Cajole the land

You cause earth, trees or live water to take on
the shape you desire (effect size: 15 ft cube).
This alteration is as stable as the shape permits.
Minimum, until the end of your next turn.
Should a creature suffer adverse effects from this
power (damage or status: restrained, blinded,...),
it gets a ST (your spell save DC) to escape.
The pirates say Shapers command the jungle.
Shapers say, the land simply knows them.
