All-Around Vision

Speed: 30 feet, climb 20 feet

Melee ◆ jaws +12 (reach 10 feet, unarmed), Damage 1d10+7 piercing

Melee ◆ tongue +12 (agile, reach 15 feet), Damage Tongue Grab

Tongue Grab If the giant chameleon hits a creature with a tongue Strike, that creature becomes Grabbed by the giant chameleon. The target isn't Immobilized, but it can't move beyond the reach of the giant chameleon's tongue. A creature can sever the tongue with an attack that hits AC 15 and deals at least 4 slashing damage. Though this doesn't deal any damage to the giant chameleon, it prevents it from using its tongue Strike until it regrows its tongue, which takes a week.
