Description

Squirming, ebony tentacles fill a 20-foot square on ground that you can see within range. For the duration, these tentacles turn the ground in that area into Difficult Terrain. Each creature in that area makes a Strength saving throw. On a failed save, it takes 3d6 Bludgeoning damage, and it has the Restrained condition until the spell ends. A creature also makes that save if it enters the area or ends it turn there. A creature makes that save only once per turn. A Restrained creature can take an action to make a Strength (Athletics) check against your spell save DC, ending the condition on itself on a success.

School Fit

Conjuration spells are creation magic in the loose sense — not creation from nothing, but creation from elsewhere. They borrow a creature from the planes or a body of water from a far lake. Black Tentacles sits among the Conjurations on the strength of the spell places matter or creatures into the world that were not there before the cast. Mid-tier casters can usually cast Black Tentacles once or twice per long rest.

Class Fit

  • Wizard: At tier 1 Wizards have small prepared lists. Black Tentacles earns its place by either being always-relevant (Shield, Mage Armor) or by being the right answer to a known problem. Black Tentacles's concentration requirement makes it vulnerable to a single failed save when the caster takes damage.
