You create five 1-foot cubes of magical force known as dara blocks. Each dara block appears in a different unoccupied space of your choice within range and becomes magically fixed in place. The blocks are invisible to all creatures except you and any creature you designate when you cast the spell. A creature that can see the dara blocks (including one benefiting from See Invisibility or truesight) sees a luminous cube made of a transparent, dark green light.   A block fixed in the air can hold up to 5,000 pounds of weight. More weight causes the block to fall. A creature can use an action to make a Strength check against your spell save DC, moving the fixed block up to 10 feet on a success.
