground melee summon weapon. It has a 12.5% chance to be dropped by a Zombie Merman and a 12.5% chance to be dropped by a Wandering Eye Fish, both of which spawn while fishing during a Blood Moon. It spawns a Vampire Frog minion that follows the player and melee-attacks enemies using its tongue. Like other minions, the summoned Vampire Frog is invincible and follow the player for an unlimited amount of time, unless the player dies, summons a replacement minion, or cancels the buff.

Its best modifier is Mythical. Unlike most summoning weapons the Mythical modifier provides an 18% damage boost due to rounding, making it on-par with the Ruthless modifier, along with its other stat bonuses.
