Magma Glob. Ranged Weapon Attack. +15 to hit, reach 60/240 ft., one target. Hit: 38 (7d10) fire damage and the space it is in, is covered in lava for 24 hours before

cooling. On a miss, an unoccupied space within 5 feet of the target is covered in lava. The lava ignites flammable objects in the area that aren't being worn or carried and creatures that starts its turn in the lava or enters the space for the first time on a turn, takes 11 (2d10) fire damage.

Crush. The dire miralis slams its body on the ground in a 40-foot square in front of it. Each creature in that area must succeed on a DC 23 Strength or Dexterity saving throw (target's choice) or be knocked prone and take 18 (4d8) bludgeoning damage plus 31 (7d8) fire damage. On a successful save, the creature takes only half the damage, isn't knocked prone, and is pushed 5 feet out of the dire miralis's space into an unoccupied space of the creature's choice. If no unoccupied space is within range, the creature instead falls prone in the dire miralis's space.

Each creature in a 25-foot radius sphere centered on that point must make a DC 23 Dexterity saving throw, taking 77 (22d6) fire damage on a failed save, or half as much damage on a successful one.
