Building Blocks of Pharius

Magical semi-translucent building blocks appear on unoccupied spaces originating from a point that you can see withing range. This construct can be destroyed by dispelling it with dispel magic or by a disintegrate spell. These blocks can be physically interacted with, but are not affected by gravity. Any creature attempting to move through the blocks must succeed a Strength saving throw or have their speed reduced to 0 after exiting the construction, after which the construction reforms. If a creature ends their turn inside the construction, they are pushed to the closest unoccupied space.

You create one of the following constructions:

Regular strength: Constructions may take up to 6 5-foot cubes in any formation as long as they make a single structure. These blocks provide 1/2 cover to creatures fully covered by them. These blocks can support the weight of one medium-sized creature for each cube.

Re-enforced strength: Constructions may take up to 3 5-foot cubes in any formation as long as they make a single structure. These blocks provide 3/4 cover to creatures fully covered by them and can support the weight of one large-sized creature for each cube.

Concentrated strength: Constructions may take up to 1 5-foot cube in any formation. This construction provides full physical cover against attacks (but not against spells that rely on sight) and can support up to 8,000 pounds of weight and can withstand almost any impact.
