Clinger

The Clinger is a mob that behaves like Man Eaters, extending their head to damage the player. Unlike Man Eaters, however, Clingers spit green flames (That resemble Cursed Flames if they were unaffected by Gravity) if the player is out of their immediate reach.

They have 320 health, have a ranged attack damage of 22, 70 melee damage and 30 defense. They spawn in the Underground Corruption after defeating the Wall of Flesh. This mob is also only very slightly affected by knockback. When hit by a Clinger's fireball, the Cursed Inferno debuff may be applied.

When approaching a Clinger, care should be taken. Its flaming projectile is quite dangerous as the debuff it applies can't be put out with water. To avoid becoming charbroiled, ranged weapons are recommended, or if you're desperate; bombs will suffice. When up close, swing at them with your most powerful melee weapon while staying out of their range of attack. There is also a bug where a clinger can attack a player offscreen and then disappear.

A Clinger can be prevented from attacking with its cursed flame attack by repeatedly doing damage to it. Setting it on fire also seems to work. Clingers cursed flame projectile can't be blocked (aka broke) with melee attacks, bullets from ranged weapons or with magical projectiles.
