Also, do you have to stack the spells to get that linear damage .. meaning drop them at the same time?

Or can you drop 1 spell, get 24% damage on the wall, when that spell expires drop a 2nd spell and the damage goes to 48%?

This could be key to the strategy of using this spell -- if you have to drop all 4 at once to get the walls down vs. being able to drop them whenever you want.
