Deadstone Cleft Stone Giant

The giant meditates for 1 hour, during which time it can do nothing else. At the end of the hour, provided the giant's meditation has been uninterrupted, it becomes petrified for 8 hours. At the end of this time, the giant is no longer petrified and gains tremorsense out to a range of 30 feet, as well as a measure of innate spellcasting ability for the next 24 hours.

The giant has advantage on Dexterity (Stealth) checks made to hide in rocky terrain.

The giant's innate spellcasting ability is Wisdom. It can innately cast the following spells, requiring no material components:

3/day each: meld into stone, stone shape

1/day each: stoneskin, time stop

The giant makes two greatclub attacks.

Melee Weapon Attack: +9 to hit, reach 15 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage.

Ranged Weapon Attack: +9 to hit, range 60/240 ft., one target. Hit: 28 (4d10 + 6) bludgeoning damage. If the target is a creature, it must succeed on a DC 17 Strength saving throw or be knocked prone.

If a rock or similar object is hurled at the giant, the giant can, with a successful DC 10 Dexterity saving throw, catch the missile and take no bludgeoning damage from it.
