Atlas' Burden

Choose up to 5 creatures within 60 feet. Each target must succeed on a Strength saving throw or be affected by the spell for its duration. 

An affected target's speed is reduced by 10 and it takes a -2 penalty to AC and Dexterity Saving Throws. Flying creatures fall to the ground at the end of their turn. On affected creatures turns, all attacks made with a melee weapon are at disadvantage. All attacks made with a ranged weapon are made with range increments halved. 

A creature affected by this spell makes another Strength saving throw at the end of its turn. On a successful save, the creature is no longer affected.
