- Not to be confused with 蛾.
蛾怪 is a powerful flying 敌怪 that spawns during the 日食 event and passes through 物块s. It can only spawn after all 机械 Boss have been defeated. Mothron attacks by lunging at the player. Occasionally it lands on blocks to lay several Mothron Eggs that will spawn Baby Mothrons if they are not destroyed in time, much like 天兔.
- Broken Hero Sword and The Eye of Cthulhu item drops are mutually exclusive, i.e. there is 25% chance for either item and 50% chance for none of them.
- The basic steps:
- Prepare an open, flat arena.
- Equip a good set of 翅膀, and either Hallowed armor with helmet (which gives a ranged bonus and ranged critical strike chance) or Chlorophyte armor with helmet (which gives a ranged bonus, and each crystal leaf projectile will deal 100 damage) or 蘑菇矿盔甲. 海龟盔甲 and 甲虫盔甲 offer more defense, but they're better suited for melee, and offer no ranged bonuses.
- Ranged and Magic weapons are ideal. The 食人鱼枪's projectile damages any enemy it comes in contact with while still latched to the target (can be defeated in 20-25 seconds in normal mode, 40-45 seconds in Expert mode). Also good choices are the 巨兽鲨 and the 邪恶三叉戟 (except for its high mana cost) , Also 水晶蛇 is a viable choice due to the splash projectiles, or for melee users, any 断裂英雄剑 made weapon (泰拉刃, 原版断钢剑, 原版永夜刃), 悠悠球 such as 克拉肯球 or 克苏鲁之眼.
- Ranged damage boosting 配饰 (for melee users, melee boosting accessories).
- You can run from Mothron while firing Light Discs or 魔法飞刀 at it.
- If this is done on a flat area, it can be effective.
- Mothron is most vulnerable when it's laying its eggs.
- Mothron is a reference to Mothra from the namesake 1961 movie. The subtle change in its name follows the trend of Terraria enemies' and bosses' names ending with the suffix -ron, such as 骷髅王, 猪龙鱼公爵, and 猪龙.
- If the Eclipse finishes, or all players die, Mothron floats up to the sky and despawns, similar to the Martian Saucer and Pumpkin/Frost Moon Event Bosses. In addition, it becomes invincible after the end of the Eclipse.
