Obsidian Trap

The Obsidian Wall Trap is a trap item found in the Deep Desert Caves. It can be wired using Wiring tools and items, making it suitable for automated defenses in player-built corridors and bases.

When activated, it fires two bursts of flame that travel up to 8 tiles and inflict the On fire debuff. The second burst appears 10 ticks, or 0.5 seconds, after the first, which lets the trap hit the same path twice in quick succession. It has a cooldown of 20 ticks, or 1 second, so it can trigger again fairly rapidly once reset.

Because it projects flame outward rather than dealing direct contact damage, the Obsidian Wall Trap is especially useful in narrow chokepoints where enemies are forced to pass through the line of fire. Wiring it into a timed or pressure-based defense allows it to contribute consistent damage and status application without requiring manual activation.
