Multiattack

A tophet makes two attacks, no more than one of which can be a gout of flame.

Slam

Melee Weapon Attack. +10 to hit, reach 5 ft., one target. Hit: 12 (1d10+7) bludgeoning damage. The target is also knocked inside the tophet's burning belly if the attack scores a critical hit.

Gout of Flame

The tophet targets a point within 100 feet of itself that it can see. All targets within 10 feet of that point take 22 (4d10) fire damage, or half damage with a successful DC 16 Dexterity saving throw.
