Conjure Minor Elementals Redux

You summon elemental spirits that float around you for the duration. Until the spell ends, the first time on each turn you deal damage to a creature, the attack deals an additional 2d6 damage when you hit a creature within 15 feet of you. This damage is bludgeoning, cold, fire, or lightning (your choice when you first cast the spell).

In addition, whenever a creature enters the space of the elementals or starts their turn there, they must succeed on a Strength saving throw or be pulled up to 5 feet either away or towards you (your choice).

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 and the range of the difficult terrain increases by 5 feet for each slot level above 4th.
