attacks and other effects outside the remorhaz, and it 
takes 10 (3d6) Acid damage plus 10 (3d6) Fire damage 
at the start of each of the remorhaz’s turns. 
 If the remorhaz takes 30 damage or more on a single 
turn from a creature inside it, the remorhaz must suc-
ceed on a DC 15 Constitution saving throw at the end 
of that turn or regurgitate all swallowed creatures, each 
of which falls in a space within 5 feet of the remorhaz 
and has the Prone condition. If the remorhaz dies, any 
swallowed creature no longer has the Restrained condi-
tion and can escape from the corpse by using 15 feet of 
movement, exiting Prone.
