[RPG] What space does the spell Cloud of Daggers fill


I am trying to workout what template cloud of daggers (PHB, p. 222) would be on a grid. The spell states:

You fill the air with spinning daggers in a cube 5 feet on each side, centered on a point you choose within range.

So does that mean it would look like this:

cloud type 1

Or like this:

cloud type 2

From what I've read online, there seems to be some suggestion that it is a single square (tile) though this does stack with the spell description of "a cube 5 feet on each side".

Clearing this up for my group would be great, and I am sure our DM will be pleased as his monster were nicely diced by this spell. Thanks.

Cloud of daggers fills one 5-foot square.

Neither of the options that you show are correct. The spell description states that it takes up:

a cube 5 feet on each side

Since one square is five feet by five feet, you can fill one square with the cloud. If you target the center of a grid cell, then the spell fills that entire grid cell.

Note that the spell does not have a 5 foot radius. "5-foot radius" and "a cube 5 feet on each side" are very different measurements. A spell with a 5 foot radius fills a circle 10 feet wide. A spell that fills a cube 5 feet on a side fills a square, and that square is only 5 feet wide.
