Stone Rune (Tourmali Tree)

Twice per long rest you can bind a stone rune onto a flat surface. Each rune has a command word (which you assign to it), when the command word is said it activates. The stone rune can do one of three things (decided by the player while casting):

• Rock Barrage. Rocks begin to fly from the rune. all creatures within a 20 ft. cone must succeed a DC 14 Dexterity saving throw or take 2d12 bludgeoning damage.
• Stone Grasp. A stone hand erupts from the rune and grabs the nearest creature within 5 ft. of the rune. The creature must succeed a DC 14 Strength saving throw or be grappled until the hand is destroyed or dispelled using counterspell, dispel magic, or wish. The hand has 5 hit points and an AC of 15.
• Repelling Tremor. All creatures within a 30 ft. line from the face of the rune must succeed a DC 14 Strength saving throw. Upon failure, the creatures are moved 10 ft. away from the rune and knocked prone.
