When an individual is subjected to prolonged compression, several physiological effects occur that can lead to serious harm or death. The pressure applied to the body restricts blood flow and causes ischemia (reduced blood flow) to the affected areas. As a result, the muscles and tissues become damaged, releasing myoglobin and other cellular contents into the bloodstream. This can lead to acute kidney injury, cardiac problems, and coagulopathy.
As an action, designate a 15-foot radius sphere within your line of sight. The air in this zone instantly pressurizes to lethal levels. All creatures within the area must make a Constitution saving throw. lethal pressure crush
The compression also affects the respiratory system by limiting chest expansion and diaphragmatic movement. This restriction can cause respiratory acidosis, hypoxia, and hypercapnia, which can lead to respiratory failure. Furthermore, the pressure on the body can stimulate the baroreceptors, leading to a reflex vasovagal response, which can cause a sudden drop in blood pressure and cardiac output. When an individual is subjected to prolonged compression,
If you choose to sustain concentration on this ability for a second round, the pressure increases exponentially. Any structure, vehicle, or unattended object in the zone is instantly crushed and reduced to dust. Any creature still inside takes an additional 4d8 damage at the start of their turn as the pressure continues to mount. This can lead to acute kidney injury, cardiac
