Eschar Trap

You create a trap which can be manipulated within a 60 foot range. Once a large or smaller creature steps into the trap you manipulate the 'healing or oxidization' process of the blood to cause it to coagulate and become solid. Once solid, you can no longer manipulate it as you would normal free standing blood. The creature can make a dexterity check to avoid being trapped and on a fail can make a strength check to escape the trap. Trap does not stop the creature from making attacks from their position, it only acts as a grapple.
