The 火月怪 is a 困难模式, post-石巨人 敌怪 that is spawned by the 日耀柱 during the 月亮事件. It is a ground based enemy that has 2 flaming swords which curls up and flies at high speeds towards the player. When it does this, certain projectiles you have fired at it will be reflected. This is very dangerous as some weapons like the 狙击步枪 and 彩虹猫之刃 can potentially deal over 300 damage to the player.
- 部分剑的射弹, 诸如彩虹猫之刃和圣诞树剑, 但并非所有。(在下方列出)
- 寒霜九头蛇, 弩车,还有爆炸烈焰召唤的攻击
- 绝大多数远程武器的特殊攻击, 诸如幽灵凤凰的凤凰或者星旋机枪的特殊榴弹。
- When it spins, it reflects projectiles.
- It appears the Selenian's defense is greatly decreased when it spins.
- Reflected Chlorophyte Bullets will target the player. Due to this, they are inadvisable to be used versus the 日耀柱.
- Melee users shouldn't have too much trouble with this enemy provides they use a weapon that doesn't fire a projectile. Ranged users should use weapons that fire rockets, such as the 火箭发射器 or 手榴弹发射器. 仆从s that use melee attacks are good choices for mages and summoners.
- 吸血鬼刀 can be reflected, but if they hit the player they lose their "lifesteal" effect and the selenian will not regain health.
- The word 火月怪 means "lunar" and refers to Selene, the Roman goddess of the moon and sister of the sun-god Helios.
