Elaina's First Stone

When a creature is struck, you may strike in turn. When a hostile creature within 30 feet of you damages another creature, you may make a ranged spell attack against them. On a hit, the target takes force damage equal to 2d6 + your spellcasting modifier. If you have not previously damaged the target this round, the target also has disadvantage on attack rolls and Constitution saving throws until the end of their next turn.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot above the 1st.
