Spider Castle Wall Trap

Spider Castle Wall Trap is a trap item found in the Spider Castle Incursion that fires an arrow when triggered. It is a placeable defensive object meant to be integrated into wired setups, making it useful for reinforcing corridors and chokepoints inside the castle.

The trap can be wired using Wiring tools and items, allowing it to be activated as part of a larger automated defense system. It has a range of 13 tiles and a cooldown of 20 ticks; this means it can fire once per second, so it works best when placed where enemies are forced to approach in a steady line rather than in large groups all at once.

• Because it fires an arrow, it is most effective when aimed down narrow paths or across doors and hallways.
• Its wired activation lets it be combined with switches, pressure-based setups, or other timed defenses.
• The 1-second cooldown makes it a reliable recurring hazard, but it is not a rapid-fire defense.
• Its value is highest in Spider Castle layouts, where enemies can be funneled into predictable movement patterns.
