Prerequisite: 4th Level, Strike of the Giants (Stone Giant) Feat

You’ve manifested the physical talents emblematic of stone giants, granting you the following benefits:

Ability Score Increase. Increase your Strength, Constitution, or Wisdom score by 1, to a maximum of 20.

Stone Throw. As a bonus action, you can touch a rock that can fit in the palm of your hand and imbue it with magic. While the rock is imbued with magic and you are wielding it, the rock is a magic ranged weapon with which you’re proficient, and it has the thrown property with a normal range of 60 feet and a long range of 180 feet. On a hit, the rock deals 1d10 bludgeoning damage, and if the target is a creature, it must succeed on a Strength saving throw (DC equals 8 + your proficiency bonus + the modifier of the ability increased by this feat) or be knocked prone. The magic remains in the rock until you hit with it or finish a long rest. You can imbue a number of rocks equal to your proficiency bonus with this bonus action, and you regain all expended uses when you finish a long rest.

Cavernous Sight. You gain darkvision out to a range of 60 feet. If you already have darkvision from another source, its range increases by 60 feet.
