When killed, a cave spider will drop
- 0–2 String. The maximum is increased by 1 per level of Looting, for a maximum of 0-5 string with Looting III.
- 5 experience when killed by a player or tamed wolf.
They also have a 1⁄3 chance of dropping a spider eye when killed by a player or tamed wolf. The maximum amount of spider eyes is increased by 1 per level of Looting. The chance of a cave spider not dropping any spider eyes can be found using the formula
2 / (Looting Level + 3). For example, Looting III gives a 1⁄3 chance of not dropping any spider eyes. All other amounts have an equal chance of occurring.
Cave spiders inherit most of their behavior from regular spiders:
- Neutral under daylight or in light levels of 9 or above, otherwise they are hostile. However, once they become hostile, light does not affect them.
- Can climb walls when needed.
- Attack by leaping at their targeted entity.
- Are unaffected by cobwebs and poison.
- Can spawn spider jockeys in the Bedrock Edition.
However, they have some distinctions from regular spiders:
- Can fit through a space that is one block wide and ½ block tall.
- Can go through the spaces between two different types of (unconnected) fences.
- Cannot spawn with status effects.
On normal or hard difficulty, cave spiders inflict Poison upon attacking. On normal difficulty, the poison lasts for 7 seconds and can cause up to 4 damage. On hard difficulty, it lasts for 15 seconds and can cause up to 10 damage. Note that even on hard, poison damage is not taken when health is at 1.
Cave spiders have entity data associated with them that contain various properties of the mob.
