This cube is about an inch across. Each face has a distinct marking on it that can be pressed. The cube starts with 36 charges, and it regains 1d20 expended charges daily at dawn.
You can use an action to press one of the cube's faces, expending a number of charges based on the chosen face, as shown in the Cube of Force Faces table. Each face has a different effect. If the cube has insufficient charges remaining, nothing happens. Otherwise, a barrier of invisible force springs into existence, forming a cube 15 feet on a side. The barrier is centered on you, moves with you, and lasts for 1 minute, until you use an action to press the cube's sixth face, or the cube runs out of charges. You can change the barrier's effect by pressing a different face of the cube and expending the requisite number of charges, resetting the duration.
If your movement causes the barrier to come into contact with a solid object that can't pass through the cube, you can't move any closer to that object as long as the barrier remains.
Face | Charges | Effect |
---|---|---|
1 | 1 | Gases, wind, and fog can't pass through the barrier. |
2 | 2 | Nonliving matter can't pass through the barrier. Walls, floors, and ceilings can pass through at your discretion. |
3 | 3 | Living matter can't pass through the barrier. |
4 | 4 | Spell effects can't pass through the barrier. |
5 | 5 | Nothing can pass through the barrier. Walls, floors, and ceilings can pass through at your discretion. |
6 | 0 | The barrier deactivates. |
The cube loses charges when the barrier is targeted by certain spells or comes into contact with certain spell or magic item effects, as shown in the table below.
Spell or item | Charges Lost |
---|---|
Disintegrate | 1d12 |
Horn of blasting | 1d10 |
Passwall | 1d6 |
Prismatic spray | 1d20 |
Wall of fire | 1d4 |
Notes: Control, Warding
yes, but note, for side 5, you also take falling damage and for side 4 as well, you would still either hit the side of the cube or pass through the cube and hit the wall
no, the cube of force does not prevent damage from falling.
if you fall and activate the cube, the cube reaches the ground 5feet before you do assuming your medium, either if you allow the cube to go down into the earth allowing you to land on the ground or the cube floats on the surface and you fall into the cubes floor still taking the fall damage. you are not suddenly suspended or floating in the ari, you land and take damage.
depends on the side used. each side only applies 1 effect, excluding side 5 which applies all the prior effect and technically whatever the DM decides.
my questions are.
assuming side 5 is pressed blocking everything. including "spell effects"
1.Misty step: an opponent can not misty step into the cube. since the cube blocks spell effects from entering, the effect of the misty step spell is teleportation, therefore the effect is prevented from entering. it is not a valid location, however, the PC inside the cube may cast misty step on it's self and teleport as the spell effect is not passing through it is moving the cube with the caster.
2. when a caster is inside the cube of force, spell effects that originate outside the barrier can still be cast targeting outside the barrier, so long as no portion of the effect must originate from the caster and travel to the target. this means you can activate the cube and still cast a summoning spell that allows you to choose where the creatures appear. IE summon elemental, conjure woodland, etc.. others like summon familiar would place the summoned creature inside of the cube but would still function. this would also mean compulsion effects and enchantments etc. may be valid depending on the wording of the spell.
3. what if on the floor your walking on has a pebble on it? are you prevented form moving, does it count as floor, if the pebble can pass through then dropped items can, if the pebble blocks movement are you capable of jumping over/around it? does the pebble get pushed with the cube???
If your movement causes the barrier to come into contact with a solid object that can't pass through the cube, you can't move any closer to that object as long as the barrier remains.
i mention this because a lot of DM's like to Nerf this item making it useless, or there is quite a bit of confusion regarding how theses interact and Crawford and them really have not spelled it out. they speak about wall of force, but that's not the topic. FORCE CUBE alone.
replace pebble with caltrops alone a 15 foot corridor for 100 feet.
RAW the barrier is 5 feet below your feet and 5 feet above your head at all times, so you could theoretically jump on top of the caltrops and then be the cubes floor would be over the trap while you walked on top of the barrier caltrops... although weirdly your walking on the cubes surface inside so you might be a spinning cube to actually get forward momentum.....
Says it magically appears 15' sides and is centered on you. So, no.
This item is bonkers OP for a rare item...
As a DM I would say that caltrops and pebbles would simply be pushed away given that they are loose objects and a light enough to forgo a str check.
On another note, I wonder if a spell caster could use the cube and cast the fly spell to carry allies on the top face.
