i would like to see a new pressure blocking material other than titanium but with a weakness like neutrons go through it
TTAN already has 3 weaknesses; it can only block pressure if a line of it is at least 3 pixels thick (setting the tmp to 1 doesn't work), it lets pressure pass when sparked, and it's more susceptible to ACID and CAUS than any other element.
pipe + ttan tmp 1
