Dara Blocks

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.
At Higher Levels. When you cast this spell using a spell
slot of 4th level or higher, you can create two additional
dara blocks for each slot level above 3rd.
