Black Recluse

The Black Recluse is a Hardmode enemy that spawns in Spider Caves, but can rarely be found in the Cavern layer outside of its caves. It can inflict the Venom debuff. In, it gains a special spit attack that applies the Webbed debuff to players.

Tips

 * With their black color, Black Recluses may be difficult to perceive in the Spider Cave. It is advisable to place an ample number of light sources.
 * Their high damage output combined with their property of being difficult to see and chance to inflict the Venom debuff for an additional 40 damage makes them extremely deadly and can easily kill players in early Hardmode.
 * Because of their low health and high defense, using weapons that deal a lot of damage with a single strike is the best way of defeating them. High-knockback weapons can also hold them off for long enough to get them killed.
 * A good weapon to use on a Black Recluse is a, as it can deal damage to it from a safe distance.
 * Once the player has better weapons, Black Recluses are an excellent money-farming target, offering over half a Gold Coin per kill. They drop up front, the chance of a Poison Staff averages about  per kill, and the fangs can be crafted into Queen Spider Staffs averaging  per kill.

Trivia

 * The name Black Recluse is a combination of the spider names ' and '. Both spiders are commonly known for their venomous capabilities. This is reflected in the enemy's appearance, drops, and Venom debuff infliction.
 * The cooldown of the web spit attack is programmed in a way that it could technically last up to 15 seconds: Every tick✅, the game checks whether the last attack occurred longer than $$x$$ ticks ago, $$x$$ being a number between 180 and 899 randomly picked upon every check. If that is the case, the cooldown is reset and the Black Recluse fires again. Therefore, the cooldown will always last at least 181 ticks (which is equal to 3 seconds), but will exceed a couple ticks more than that in only extremely rare cases – see the :

 * It can be seen that the chance for the cooldown to last only 10 ticks longer than 181 ticks is extremely low, way outside the scope of even the rarest item drop chances.
 * Consequently, the chance that the cooldown lasts 899 ticks, or 15 seconds, is so unimaginably low (approx. 5.26 × 10-2058) that it is virtually zero.
