Invoked [Cost: 2] - When invoked, this rune causes the ground beneath the rune in a 15 ft. radius to tremor and shake violently, making the area difficult terrain. Additionally, creatures within the area must succeed on a Dexterity saving throw at the start of each of their turns or fall prone. Creatures within the affected area that are concentrating on spells at the time the rune is initially cast must succeed on a Constitution saving throw or have their concentration broken. This effect requires concentration and lasts for up to 1 minute.

Scribed [Cost: 4] - When scribed onto an object or creature, this rune causes the scribed object or creature to harden, becoming more resilient to damage and giving it the texture of stone. The affected object or creature has resistance to bludgeoning, piercing, and slashing damage. Additionally, the affected object or creature gains a number of temporary hit points equal to your Rune Potency at the start of each of your turns. This effect requires concentration and lasts until dismissed or dispelled.

Synthesis [Cost: 2] - Combining this rune with the effects of a scribed or invoked rune that requires concentration gives the caster advantage to concentration checks for the scribed or invoked rune's effects.
