Nymph

The Nymph is a rare enemy that spawns in the caverns. When first encountered, it will appear with the name Lost Girl and pretend to be a helpless NPC that needs to be saved. When you get close, however, it will transform and attack as a Nymph. This enemy is extremely dangerous, since most new players will not know about this enemy. They do high amounts of damage, but it is possible to shoot them before they transform with either a ranged or a magical weapon. Nymph cannot jump very high, so you should climb on top of a wall and attack down, or staying behind walls. The Nymph is very hard to find. After the first encounter, however, it won't appear as a lost girl again.

Tips

 * It is recommended that players with low-end equipment take caution around or avoid these enemies, as they are very difficult to defeat and do high amounts of damage to weaker players. If you must engage, it is recomended that you use a ranged weapon.
 * Nymph uses standard Fighter AI. She can't jump very high or go through walls, so players can use this to their advantage by staying behind walls or on top of tall cliffs. Even with weak throwing weapons, it's easy to stay completely out of her range while still dealing damage.
 * Minions and other enemy seeking weapons will target the Lost Girl before she transforms into a Nymph.
 * It is easier to fight with the Harpoon, as it can be stun locked.

Trivia

 * The Lost Girl appears to be completely naked, which is a unique trait amongst all humanoid NPCs.
 * Unlike in Terraria, a nymph in Greek and Latin mythology is a lesser female deity with the power to animate nature.
 * The name Lost Girl could be a possible reference to the Canadian supernatural crime drama television series Lost Girl, where nymphs are a type of supernatural beings.
