  • The maximum number of spider mines a player can have at anytime is 10. As with most other summons, the spider mines will be destroyed when the player travels to a different area, or when summoning more than 10 units.

  • The name and appearance of the spider mines suggests that they are a reference to the special ability of the Vulture in the original Starfcraft RTS.
