Echo Block

Tooltip: "Only visible with Echo Sight" The Echo Block is a translucent block which turns completely invisible once placed. Echo Blocks are sold by the Cyborg NPC only when he is housed in a Graveyard Biome. Once placed, the Echo block cannot be seen by the player unless they have the Spectre Goggles equipped. The Spectre Goggles is an accessory item which when equipped, allows the player to seen all placed Echo blocks.

The Spectre Goggles are also sold by the Cyborg when he is housed in a Graveyard Biome. Echo Blocks work similarly to most blocks as they can be hammered, actuated with an Actuator, and aren't able to be passed through by normal means. ( The player cannot go through Echo Blocks even when invisible )
