Lumberjack

Kill 3 people with your axe in one life.


This one is a fairly easy achievement to get normally. When an enemy rushes your position, hide and let them run by. Once you are behind them, leap out and torch them for initial damage. Then run up and axe them in the face. Whether or not you have the axetinguisher doesn't matter, as chances are they will have taken enough damage to fall to your mighty axe. Do this three times (or against a group of three people) and you will get the achievement.

To farm this, have three of your friends play scouts and line up all nice in a row for you. Axe each one in turn, and make sure they don't kill you in the process. If you want, taunt after you kill the last one to work on the Freezer Burn achievement.Really east to farm as long as you don't get killed.

Tip: Can be done with either fire axe or axetinguisher.

Clearcutter

Kill 6 people with your axe in one life.


Much like Lumberjack, you really need to hide in the shadows to get this achievement. Unlike Lumberjack, you should probably hide in the shadows near your own base. This achievement is much easier with the axetinguisher, so getting it before you do the achievement will simplify your efforts greatly. Just toast and chop away, making sure to stay alive. You may want to tackle individual enemies instead of large groups to keep yourself alive.

To farm this, do much like you did for the lumberjack achievement, except do it twice! There's nothing special to it. Just swing, hit, collect your kill, and move on.

Tip: Like Lumberjack, can be done with both axe and axetinguisher.

Firewatch

Ignite 10 snipers while they are zoomed in.


This one can be hard or easy, depending on the strength of the opposing team's defense. The best map to do this on is 2fort. Rush through the base and to the battlements. Flame any snipers up there and then drop down below. Rinse and repeat until you've set 10 on fire. You don't have to kill the snipers, but doing so will help your team and further the Firefighter or Pyromancer achievement. Also remember that it doesn't have to be done in a single life, so you can afford to die.

To farm this, get a sniper and a medic combo near you. Have the sniper zoom in to somewhere in the distance, and set him on fire. Have the medic remove the flames, and repeat. Doing it ten times will snag you this wondrous achievement. Alternatively, get a team of snipers to zoom in and sweep them with the flamethrower.

Tip: You can tell if a sniper is zoomed in if their face is pressed against the stock of the gun, looking through the sights. Don't bother setting snipers on fire that aren't aiming if you are going for this achievement.

Burn Ward

Ignite 3 medics that are ready to deploy an Übercharge.


This one, much like most of the ignite achievements, doesn't have to be done in a single life. To do this one normally, just go medic hunting. You are most likely to find medics with übercharge near heavies, soldiers, and demomen, because those classes seem to be the ones that soak up the damage. Make sure you catch them by surprise, so they don't activate their übercharge before you can arrive, ruining your plan.

To farm this, it's best to get three friends that are working on medic achievements. When they get übercharge all filled up, set them on fire. Requires very little effort on your part, thankfully. If you get four medics, one can even work on Autoclave (by übering you while you torch the medics). You don't have to kill the medics.

Tip: You can tell if any medic, friendly or not, has an übercharge by looking at the medigun. If lightning and sparks are flashing around the barrel, they have übercharge and should be a target.

Makin' Bacon

Kill 50 Heavies with your flamethrower.


This is a great achievement to work on in tandem with Firefighter as well as Burn Ward. Basically, hunt down medic and heavy combos and burn them alive. Be extremely aggressive, otherwise the heavy will make short work of you with his minigun. Also, make sure to take out the medic first. Once you toast 50 of the big guys, you'll get this achievement. If you go for heavy and medic combos, you'll also easily snag the Next of Kindling achievement.

To farm this, get a couple of friends willing to be toasted by your pyromaniac self. Have them play heavies and mow them down. You don't have to do it in a single life, but it's easier to farm if you don't die at all in the process. You have to kill the heavies as well, not just ignite them. If a medic is on the opposing team, have him heal the heavy as well and torch the both. You'll next the Next of Kindling achievement for your efforts.

Tip: The backburner, if you have it, is a great way to work on this achievement thanks to the critical bonuses

Plan B

Kill 10 enemies while you're both underwater.


This one is a lot easier than it seems. Since you don't really have to worry about range, just switch to a shotgun when you go underwater and blast away. You can also lurk under the water and surprise enemies with a firm axe chop to the neck if you so wish. Just don't try and use your flamethrower, for obvious reasons, unless you like to die. The best place to lurk underwater is the center pool in 2fort.

To farm this achievement, have opposing scouts jump into the center pool of 2fort as soon as they spawn. Then proceed to blast them away with your shotgun. After ten fall and limply float on the water surface, you will unlock the achievement. Scouts are the best for this because of their low amount of health, but any class will do. It's also good to farm the Clearcutter achievement while you are doing this, as axes work underwater just fine.

Tip: Underwater is counted as anywhere that has the player floating. Therefore, the sewers sections leading away from the center pool in 2fort can't be used to work on this achievement.
