Gas - abunchofhacks/epicinium-documentation GitHub Wiki

Each space can contain up to 2 Gas.

If Gas is present on a space, it lowers the hitpoints of tiles and ground units in that space by 1 (down to 1), making them more vulnerable to damage.

In the Decay phase, Gas deals 3 shots of 1 damage to ground units in an indiscriminate damage step. After this damage is dealt, all spaces with Gas lose 1 Gas. Spaces that had 2 Gas cause surrounding spaces to have gain up to 1 Gas. The Humidity of spaces that still have Gas drops by 1.

Gas can be dropped by Zeppelin units. Gas is also leaked by Zeppelin units, Industry tiles and Airfield tiles when they are destroyed.
