Cleave

Effect

Each Creature in a 15-foot cone must make a Dexterity saving throw.

• On a failure: 3d10 force damage
• On a success: half as much damage 

Adaptive severing

For this spells damage

• Damage resistance is ignored
• Damage immunity is treated as resistance

This does not apply to effects that completely negate damage (such as invulnerability)

Follow Through Cut

Creatures that fail the saving throw have their speed reduced by 10 feet until the start of your next turn as their bodies struggle to hold together.

Severing Logic

• Nonmagical objects and structures in the area take maximum damage
• thin barriers (wood, stone, bone) show clean seams where the cut passed

 if this spell reduces a creature to 0 hit points, the wound is impossibly clean -no burn, no tear, just sudden division

At Higher levels

When you cast this spell using a spell slot of 3rd level or higher, increase the damage by 1d10 for each slot level above 2nd
