The maw demon, a wind-it-up-and-let-it-go battlefield hazard of the Abyss sometimes found in the company of gnolls, loses the Rampage trait (and, thus, much of its connection to gnollkind) and gains Disgorge, a projectile vomit attack. Charming. This action recharges only on a roll of 6, meaning the maw demon will most likely get to use it only once per combat encounter. Since it’s stupid and erratic, the maw demon won’t wait for a better opportunity to use it than the first one it gets, so its nature impels it to move straight toward any group of three or more foes clustered together in a 15-foot cubical area and vomit as soon as it arrives. If it gets a chance to do it again, it will, but that’s not probable.
The babau’s Multiattack is dialed back: formerly comprising Weakening Gaze and two melee attacks (either Claw or Spear), it now comprises only two Claw attacks, one of which it can replace with Weakening Gaze or a Spell. The Spear attack is gone, which is fine; the babau didn’t need it. Its spell list is left intact.
The flaw inherent in Weakening Gaze remains: It’s primarily useful against enemies who are likely to have the Constitution to resist it. And the tactical conclusion remains: Use it against paladins and fighting clerics, because at least they don’t have proficiency in Constitution saving throws. Fear is still likely to fail, but the fact that it costs only one Claw attack, rather than an entire action, makes it a somewhat less pointless gamble against three or more targets within its area of effect. For the same reason, darkness is a better deal than it was before, particularly against a party that contains neither a paladin nor a battle cleric. And heat metal is dramatically better, since it can now be combined with a Claw attack for up to three dice of damage plus the babau’s Strength bonus. If none of these options makes sense, default back to two Claw attacks.
