I am writing a trap that drowns people in soil and sucks them down to a depth of 100'
I am curious on damage this would do. Should it be Con Drain? HP per round? Would this crush them if the soil is loose pack like quicksand?
How would armor impact the crushing?
Since this trap is for levels 1 to 17 I will have to vary the amount of Damage but I feel this is very deadly. Input would be appreciated.
