The Succubus is the second boss in Despairing Souls.
The Succubus summons a Goblin and a Leraje. The Leraje can shoot twin bullets and jump, while the Goblin simply follows you. The Goblin has 300 HP and the Leraje has 500.
The Succubus wields a poison flower, and has two attacks: it can whack you with the rose, dealing poison damage, or it can spray flower petals everywhere. Aside from that, the Succubus can punch you, and floats. She has 800 HP. The theme for the two battles are Death Flower Succubus.
