How about a massive cold spell for DnD 5e?

Glacier

9th-level conjuration

Casting Time: 1 action
Range: 1 mile
Components: V, S
Duration: concentration, up to 1 minute

You summon forth a glacier of ice from the deepest, darkest heart of  the plane of water.  The Glacier plows through an area 100 feet long by 40 feet wide by 20 feet high.  All creatures in the area the glacier moves through must make a Dexterity saving throw taking 10d6 cold damage and 20d6 bludgeoning damage on a failed save and are frozen in place being restrained and frozen next to the ice, or half as much damage on a successful one and dodging out of the way of the ice.  Creatures struck by the ice are pushed to the front of the glacier.  The ice remains as long as the spell is maintained and any creature that is frozen by the ice or within  10 feet of the ice must make a Constitution saving throw at the end of each of its turns to avoid taking 10d6 cold damage and is restrained as above, or half on a successful save and avoiding being restrained.  Creatures frozen by the ice can take no actions, but if the creature succeeds on its Constitution saving throw, it thaws and may take actions as per normal on its next turn.

One more DnD spell before bed

Casting Time: 1 action
Range: Tough
Components: V, S, M (a steel rod)

You touch a willing creature transferring the power of steel into the creatures body as the rod turns to dust.  The creatures Strength, Dexterity, and Constitution are treated as if they are all 20 for the duration of the spell.  Hit points gained from this spell are real as the creature has been empowered and are gained when the spell is cast, and when the spell ends, extra hit points over the creatures normal total are lost.
