Cool or not cool?
The characters are fighting some Yeti in an icy cave with stalactites and stalagmites and icicles. The Yeti attack is forceful and a character misses while in melee with them.
You as a GM say: “They hit you with a massive backhand punch and you are flung into the air. Take [monster damage]. but man you really won’t like this but you are landing directly in a bunch of spiky ice and rock spikes. Take a d4+3 damage from that”.
Extra damage from environmental stuff that was clearly described to be there? Overkill in such a situation or perfectly fine?
