I assume you’re trying to drive a vehicle through the forest. If so, then fire is the best option. Wait for the rain to stop and set several fires. If you want to speed it up, try to make a big fire and let it spread rather than setting small fires. Big flames spread much faster than it takes for small flames to grow. You can then drop flammable items to connect “islands” of trees.
If fire is not an option, your next bet is chopping them down using the construction option. That takes 20 minutes for the tree itself, then 20 minutes for each trunk.
Putting yourself out is currently only possible by diving into deep water. The only other option is waiting it out while healing head and torso with items and bionics.
Fire is incredibly deadly to humans, even power armored ones.
Using fire is safe as long as you never step on anything flammable when a raging fire or medium fire is around. It can spread onto tiles with flammable items, but not onto creatures that don’t stand in it. You can stand next to raging fire while wearing paper armor just fine, as long as there are no flammable items, plants (except grass), wooden furniture or wooden floors on your tile.[/quote]
I was actually trying to clear out a big patch next to my mansion to build a large solar generator car type thing that doesn’t move. Solar panels and storage batteries with recharging stations on it. I used fire, this time i didn’t stand so close to it.
