Entangle

Vines or roots rapidly grow or move to try to ensnare the target.

This spell does not affect incorporeal targets.
The target must be within 30 ft. of the ground, wood, or another source of plant matter for this spell to reach them. (Bringing a wooden staff might be wise).

The target takes earth damage.
The target gets a health (reflex) save.

Fail:
The target is restrained.

Restrained:
You are immobilized.
You have disadvantage on rolls to hit.
You are off guard (rolls to hit you have advantage).

The target may spend their move or action to try a DC 10 test of Strength or Roguery to free themselves.

An adjacent ally may spend their action to try their own DC 10 test of Strength or Roguery to free the target.

The target may also be freed by inflicting 50 total damage to the roots or vines entangling them. The roots or vines have 10 AC and are weak to slashing and fire damage.

Pass:
The target’s Speed is halved until the end of its turn.

Alternatively, you may use Entangle to rapidly grow, bend, or manipulate roots, vines, wood, or other vegetation, to an extent limited by this spell’s range.
For example, you can cast Entangle on an entangled creature to free them,
or to try a contest of Spellcraft against a target’s Strength to grab them with vegetation and pull them a distance based on their size if you win (Medium: up to 15 ft., Larger: -5 ft. per size, Smaller: +5 ft. per size.),
or to root yourself to the ground, immobilizing yourself and allowing you to contest any attempt to move you an additional time with a test of Spellcraft,
or if you begin falling near a vine, you may make it grow towards your hand to catch yourself,
or you can create or open a wall made of a twisted gnarl of roots up to 5 ft. wide, long, and tall.
