**Amorphous.** The Gray Ooze can move through a 1 inch space without squeezing.
**Corrode Metal.** Any non-magical weapon made of metal that hits the Gray Ooze corrodes. After dealing damage, the weapon takes a permanent and cumulative -1 penalty to its damage rolls. If the penalty drops to -5, the weapon is destroyed. Non-magical ammo made of metal that hits the ooze is destroyed after dealing damage.
**False Appearance.** While the Gray Ooze remains still, it is indistinguishable from wet rock or an oily pool. It has *advantage* to stealth checks made in cavernous spaces.
