You are sickened for the next ten minutes. You can roll a another Constitution saving throw every minute however to save, but while doing so you're under the poisoned condition.

A poisoned creature has disadvantage on Attack rolls and Ability Checks.

Still I'll allow your previous check to go through unabated. Your survival check reveals that there where many monsters, mostly trogs, who have crossed this body somewhat recently. Scraps against the ground, a stain here and there, all of it fresh too. There aren't any monsters lying in ambush right now but you do know that if you stay too long chances are you'll run into something roaming the ruins. Or rather, it'll run into you.
