Elmer's Sticky Brew

Sticky glue covers the ground and then quickly hardens inside a 10-foot radius centered on a point within range, turning it into difficult terrain for the duration

When the glue appears, each creature standing in its area must succeed on a Strength saving throw or become restrained around the ankles and shoulders. A The restrained creature’s speed becomes 0, and it can’t benefit from any bonus to its speed.
Attack rolls against the creature have advantage, and the creature’s attack rolls have disadvantage.
The creature has disadvantage on Dexterity saving throws.

Once the creature has succeeded a Strength saving throw, they can no longer become restrained by the spells effect.
