Construct Spirit

A creature that hits the spirit with a melee attack or that starts its turn in a grapple with the spirit takes 1d10 Fire damage.

When a creature starts its turn within 10 feet of the spirit, the spirit can target it with magical energy if the spirit can see it. Wisdom Saving Throw: DC equals your spell save DC, the target. Failure: Until the start of its next turn, the target can't make Opportunity Attacks, and its Speed is halved.

The spirit makes a number of Slam attacks equal to half this spell's level (round down).

Melee Attack Roll: Bonus equals your spell attack modifier, reach 5 ft. Hit: 1d8 + 4 + the spell's level Bludgeoning damage.

Trigger: The spirit takes damage from a creature. Response: The spirit makes a Slam attack against that creature if possible, or the spirit moves up to half its Speed toward that creature without provoking Opportunity Attacks.
