It’s probably easy to implement.
If someone were to write a good, well thought of algorithm of how it should work, I could write up a PR and see what devs think of the idea.
By “algorithm” I mean things like time taken per stomp, chance of item damage (involving item’s fire resistance - no way nomex boots will ever get damaged by fire), chance of player damage (using relevant clothing’s environmental resistance), chance of fire dying/dropping to small fire (possibly with penalty for bad stats/survival skill), possibly also using items other than just boots (we could then have a nomex blanket to “smash” non-small fires).
By “well thought” I mean spending at least 5 minutes thinking up different scenarios like “unskilled clumsy survivor in firefighter gear trying to stomp out regular fire” or “naked masochist survivalist stomping hot coals” and thinking about what would algorithm do with those stats, what would be the chance of success and how bad would be the damage.
