shooting in the dark

[calighis]

A cave collapsed on my pc's creating a cloud of dust and littering the floor with loose debris.

I ruled the dust cloud total concealment and the debris rough terrain.

Hill giants threw boulders into the dust cloud.

The cave was walls and ceiling were 10 X 10.

What is the % chance to hit a character and how would I determine who gets hit if the boulders are being launched into the darkness.

What penalties exist for moving over rough terrain like that in the darkness?

50% chance from total concealment naturally.
Hill Giant treated as throwing blinded so -4 penalty to attack roll.
And must guess the spot where you are.

Rough Terrain in Darkness?
Page 163, speed reduction in darkness. 2 for difficultt + 2 for darkness=x4.
So each 5 feet/square is worth 4 sq/20 feet speed.
So to get 30 feet out of there, it would take 120 feet movement; or double moving 3 turns.
