Deep spores are knobby leathery globes 2-5 feet in diameter, sporting at least one large eye spot, that float about the dark deep underground realms and caves. They appear to hover as would a balloon but some are too heavy for this so sages speculate they possess the ability to levitate.

Different populations of deep spores react to different stimulus and when harmed of over stimulated will burst often hampering or harming those nearby. They are immune to all illusions except those of their specific stimulus, which they will save vs at -4. The stimulus selected below will attract all deep spores of the same population within range to detect it.
