Abyssal Pressure

You call forth the deep within, surrounding yourself with incredible pressure to obstruct your foes. You summon an aura of the deep around you for 30 ft. and it does the following things:

• Every creature in the aura must make a Strength check every round they are affected: on a failed throw they fall prone for 1 round, on a successful throw nothing happens.
• Every creature in the aura's movement speed is halved each round they are affected.
